64 Quotes on Persistence to Help Your Journey With Parkinson’s Disease

“Kites rise highest against the wind – not with it!” Winston Churchill

“Energy and persistence conquer all things.” Benjamin Franklin

Introduction: On January 1, LinkedIn announced that I had a work anniversary of 32 years at The University North Carolina at Chapel Hill ( if you include my postdoc at UNC-CH, this is a grand total of 36 years). My dear friend Lisa Cox (she is a graduate of The University North Carolina at Chapel Hill) wrote to congratulate me and said the following: “Grateful for your commitment to the University and to your students. Your steadfast determination is to be commended.”  Her use of the words ‘steadfast determination’  got me thinking about the word persistent  (steadfast is a synonym for persistent) and this thinking led to the current blog post.

Persistence in the backdrop of staying hopeful:  I truly admire and enjoy reading works by Dr. Brené Brown. Her insight, research/writing and her thoughtful commentary on many different topics are truly remarkable.  She has studied hope when you have Parkinson’s hope is a very important word to embrace.  One of her stories on hope, mixed with persistence, deals with the work of C. R. Snyder, at the University of Kansas, Lawrence.  Embracing and expanding upon this work, “hope is a thought process; hope happens when (1) We have the ability to set realistic goals (I know where I want to go); (2) We are able to figure out how to achieve those goals, including the ability to stay flexible and develop alternative routes (I know how to get there, I’m persistent, and I can tolerate disappointment and try again); and (3) We believe in ourselves (I can do this!).” To read in-depth this presentation entitled “Learning to Hope–Brené Brown”, click here. And again the word ‘persistent’ stood out while reading this document.

Persistence and Parkinson’s: Persistence (per·sist·ence /pərˈsistəns/ noun) is defined as (1) firm or obstinate continuance in a course of action in spite of difficulty or opposition, and (2) the continued or prolonged existence of something.  If you’re going to thrive in the presence of Parkinson’s, you will definitely need persistence because you will be locked in a lifelong battle to resist its presence every minute of every day.  Besides being hopeful and positive, having persistence will help enable your daily journey with Parkinson’s.  In other words, persistence is not giving up without trying,  searching out and exploring new pathways for your life, and it certainly demands steadfast determination.

Motivation using quotes on persistence and pictures/diagrams/ideas related to Parkinson’s:  I am a very visual person and I also need motivation as the new year begins with winter cold in North Carolina  (yes, we got some snow/freezing rain/ice, and yes Chapel Hill was mostly brought to a standstill; so we move on and hope for an early spring).  Therefore, to help me stay motivated to exercise every day,  and to remind me of all the benefits that exercise provides me against Parkinson’s progression I made the following images.

 

 Also displayed below are 12 additional quotes mounted on some colorful artful backgrounds.   Hopefully, this will provide you a template to make your own favorite motivational group of persistence quotes.

Please stay focused on taking the best care of you by working well with your family and support team, be honest with your movement disorder Neurologist, get plenty of exercise and try to sleep well.  You hold the key to unlock the plan to manage your Parkinson’s.

“Strength is found in each of us.  For those of us with Parkinson’s, we use our personal strengths of character to bolster our hope, courage, mindfulness/contentment/gratitude, determination, and the will to survive. Stay strong. Stay hopeful. Stay educated. Stay determined. Stay persistent. Stay courageous. Stay positive. Stay wholehearted. Stay mindful. Stay happy. Stay you.”  Frank C. Church

7 Tips and Healthy Habits for Working with Parkinson’s

“Nothing will work unless you do.” Maya Angelou

“The best preparation for good work tomorrow is to do good work today.” Elbert Hubbard

Précis: Over the past eight weeks, some loyal readers and several friends have asked me: “Is everything  okay?”; “Has my health taken a downturn?”; “Have you stopped writing your blog?”; “I have been worried about you because it has been well over six weeks since your last blog post.”  I responded to each that I was well and doing fine, my health has been steady. However, the fall semester (early August-early December) for me is over-flowing with my job/work (teaching, administrative and still trying to maintain some research) and other commitments (service) [let alone trying to find time to exercise and other personal time], which leads to very little spare time to even think about composing a blog post. I apologized to everyone who contacted me; and I do stand in awe of all of the bloggers I follow who are able to both write and work full-time at the same time.  Thus, the topic for the current post is about having a career/full-time job in the presence of Parkinson’s disease.

“The world is full of willing people; some willing to work, the rest willing to let them.” Robert Frost

There is an old saying that ‘there are people who work to live’ and that ‘there are people who live to work’: One of these phrases likely describes your attitude (or opinion) about your job/career.  One phrase is not more correct than the other phrase. Likely, one phrase will matter in which career path you follow and it will contribute to your overall satisfaction in work-matters.  Thus, an honest assessment will help you identify which of these beliefs you most are aligned with as your life and career unfolds.  Your happiness matters.

I have been in an academic medicine setting for the past 35 years and I am more closely linked with the phrase ‘live to work’.  I have never regretted this career choice.  It has taken me a long time to understand the how and the why of my academic career successes and advances mixed with the typical setbacks/compromises.  A dear friend recently told me she could not imagine me doing anything else career-wise, it’s a perfect match. Currently, I am still able to work 6 days/week with the following goals: educating future healthcare providers, serving on several committees, and planning that next experiment to get one more research proposal submitted/funded.  Then Parkinson’s happened.

“The only place success comes before work is in the dictionary.” Vince Lombardi

The equilibrium between life and career: The “life-work equation” is now of primary importance to me.  My version can be summarized as given below (likely, you’d have different/additional variables in your own ‘personal’ life-work equation):

Health (exercise and living with Parkinson’s) + Living (importance of loved ones, family, friends, colleagues) + Career (teaching and research) = Life.

The spectrum of balancing life-work ranges from happy/positive/fulfilling to unhappy/unfulfilling/find something else to do/not enough time to manage my Parkinson’s.  Ultimately, at 64 years of age, and with Parkinson’s, I need to consider adding another possibility (or dimension) to my life-career equation, namely retirement.  Well, at least, the thought has been planted.

“The only way to do great work is to love what you do. If you haven’t found it yet, keep looking. Don’t settle.”  Steve Jobs

7 tips and healthy habits for working with Parkinson’s: Clearly, understanding and balancing your career is an important aspect to your life (something that has not always been obvious to me).  Taking care of your health and career, especially in the presence of Parkinson’s is of paramount importance and will contribute to your wellness and happiness.  These are straightforward suggestions for you to consider while working with Parkinson’s; hopefully, this list will serve as a reminder about their importance. Also shown below are several photos of me at work and at play. Here is a 1-page summary of the “7 Tips and Healthy Habits for Working with Parkinson’s” (Click here to download file).

17.12.26b_7 Habits For Working with PD

[1] Executive Function. Executive function describes the group of mental skills that help you get things done. The frontal lobe of the brain controls your ability to execute these skills.  There are three key features to executive function: (1) working memory allows you to keep information in your mind and use it appropriately; (2) cognitive flexibility is being able to think about something in more than one way; and (3) inhibitory control  is being able to ignore something and resist temptation. Executive function allows you to manage time, pay attention, plan and organize, remember details and the ability to multitask.  Many with PD show a slow erosion of executive function. You need to recognize this aspect of your mind is partly responsible for your ability to work well (or not); therefore, keep going as best you can. 

executivefunctioncoaching3“The essence of strategy is choosing what not to do.“ Michael Porter

[2] Be willing to discuss your disease.  You have made the decision to inform others about your Parkinson’s and tell your friends and colleagues. Good for you!  In my case, I spent almost a year trying to avoid telling people about my Parkinson’s. Instead I just informed people who worked with me, my family and close friends. In hindsight, living openly with Parkinson’s is so much easier because everyone has been very supportive, receptive and very caring. To most people, Parkinson’s is a mystery. And it gets more difficult, not easier, when your colleagues (family and friends) acknowledge that they know about Michael J. Fox, Robin Williams and Mohammad Ali.  Educating your colleagues about you, your issues, your disease gives you so much credibility and bolsters respect among your peers.

This above all; to thine own self be true.” William Shakespeare

[3] Stay positive and go forward. At times, you live negatively and go backwards. Focus on staying positive and practice moving forward; your co-workers will appreciate the effort. A constant theme of this blog has been to try to remain positive and to live in a forward manner and not look backwards. We can reflect on today and you can plan for tomorrow all you can do is relive yesterday. It’s much better to stay positive and go forward.

Always turn a negative situation into a positive situation.” Michael Jordan

[4] Exercise, sleep and eat well. In the absence of regular exercise, adequate sleep and a healthy diet you’ll be unable to work effectively.  Just do all three each day; everyone around you at work will care for you even more, why?  Because you are now positively fueling your entire body-mind. Go here for a few additional blog posts on these topics: exercise (9 Things to Know About Exercise-induced Neuroplasticity in Human Parkinson’s; Golf And Parkinson’s: A Game For Life; Meditation, Yoga, and Exercise in Parkinson’s); sleep (Sleep Disturbances in Parkinson’s and the Eagles Best Song Lyrics; Sleep, Relaxation, And Traveling; 7 Healthy Habits For Your Brain); and nutrition (Diet and Dementia (Cognitive Decline) in the Aging; B Vitamins (Folate, B6, B12) Reduce Homocysteine Levels Produced by Carbidopa/Levodopa Therapy).

A lifestyle is what you pay for; a life is what pays you.” Thomas Leonard

[5] Stress reduction and mindfulness. Cortisol is produced as a by-product from stress.  Mindfulness reduces stress to reduce cortisol levels, a winning scenario for you at work and your brain will be healthier.  Take time during the work-day to practice mindfulness; even 5’ daily improves your body-heart-mind-soul axis.

Men for the sake of getting a living forget to live.” Margaret Fuller

[6] Gadgets can make a big difference.  Technology today is simply amazing; take advantage of it to keep going in your job. For example, if you type a lot on a keyboard/computer, use dictation with Dragon®. If your posture is poor from sitting all day at a desk, get the BackJoy® and help better support your back.   I  definitely have  a tendency to sit too long when I’m focusing on work and writing; one way I deal with it is to have Alexa (my Amazon Echo Dot®) set a timer for every 20 minutes to get me up and stretching.  I also have my Fitbit Charge 2® exercise watch set in silent alarm mode to vibrate every five and six hours, respectively, to remind me to take my medication. Just a few examples of many.

Technology feeds on itself. Technology makes more technology possible.” Alvin Toffle

[7] Have a career plan with accommodations. Let’s  be realistic and accept the notion that our PD symptoms may eventually interfere with our work.  Be self-aware of these small physical/mental changes; be prepared (proactive) and have a Plan B or a Plan C ready to implement. Consider that stopping work and being diagnosed with Parkinson’s are both typically at 60 something years of age, which makes the intersection of job and PD diagnosis/progression a very important “X marks the spot”.

I never think of the future – it comes soon enough.” Albert Einstein

Working while with Parkinson’s:  I have had Parkinson’s for the past ~6 years, and I am still working full-time.  No doubt Parkinson’s affects each person differently; it allows some to continue to work and others must stop.   For the past two years, I’ve been contemplating a couple of different plans once I stop working full-time. They consist of phasing-out retirement, exercise, PD outreach, teaching, and a few other ‘opportunities’ that I’m not yet ready to describe because they are still being developed. My future will likely be as busy as I am now but not necessarily all at the same place or at the same time.  When the full-time clock stops ticking it will be because either “it’s time, I’ve done enough” or my health has interfered with my schedule. My plan is still a couple of years away from being implemented. Like everyone with Parkinson’s, I’m acutely cognizant of my disorder. In the meantime, I have much left to accomplish with my education-science-service-outreach.

“Thunder is good, thunder is impressive; but it is lightning that does the work.” Mark Twain

“Beingness, doingness and havingness are like a triangle where each side supports the others. They are not in conflict with each other. They all exist simultaneously. Often people attempt to live their lives backwards: They try to have more things, or more money, in order to do more of what they want, so that they will be happier. The way it actually works is the reverse. You must first be who you really are, then do what you need to do, in order to have what you want.” Shakti Gawain

Effect of Forgiveness on Health

“When you forgive, you in no way change the past – but you sure do change the future.”  Bernard Meltzer

“The first step in forgiveness is the willingness to forgive.” Marianne Williamson

Précis: Recently had a friend go through a difficult break-up from a marriage. The notion of getting past the failed relationship, achieving forgiveness, and moving on without causing illness was of paramount importance. The implications of forgiveness/unforgiveness as it relates to health-illness crossed my mind. It started with assembling the quotes in this post. Next, I did a Google Scholar search for “forgiveness and health” and discovered a whole new area of psychology-science-medicine (well, it was new to me). Most of us would agree that forgiving yourself promotes wellness; whereas remaining unforgiven could disrupt your mental and possibly even your physical health.  This post reviews forgiveness and its positive impact on our health.

“Forgiveness is really a gift to yourself – have the compassion to forgive others, and the courage to forgive yourself.” Mary Anne Radmach

Forgiveness and Health: The Oxford dictionary defines ‘forgive’ as to stop feeling angry and resentful towards (someone) for an offense, flaw, or mistake.  Positive psychology is the scientific study of the strengths that enable individuals and communities to thrive. Forgiveness is a big part of positive psychology regarding both physical and mental well-being.   Over the past 15 years, researchers have focused on 2 primary hypotheses: (1) forgiveness has important connections to physical health; and (2) this relationship is guided by an association between lack of forgiveness and anger.  Evidently, there is consensus in the field that these two primary processes form the basis of forgiveness: (i) letting go of one’s right to resentment and negative judgment; and (ii) fostering undeserved compassion and generosity toward the perpetrator.  The first process implies a person would reduce their negative emotions (i.e., anger and revenge); while  the second process involves increasing positive feelings and might even include reconciliation. Collectively, there is growing scientific evidence that links the positivity of forgiveness and health.

“He who is devoid of the power to forgive is devoid of the power to love.” Martin Luther King, Jr.

“The more you know yourself, the more you forgive yourself.” Confucius

Forgiveness vs. Unforgiveness: It is probably apparent (to you) that forgiveness is generally associated with improved mental and physical health, as opposed to someone unable/unwilling to forgive.  Modeling the relationship between forgiveness and health, based on the hypothesis that forgiveness reduces hostility (and this would be considered healthier), 6 paths linking forgiveness and health have been described: (i) decrease in chronic blaming and anger; (ii) reduction in chronic hyper-arousal [“a state of increased psychological and physiological tension marked by such effects as reduced pain tolerance, anxiety, exaggeration of startle responses, insomnia, fatigue and accentuation of personality traits.”]; (iii) optimistic thinking; (iv) self-efficacy to take health-related actions; (v) social support; and (vi) transcendent consciousness (“state achieved through the practice of transcendental meditation in which the individual’s mind transcends all mental activity to experience the simplest form of awareness“).

What does this mean? The majority of studies on forgiveness indicate a reciprocal relationship to hostility, anger, anxiety and depression.  Forgiveness may directly alter sympathetic reactivity, which is often referred to as the “fight-or-flight” response. These responses include increases in heart rate, blood pressure, cardiac contractility, and cortisol.  This implies that unforgiveness could promote an acute, stress-induced reactivity that could be associated with general health problems.  However, it is much more complicated than this simplistic flow of events: anger is a component of unforgiveness; anger is a health risk; therefore, unforgiveness is a health risk.  This is really interesting reading but way beyond my training as a protein biochemist (If interested, look over the references listed below)

Forgiveness and Mental Health: Let’s take a different angle by looking at mental health. We begin with unforgiveness as being associated with stress from an ‘interpersonal’ offense and stress is associated with diminished mental health. Furthermore, unforgiveness due to an ‘intrapersonal’ wrongdoing may lead to shame, regret and guilt, which could also negatively affect mental health. The positive impact of forgiveness may help correct the downturn in mental health that resulted from either interpersonal or intrapersonal stress.  In many instances, mental health is linked to physical health. This suggests that practicing forgiveness would positively influence mental health and could therein bolster physical health.

To summarize the ability of forgiveness to bolster mental health, I have re-drawn the figure from Toussaint and Webb  (2005) as a 4-piece puzzle. It begins with the ‘direct effect’ of forgiveness as told through unforgiveness with emotions of resentment, bitterness, hatred, residual hostility, and fear. The negative emotions of unforgiveness could contribute significantly to mental health problems.  By contrast, the emotion of forgiveness is positive and strong and love-based that could improve mental health. The ‘indirect effect’ of forgiveness through social support, interpersonal behavior and health behavior are all positively-linked to good mental health. The ‘developmental stage’ describes the recognition of the problem, need for an alternative solution, and ultimately the effect of forgiveness augments mental health.  The final piece to the puzzle is the ‘attributional process’, which suggests that being able to forgive bolsters personal control of one’s life, which is perceived to be positive.  By contrast, unforgiveness blocks this life-controlling process by consumptive negative emotions made worse in the individual through rumination.  Due to my own internal word limit and time-period to read/understand the topic, I have not included the religious or spiritual basis of the forgiveness of God, feeling God’s forgiveness, and seeking God’s forgiveness in the narrative of this post.  For many people, these would be integral components to the discussion here on forgiveness and its overall impact on both mental and physical health.

Forgiveness.2

“I don’t know if I continue, even today, always liking myself. But what I learned to do many years ago was to forgive myself. It is very important for every human being to forgive herself or himself because if you live, you will make mistakes- it is inevitable. But once you do and you see the mistake, then you forgive yourself and say, ‘Well, if I’d known better I’d have done better,’ that’s all.” Maya Angelou

9 Steps to Forgiveness (Fred Luskin, LearningToForgive.com): Dr. Luskin is a noted-researcher in the field of forgiveness. His belief is that by practicing forgiveness, your anger, hurt, depression and stress will all be reduced and it will increase feelings of hope, compassion and self confidence. Furthermore, he believes that practicing forgiveness contributes to healthy relationships and to improved physical health; here are the 9 steps to forgiveness:

  1. Know exactly how you feel about what happened and be able to articulate what about the situation is not OK. Then, tell a trusted couple of people about your experience.
  2. Make a commitment to yourself to do what you have to do to feel better. Forgiveness is for you and not for anyone else.
  3. Forgiveness does not necessarily mean reconciliation with the person that hurt you, or condoning of their action. What you are after is to find peace. Forgiveness can be defined as the “peace and understanding that come from blaming that which has hurt you less, taking the life experience less personally, and changing your grievance story.”
  4. Get the right perspective on what is happening. Recognize that your primary distress is coming from the hurt feelings, thoughts and physical upset you are suffering now, not what offended you or hurt you two minutes – or ten years – ago. Forgiveness helps to heal those hurt feelings.
  5. At the moment you feel upset practice a simple stress management technique to soothe your body’s flight or fight response.
  6. Give up expecting things from other people, or your life, that they do not choose to give you. Recognize the “unenforceable rules” you have for your health or how you or other people must behave. Remind yourself that you can hope for health, love, peace and prosperity and work hard to get them.
  7. Put your energy into looking for another way to get your positive goals met than through the experience that has hurt you. Instead of mentally replaying your hurt seek out new ways to get what you want.
  8. Remember that a life well lived is your best revenge. Instead of focusing on your wounded feelings, and thereby giving the person who caused you pain power over you, learn to look for the love, beauty and kindness around you. Forgiveness is about personal power.
  9. Amend your grievance story to remind you of the heroic choice to forgive.

“Forgiving does not erase the bitter past. A healed memory is not a deleted memory. Instead, forgiving what we cannot forget creates a new way to remember. We change the memory of our past into a hope for our future.” Lewis B. Smedes

Forgiveness in the Presence of Parkinson’s:  Receiving a diagnosis of Parkinson’s, a lifelong chronic progressive neurodegenerative disorder is a real shock.  The diagnosis comes with a variety of emotions. After a while, acceptance takes over; no, not your identify, just ok, I’ve got Parkinson’s, live through it, make the most of this experience. Eventually I had to put forgiveness into part of this living-life-equation. There were two self-involved events where I might have contributed to the development of my own disease.  The first was as a young boy in the summertime riding my bicycle behind the DDT trucks spraying for mosquitoes on our Air Force bases [Dichlorodiphenyltrichloroethane (DDT) is a colorless, tasteless, and almost odorless crystalline organochlorine known for its insecticidal properties]. DDT is one of the known chemical inducers of Parkinson’s. Second, in graduate school before OSHA took over regulating lab safety, I routinely used many different noxious compounds for the benefit of science and for the completion of my PhD. Both events caused me to pause and ponder; however, I decided to forgive myself. I truly believe had I remained unforgiving, I would have paved a path of ill health.

This whole process of dealing with the emotion from diagnosis to acceptance (and forgiveness) of Parkinson’s reminds me of the opening verse of “We Are The Champions” by Queen: “I paid my dues/ time after time./ I’ve done my sentence/ but committed no crime./ And bad mistakes-/ I’ve made a few./ I’ve had my share of sand kicked in my face/ but I’ve come through./  (And I need to go on and on, and on, and on)

The vast majority of people with Parkinson’s are 60-years of age or older (although there is a group of early-age-onset). Interestingly, in a recent study with an elderly population, forgiveness showed positive and significant association with mental and physical health.

“You cannot travel back in time to fix your mistakes, but you can learn from them and forgive yourself for not knowing better.” Leon Brown

“Accept the past as past, without denying it or discarding it.” Mitch Albom

Forgive Ourselves: Dr. Elaine in her post “The-healing-power-of-forgiveness” nicely summarized self-forgiveness: “We tend to believe that forgiveness supports the transgression that has been committed against us. But forgiveness is not an endorsement of wrongdoing; rather, it’s an act of releasing the pain and hurt it caused through love, the root of forgiveness—and it is not love of the other but of the self. We must forgive ourselves as well as others in order to be whole and healed.”

Effect of Forgiveness on Health: The sum total of our health is a complex formula that differs slightly for each one of us.  Those of us with a progressive neurodegenerative disorder like Parkinson’s increases the complexity of this life-equation.  Thus, dealing with the axis defined by forgiveness/unforgiveness in the matter of health (both mental and physical) clearly could complicate our health.  Truly we need to add forgiveness as a filter to our life-lens; the benefits from this addition should favor our health in the long-run.

“If we all hold on to the mistake, we can’t see our own glory in the mirror because we have the mistake between our faces and the mirror; we can’t see what we’re capable of being. You can ask forgiveness of others, but in the end the real forgiveness is in one’s own self.” Maya Angelou

B Vitamins (Folate, B6, B12) Reduce Homocysteine Levels Produced by Carbidopa/Levodopa Therapy

“The excitement of vitamins, nutrition and metabolism permeated the environment.” Paul D. Boyer

“A substance that makes you ill if you don’t eat it.” Albert Szent-Gyorgy

Introduction: Claire McLean, an amazing-PT who is vital to my life managing my Parkinson’s, posted a very interesting article about the generation of homocysteine from the metabolism of levodopa to dopamine in the brain. Here is the article:

Screen Shot 2017-08-15 at 12.23.36 PM

This was all a very new concept to me. And as an ‘old-time’ biochemist by training, it led me down a trail of wonderful biochemical pathways and definitely a story worth retelling  for anyone taking carbidopa/levodopa.  Excessive generation of homocysteine leads to something called hyper-homocysteinuria, which is very detrimental to the cardiovascular system and even the neurological system.  Over time this could lead to a depletion of several B vitamins, which themselves would have biochemical consequences. This post is about the supplementation with a complex of B vitamins (including a cautionary note) during long-term therapy with carbidopa/levodopa.

“There are living systems; there is no ‘living matter’.” Jacques Monod

A reminder about Parkinson’s, dopamine and carbidopa/levodopa:  Someone with Parkinson’s  has reduced  synthesis of dopamine, an essential neurotransmitter produced by the substantia nigra of the midbrain region. A common medical treatment for Parkinson’s is the replacement of dopamine with its immediate precursor levodopa. Here are some of the key aspects regarding use of carbidopa/levodopa for treating Parkinson’s:

  1. Dopamine does not make it through the blood brain barrier to get to the brain;
  2. Levodopa (also known as L-3,4,-dihydroxyphenylalanine) is an amino acid that can cross the blood brain barrier and then be converted to dopamine;
  3. In the G.I. tract and the bloodstream, levodopa can be converted to dopamine by an enzyme named aromatic-L-amino-acid decarboxylase (DOPA decarboxylase or DDC),  which reduces the amount of levodopa that reaches the brain;
  4.  Carbidopa is a small molecule that prevents DOPA decarboxylase from converting levodopa to dopamine;
  5.  Carbidopa cannot pass through the blood brain barrier;
  6.  The “gold standard” treatment for Parkinson’s is a combination of carbidopa/levodopa, these drugs are commonly known as Sinemet, Sinemet CR, and Parcopa;
  7.  To review, we ingest carbidopa/levodopa, the carbidopa inhibits tissue enzymes that would break down the levodopa, this allows the levodopa to reach the blood-brain barrier, and then get converted to dopamine in the brain.
  8. Important side-note: Levodopa is an amino acid that crosses the blood brain barrier through a molecular amino acid transporter that binds amino acids.  Thus, eating and digestion of a protein-rich meal (also to be broken down to amino acids) either before or with your carbidopa/levodopa dose would competitively lower transport of levodopa across the blood brain barrier.  You should have been advised to take your carbidopa/levodopa doses (i) on an empty stomach, (ii) ~1 hr before eating or (iii) ~1-2 hr after eating (assuming you can tolerate it and the drug doesn’t cause nausea); this would insure your dose of levodopa gets across the blood brain barrier.

Here are the structures of the main players (top-left panel is levodopa; top-right panel is carbidopa; and the most commonly used dose is 25/100 immediate release carbidopa-levodopa (tablet with 25 mg carbidopa and 100 mg levodopa) on the bottom panel.

“The quality of your life is dependent upon the quality of the life of your cells. If the bloodstream is filled with waste products, the resulting environment does not promote a strong, vibrant, healthy cell life-nor a biochemistry capable of creating a balanced emotional life for an individual.” Tony Robbins

What’s the big deal about homocyteine (Hcy)?  Homocysteine is a sulfur-containing amino acid formed by demethylation of the essential amino acid methionine. Methionine is first modified to form S-adenosylmethionine (SAM), the direct precursor of Hcy,  This is important because SAM serves as a methyl-group “donor” in almost all biochemical pathways that need methylation (see figure below).  There are pathways that Hcy follows; importantly, the B vitamins of B6, B12 and folic acid are required for proper recycling/processing of Hcy.   An abnormal increase in levels of Hcy says that some disruption of this cycle has occurred.     Elevated Hcy is associated with a wide range of clinical manifestations, mostly affecting the central nervous system. Elevated Hcy has also been associated with an increased risk for atherosclerotic and thrombotic vascular diseases.  The mechanism for how Hcy damages tissues and cells remains under study; however, many favor the notion that excess Hcy increases oxidative stress.  As you might see why from the figure below, Hcy concentrations may increase as a result of deficiency in folate, vitamin B6 or B12. To recap, Hcy is a key biochemical metabolite focused in the essential methyl-donor pathway, whereby successful utilization of Hcy requires a role for complex B vitamins.  By contrast,  there is substantial evidence for a role of elevated Hcy as a disease risk factor for the cardiovascular and central nervous systems.

SAM+HCY


“We need truth to grow in the same way that we need vitamins, affection and love.” Gary Zukav

Sustained use of carbidopa/levodopa can result in elevated levels of homocysteine: As shown below, one of the reactions on levodopa involves methylation to form a compound named 3-O-methyldopa (3-OMD).   The reaction involves the enzyme catechol-O-methyl-transferase (COMT) and requires SAM as the methyl group donor. There is evidence that plasma Hcy levels are higher in carbidopa/levodopa-treated Parkinson’s patients when compared to controls and untreated Parkinson’s patients.  Interpretation of these results suggest the elevated Hcy levels is due to the drug itself and not from Parkinson’s.

Levodopa-3MO

B vitamins (folate, B6, B12) reduce homocysteine produced by carbidopa/levodopa therapy:   Based on the cycle and loops drawn below, they are not strictly one-way in  that theoretically you can drive the reaction in the reverse direction by using an excess amount of folate (NIH fact sheet, click here), vitamin B6 (NIH fact sheet, click here) and vitamin B12 (NIH fact sheet, click here) to reduce levels of Hcy. Folate supplementation was  previously found to reduces Hcy levels when used to treat an older group of people with vascular disease. Using the scheme depicted below as given in the slideshow there are four points I’d like to make:

  1. One might envision the brain is constantly processing a very small amount of levodopa to dopamine throughout the day. By contrast, we take 100’s of         milligram quantities of levodopa several times a day almost as if  we are giving ourselves a bolus of the precursor that reaches the brain. This scheme suggests that L-DOPA + SAM by COMT will produce Hcy; Over time ↑Hcy levels would be generated, leading to hyper-Hcy. Implied by hyper-Hcy is the consumption of B vitamins like folate, B12 and B6; deficiency of these vitamins would contribute to the body being unable to metabolize the excess Hcy.
  2. The folate/vitamin B12 cycle is crucial for DNA synthesis in our body.  This cycle verifies the essential role of folate and vitamin B12 in our diet and demonstrates their function in a key biochemical pathway. This also suggests that making too much Hcy could potentially consume both folate and B12, which would be detrimental to you. By contrast, the cycle also implies that by taking excess  folate and vitamin B12 you might drive the reaction the other direction and reduce the amount of Hcy generated,  and preserve the biochemical integrity of the cycle.
  3.  The processing of HCy is somewhat dependent on vitamin B6.  In the presence of excess Hcy you would consume the vitamin B6 ; however, the cycle also implies in the presence of an excess of vitamin B6 would allow the processing of Hcy further downstream.
  4.  Finally, unrelated to the B vitamins, the addition of N-Acetyl-cysteine (NAC) to the pathway would generate glutathione, which would help consume the excess Hcy  and also generate a very potent antioxidant compound.

“1914…Dr. Joseph Goldberger had proven that (pellagra) was related to diet, and later showed that it could be prevented by simply eating liver or yeast. But it wasn’t until the 1940’s…that the ‘modern’ medical world fully accepted pellagra as a vitamin B deficiency.” G. Edward Griffin

Beware of taking a huge excess of vitamin B6 in the presence of carbidopa/levodopa, a cautionary tale: I started taking a supplement that had relatively large amounts of complex B vitamins  (specifically the one labeled number two below) had 100% (400 mcg) folate, 1667% (100 mcg) vitamin B12 and 5000% (100 mg) of vitamin B6 (based on daily requirement from our diet).   Over a period of several days I started feeling stiffer, weaker as if  my medicine had stopped treating my Parkinson’s. I especially noticed it one day while playing golf because I had lost significant yardage on my shots, I was breathing heavily, and I was totally out of sync with my golf swing.  Just in general, my entire body was not functioning well.  Timing wise, I was taking the complex B vitamin pill with my early morning carbidopa/levodopa pill on an empty stomach. Something was suddenly (not subtly) wrong with the way I was feeling, and the only new addition to my treatment strategy was this complex B  vitamin pill. There had to be an explanation.

I went home and started thinking like a biochemist, started searching the Internet as an academic scientist, and found the answer in the old archives of the literature.  The older literature says taking more than 15 mg of vitamin B6 daily could compromise the effectiveness of carbidopa to protect levodopa from being activated in the tissues. Thus, I may have been compromising at least one or more doses of levodopa daily by taking 100 mg of vitamin B6 daily.  Let me further say I found that the half-life of vitamin B6 was 55 hours; furthermore, assuming 3L of plasma to absorb the vitamin B6, and a daily dose of 100 mg I plotted the vitamin B6 levels in my bloodstream. The calculation is based on a simple, single compartment elimination model assuming 100% absorbance that happens immediately. The equation is: concentration in plasma (µg/ml vitamin B6) = dose/volume * e^(-k*t) :

And further inspection of the possible reaction properties between vitamin B6, carbidopa and even levodopa suggests that vitamin B6 could be forming a Schiff Base, which would totally compromise the ability of either compound to function biologically (this is illustrated below).   And I should have known this because some of my earliest publications studied the binding site of various proteins and they were identified using vitamin B6 modifying the amino groups of the proteins (we were mapping heparin-binding sites):

Church, F.C., C.W. Pratt, C.M. Noyes, T. Kalayanamit, G.B. Sherrill, R.B. Tobin, and J.B. Meade (1989) Structural and functional properties of human α-thrombin, phosphopyridoxylated-α-thrombin and γT-thrombin: Identification of lysyl residues in α-thrombin that are critical for heparin and fibrin(ogen) interactions.  J. Biol. Chem. 264: 18419-18425.

“…The Chinese in the 9th century AD utilized a book entitled The Thousand Golden Prescriptions, which described how rice polish could be used to cure beri~beri, as well as other nutritional approaches to the prevention and treatment of disease. It was not until twelve centuries later that the cure for beri~beri was discovered in the West, and it acknowledged to be a vitamin B-1 deficiency disease.” Jeffrey Bland

To take or not to take, complex B vitamin supplementation:  I literally have been writing and working on this post since July; it started as a simple story about the use of complex B vitamins to reduce homocysteine levels as a consequence of chronic carbidopa/levodopa use to manage Parkinson’s.   If you eat a good healthy diet you’re getting plenty of B vitamins. Do you need mega-doses of complex B vitamins? My cautionary note described taking very large amounts of vitamin B6 may be compromising both carbidopa and/or levodopa. You should talk with your Neurologist because it’s straightforward to measure folate, vitamin B6 and B12, and homocysteine levels to see if they are in the normal range if you are taking carbidopa/levodopa. The hidden subplot behind the story is the growing awareness and importance of managing homocysteine levels and also knowing the levels of folate, B6 and B12 to help maintain your neurological health.  Bottom line, if you need it, take a multiple vitamin with only 100 to 200% of your daily need of vitamin B6 (what is shown in panel three and four above). And please be careful if you decide to take a larger dose of vitamin B6 (between 10-100 mg/day).

“A risk-free life is far from being a healthy life. To begin with, the very word “risk” implies worry, and people who worry about every bite of food, sip of water, the air they breathe, the gym sessions they have missed, and the minutiae of vitamin doses are not sending positive signals to their cells. A stressful day sends constant negative messaging to the feedback loop and popping a vitamin pill or choosing whole wheat bread instead of white bread does close to zero to change that.” Deepak Chopra

Diet and Dementia (Cognitive Decline) in the Aging

“When diet is wrong medicine is of no use. When diet is correct medicine is of no need.’’ Ancient Ayurvedic Proverb

‘‘What is food to one man may be fierce poison to others.’’ Lucretius (99 B.C.-55 BC).

Précis: Last month in London, England, at the Alzheimer’s Association International Conference (AAIC) 2017, there were several presentations focused on diet and the link with dementia/cognitive decline in the elderly population.  Two reports described the effect of specific diets [Mediterranean, DASH (Dietary Approaches to Stop Hypertension), MIND (Mediterranean-DASH Intervention for Neurodegenerative Delay), and NPDP (Nordic Prudent Dietary Pattern)] to maintain cognitive function in the aging population. In another study, the MIND diet was shown to reduce dementia in the women from the Women’s Health Initiative Memory Study (WHIMS).  Finally, it was shown that either the absence or excess of certain vitamins, minerals and other key nutrients could promote neuro-inflammation, which would be detrimental to the brain. This post reviews elements of these presentations.

“One should eat to live, not live to eat.” Moliere

A Healthy Body and Brain Combine Diet, Life-style, and Attitude: It is easy to say what it takes to be healthy; however, approaching/achieving/accomplishing it takes a concerted effort. In a minimal sense, achieving a healthy body and brain unites an efficient diet, an effective lifestyle, and a positive attitude.  Thus, a healthy body and brain requires a collective approach to living properly (and it helps to have good genes).

“Take care of your body. It’s the only place you have to live.” Jim Rohn

Inflammation and Parkinson’s: One of the many suggested causes of Parkinson’s is neuro-inflammation (see figure below).  The impact of diet promoting inflammation and cognitive decline in the aging population got my interest.  The combination of eating too much of ‘bad’ foodstuff with too little of some ‘good’ food components somehow promotes neuro-inflammation that contributes to the development of dementia. If the goal of my blog is related to Parkinson’s, what is the goal of this particular post? To present the notion that detrimental effects of neuro-inflammation could diminish brain function. And it’s this ‘possibility’ that makes the story relevant to this blog because neuro-inflammation is linked to the development of both Alzheimer’s and Parkinson’s.  Therefore, the specific pathway to how you develop that inflammation of the brain is relevant and an important topic.

“Tell me what you eat, and I will tell you who you are.” Jean Anthelme Brillat-Savarin

Diet Linked to Neuro-inflammation: There’s an old phrase “You Are What You Eat”, which simply means it’s critical to eat good food in order to stay healthy and fit. Building on solid evidence that eating well is brain healthy, researchers are beginning to explore mechanisms through which dietary mechanisms may influence cognitive status and dementia risk. Dr. Gu and colleagues (Columbia University, New York) examined whether an inflammation-related nutrient pattern (INP) was associated with changes in cognitive function and structural changes in the brain. Gu, Y., et al. (An Inflammatory Nutrient Pattern Is Associated Both Structural and Cognitive Measures of Brain Aging in the Elderly) presented a follow-up study to earlier work using brain scans (MRI) combined with levels of inflammatory makers [C-reactive protein (CRP) and interleukin-6 (IL-6)] and cognitive function studies of >300 community-dwelling elderly people who were non-demented.

They created what was termed an “InflammatioN-related Pattern (INP) where increased levels of CRP and IL-6 were found in participants with low dietary intake of omega-3 polyunsaturated fatty acids, calcium, folate and several water- and fat-soluble vitamins (including B1, B2, B5, B6, D, and E) and increased consumption of cholesterol, beta-carotene and lutein. The INP was derived from a 61-item food frequency questionnaire that the study participants answered about their food intake during the past year. Study participants with this ‘INP-diet-pattern’ also had poorer executive function scores and smaller total brain gray matter volume compared to study participants with a healthier diet.  The strength of the study was the scientific precision and methodology; however, it was not directly comparing one diet to another.  Further studies are needed to verify the role of diet to induce neuro-inflammation-related changes in dementia (cognitive health).  Furthermore, mechanistic insight is needed to understand how a diet with either an absence or an excess of certain nutritional components promotes neuro-inflammation to alter brain function and structure. Their results imply that a poor diet promotes dementia and smaller brain volume in the aging brain through a neuro-inflammatory process.

“The food you eat can either be the safest and most powerful form of medicine, or the slowest form of poison.” Ann Wigmore

What is Good for Your Heart is Good for Your Brain: The Mediterranean diet, a diet of a type traditional in Mediterranean countries, characterized especially by a high consumption of vegetables and olive oil and moderate consumption of protein, is usually thought to confer healthy-heart benefits. The DASH (Dietary Approaches to Stop Hypertension) diet was developed to help improve cardiovascular health, especially hypertension. The DASH diet is simple: eat more fruits, vegetables, and low-fat dairy foods; cut back on foods that are high in saturated fat, cholesterol, and trans fats; eat more whole-grain foods, fish, poultry, and nuts; and limit sodium, sweets, sugary drinks, and red meats. Neurologists have merged the two diets, creating the Mediterranean-DASH Intervention for Neurodegenerative Delay, or MIND diet; testing the hypothesis that if it’s good for the heart it will be good for the brain.   The MIND diet is gaining attention for its potential positive effects on preserving cognitive function and reducing dementia risk in older individuals. In an earlier study, Morris et al. (Alzheimer’s Dement. 2015; 11:1015-22) found that  individuals on the MIND diet showed less cognitive decline as they aged.

Moving to 2017, Dr. McEvoy and colleagues (University of California, San Francisco) studied ~6000 older adults in the Health and Retirement Study. They showed that the study participants who followed either the MIND or the Mediterranean diets were more likely to maintain strong cognitive function in old age (McEvoy, C., et al. Neuroprotective Dietary Patterns Are Associated with Better Cognitive Performance in Older US Adults: The Health and Retirement Study). Their results also showed that study participants with either of these healthier diets had significant retention of cognitive function.

The doctor of the future will no longer treat the human frame with drugs, but rather will cure and prevent disease with nutrition.” Thomas A. Edison

The Nordic Prudent Dietary Pattern (NPDP) Protects Cognitive Function: The NPDP includes both more frequent and less frequent food consumption categories: More frequent consumption of non-root vegetables, apple/pears/peaches, pasta/rice, poultry, fish, vegetable oils, tea and water, and light to moderate wine intake; Less frequent intake of root vegetables, refined grains/cereals, butter/margarine, sugar/sweets/pastries, and fruit juice. Dr. Xu and colleagues (Karolinska Institute, Stockholm, Sweden) studied the relationship of diet to cognitive function in >2,200 dementia-free community-dwelling adults in Sweden (Xu,W., et al. Which Dietary Index May Predict Preserved Cognitive Function in Nordic Older Adults). During six years of evaluation, they reported that study participants with moderate loyalty to the NPDP had better cognitive function compared to study participants who deviated more frequently from the NPDP.  The scientists noted that, in the Scandinavian population studied, the NPDP was better at maintaining cognitive function compared to other diets (Mediterranean, MIND, DASH, and Baltic Sea).

“The trouble with always trying to preserve the health of the body is that it is so difficult to do without destroying the health of the mind.” Gilbert K. Chesterton

Women on the MIND Diet are Less Likely to Develop Dementia: Dr. Hayden and colleagues (Wake Forest School of Medicine, Winston-Salem, North Carolina) studied diet and dementia in >7,000 participants from the Women’s Health Initiative Memory Study (WHIMS) (Hayden, K., et al. The Mind Diet and Incident Dementia, Findings from the Women’s Health Initiative Memory Study).   The study showed that older women who followed the MIND diet were less likely to develop dementia. These results were obtained by stratification of the WHIMS  participants from very likely to very unlikely to adhere to the MIND diet; they were  assessed for almost 10 years.  Their results imply that it may not require drastic diet changes to help preserve the aging brain.

“It’s not about eating healthy to lose weight. It’s about eating healthy to feel good.” Demi Lovato

Diet and Dementia in the Aging Brain: Four different studies with similar results; diet can  influence dementia and cognitive function in the aging brain.  The single most important finding in these studies was simply that a good diet helps maintain a healthy brain. Strong evidence was presented in three of the studies that the Mediterranean, the MIND and NPBP are excellent diets to help maintain cognitive function as we age.  Mechanistic studies to further demonstrate the link of dietary components with an increase in neuro-inflammation  would be most interesting. A confounding issue is that overall health and a healthy brain are more than just diet alone.  To reduce the chance of cognitive decline and dementia, it’s important to remember as we get older to protect our brain by eating well, exercise regularly, and exercise our brain by becoming lifelong learners (see Word Cloud below).

10 “P-Words” That Will Help Your Career Even in the Presence of Parkinson’s

“Enjoy the journey, enjoy every moment, and quit worrying about Winning and losing.” Matt Biondi

“Enjoy the journey as much as the destination.”  Marshall Sylver

Introduction:  It has been a month since my last blog post.  Trips to Arizona, California, Alabama, and Florida consumed much of the month.  I spent time with relatives, dear old friends, and played many rounds of golf.  The spring semester was most enjoyable but also it was quite consumptive.  Life-changes.  And I just needed a short break.

10 “P-Words” That Will Help Your Career:  I found a piece of paper recently that had a bunch of hand-written words that started with the letter “P”.  These words were all focused in the mindset of how to achieve/sustain success in the world of medical academics/research in a university setting.  Use these P-words while you advance/survive/navigate/succeed through your career.

At various times during your career, some words may take precedence depending on the situation.  However, if you consider the words in the form of a melody, they will all significantly contribute to the symphony of your work-life.  There is no doubt there are many other words we could cite that help you navigate work, that allow you to succeed in your career.  My list is just a start or an attempt to help you focus your energies with the goal of advancement and happiness in your work world. May this list help you focus and achieve further in your professional career.

  1. Passionate (Capable of, having, or dominated by powerful emotions):
    “There is no greater thing you can do with your life and your work than follow your passions – in a way that serves the world and you.” Richard Branson
  2. Patient (Tolerant; understanding):
    “Never cut a tree down in the wintertime. Never make a negative decision in the low time. Never make your most important decisions when you are in your worst moods. Wait. Be patient. The storm will pass. The spring will come.”  Robert H. Schuller
  3. Perseverance (Continued steady belief or efforts, withstanding discouragement or difficulty):
    “Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.”  Thomas A. Edison
  4. Persistent (Continuance of an effect after the cause is removed):
    “You just can’t beat the person who never gives up.” Babe Ruth
  5. Positivity (Characterized by or displaying certainty, acceptance, or affirmation):
    “There is little difference in people, but that little difference makes a big difference. The little difference is attitude. The big difference is whether it is positive or negative.”  W. Clement Stone
  6. Power (The ability or capacity to act or do something effectively):
    “You must try to make the most of all that comes but also don’t forget to learn a lot of all that goes.” William C. Brown
  7. Prepared (To make ready beforehand for a specific purpose):
    “The best preparation for good work tomorrow is to do good work today.” Elbert Hubbard
  8. Principled(s) (Based on, marked by, or manifesting principle):
    “I wish I had been wiser. I wish I had been more effective, I wish I’d been more unifying, I wish I’d been more principled.” Bill Ayers
  9. Productive (Effective in achieving specified results):
    “Start by doing what’s necessary; then do what’s possible; and suddenly you are doing the impossible.”  Francis of Assisi
  10. Purposeful (Determined; resolute):
    “All life is a purposeful struggle, and your only choice is the choice of a goal.”  Ayn Rand

The 10 “P-Words” Could Assist the Journey (definitions from the Free Dictionary): You may have a different definition for these words and you may know of better quotes given for each word. Good!  The balance, guidance and focus of each word as they are applied to work is what matters.

I remember reading in 1989 “The 7 Habits of Highly Effective People” by Stephen R. Covey, and found it useful.  But in hindsight, my mind functions in a simpler more scientific manner, words work better to focus my mind than did chapters and detailed stories.  Covey has sold more than 25 million copies of his book; clearly his description his ability to provide a powerful narrative was most successful – I did learn a lot from his book.  However, this list of words simply spells out a way to help coordinate the complexity of a career.

The 10 “P-Words” Work in the Presence of Parkinson’s:  I have had Parkinson’s for the past 5-6 years, and I am still working full-time.  No doubt Parkinson’s affects each person differently; it allows some to continue to work and others must stop.   Some of the effects of Parkinson’s on my work: I type slower than I used to, stiffness takes over if I sit too long, and at times I lose my focus.  I remain hopeful that even under the influence of Parkinson’s I can stay focused on education and science until its time.  There are many great things influencing my life and work.   I want to be in the driver’s seat to get to that point when I can say “I’ve done enough!”. Simply put, I refuse to surrender to Parkinson’s. If you are still working, I’m happy for you.  Probably for those of us with Parkinson’s, the key P-words are to stay positive, remain patient, always persevere, and never lose your passion.

“When you are a young person, you are like a young creek, and you meet many rocks, many obstacles and difficulties on your way. You hurry to get past these obstacles and get to the ocean. But as the creek moves down through the fields, it becomes larges and calmer and it can enjoy the reflection of the sky. It’s wonderful. You will arrive at the sea anyway so enjoy the journey. Enjoy the sunshine, the sunset, the moon, the birds, the trees, and the many beauties along the way. Taste every moment of your daily life.”  Nhat Hanh

The Yack on NAC (N-Acetyl-Cysteine) and Parkinson’s

“Once you choose hope, anything’s possible.” Christopher Reeve

“Hope is like a road in the country; there was never a road, but when many people walk on it, the road comes into existence.” Lin Yutang

Introduction: N-Acetyl-Cysteine (or N-acetylcysteine, usually abbreviated NAC and frequently pronounced like the word ‘knack’) is an altered (modified by an N-acetyl-group) form of the sulfur-containing amino acid cysteine (Cys).  NAC is one of the building blocks for the all important antioxidant substance glutathione (GSH).   GSH is a powerful reagent that helps cells fight oxidative stress.  One of the putative causes of Parkinson’s is oxidative stress on dopamine-producing neurons (see figure below). This post summarizes some of the biochemistry of NAC and GSH.  Furthermore, NAC may provide some neuroprotective benefit as a complementary and alternative medicine (CAM) approach to treating Parkinson’s.

“Losing the possibility of something is the exact same thing as losing hope and without hope nothing can survive.” Mark Z. Danielewski

 Glutathione (GSH):  GSH is a 3-amino acid substance (tripeptide) composed of Cys linked to glutamate (Glu) and followed by glycine (Gly). NAC would need to be de-acetylated to provide Cys and that would feed in to the reaction synthesis. Importantly, Cys is the rate limiting reactant, which means without adequate amounts of Cys you do not make GSH.   The schematic below gives the orientation and order of addition of the three amino acid components to give you GSH.

NACtoGSH

There are two advantages of NAC over Cys for making GSH: (i) the sulfhydryl group of NAC remains reduced (that is as an SH group) more so than the SH group of Cys; and (ii) the NAC molecule appears to transport itself through cell membranes much more easily than Cys.  The reduced (i.e.,  free SH group) form of GSH, once synthesized within the cell, has several key functions that range from antioxidant protection to protein thiolation to drug detoxification in many different tissues.   The key function of GSH is to provide what is known as “reducing equivalents” to the cell, which implies an overall key antioxidant effect.

The schematic below shows NAC transport from extracellular to intracellular (inside the cell), and the primary reactions for detoxification and thiolation from GSH. Implied by this figure below is that GSH is not easily transported into the cell. Furthermore, in a more toxic/hostile environment outside of the cell, you can easily oxidize 2 GSH molecules to become GSSG (the reduced SH group gets oxidized to form an S-S disulfide bond) and GSSG does not have the antioxidant effect of GSH.   However, inside the cell, GSH is a very potent antioxidant/detoxifying substance. And the beauty of being inside the cell, there is an enzyme called GSH-reductase that regenerates GSH from GSSG.

Rushworth-NAC.review-4.2

To recap and attempt to simplify what I just said, NAC gets delivered into a cell, which then allows the cell to generate intracellular GSH.  The presence of intracellular GSH gives a cell an enormous advantage to resist potentially toxic oxidative agents. By contrast, extracellular GSH has a difficult path into the cell; and is likely to be oxidized to GSSG and rendered useless to help the cell.

“Just remember, you can do anything you set your mind to, but it takes action, perseverance, and facing your fears.”  Gillian Anderson

One of many biological functions of NAC:   Perhaps the most important medical use of NAC is to help save lives in people with acetaminophen toxicity, in which the liver is failing.  How does NAC do this?  Acetaminophen is sold as Tylenol.  It is also added to compounds that are very important for pain management ()analgesics), including Vicodin and Percocet. Acetaminophen overdose is the leading cause of acute liver failure in the USA.   This excess of acetaminophen rapidly consumes the GSH in the liver, which then promotes liver death.  NAC quickly restores protective levels of GSH  to the liver, which hopefully reverses catastrophic liver failure to prevent death.

Systemically, when taken either orally or by IV injection, NAC would have 2 functions.  First, NAC replenishes levels of Cys to generate the intracellular antioxidant GSH (see schemes above).  Second, NAC has been shown to regulate gene expression of several pathways that link oxidative stress to inflammation.  Since the primary goal of this post relates to NAC as a CAM in Parkinson’s, I will not expand further on the many uses of NAC in other disease processes.  However, listed at the end are several review articles detailing the numerous medicinal roles of NAC.

“Love, we say, is life; but love without hope and faith is agonizing death.” Elbert Hubbard

Use of NAC as a CAM in Parkinson’s:   This is what we know about oxidative stress in Parkinson’s and the potential reasons why NAC could be used as a CAM in this disorder, it goes as follows  (it’s also conveniently shown in the figure at the bottom):

1. Substantia nigra dopamine-producing neurons die from oxidative stress, which can lead to Parkinson’s.

2.What is oxidative stress? Oxidative stress happens when your cells in your body do not make/have enough antioxidants to reduce pro-oxidants like free radicals. Free radicals cause cell damage/death when they attack proteins/cell membranes.

3.We speak of oxidative stress in terms of redox imbalance (which means the balance between increased amounts of oxidants or  decreased amounts of antioxidants).

4.Glutathione (GSH) is a key substance used by cells to repair/resist oxidatively damaged cells/proteins.

5.”Forces of evil” in the brain that make it difficult to resist oxidative stress:  decreased levels of GSH,  increased levels of iron and  increased polyunsaturated fatty acids.

6.Extracellar GSH cannot be transported easily into neurons, although there is evidence GSH gets past the blood brain barrier;

7.N-acetyl Cysteine (NAC), is an anti-oxidant and a precursor to GSH.  NAC gets through the blood brain barrier and can also be transported into neurons.

8.Cysteine is the rate-limiting step for GSH synthesis (NAC would provide the cysteine and favor synthesis of GSH).

9.Animal model studies have shown NAC to be neuroprotective.

10. Recent studies have shown NAC crosses the human blood brain barrier and may be a useful PD-modifying therapy.

Scientific and clinical support for NAC in treating Parkinson’s: Content presented here is meant for informational purposes only and not as medical advice.  Please remember that I am a basic scientist, not a neurologist, and any use of these compounds should be thoroughly discussed with your own personal physician. This is not meant to be an endorsement  because it would be more valuable and important for your neurologist to be in agreement with the interpretation of these papers.

To evaluate the use of NAC in Parkinson’s, Katz et al. treated 12 patients with Parkinson’s with oral doses of NAC twice a day for two days.   They studied three different doses of 7, 35, and 70 mg per kilogram. For example, in a person weighing 170 pounds, from a Weight Based Divided Dose Calculator (click here), this would be 540, 2700, and 5400 mg/day of NAC for 7, 35, and 70 mg/kg, respectively. Using cerebral spinal fluid (CSF), they measured levels of  NAC, Cys, and GSH at baseline and 90 minutes after the last dose. Their results showed that there was a dose-dependent range of NAC as detected by CSF. And they concluded that oral administration of NAC produce biologically relevant CSF levels of NAC at the three doses examined; the doses of oral NAC were also well-tolerated.  Furthermore, the patients treated with NAC had no change in either motor or cognitive function. Their conclusions support the feasibility of using oral NAC as a CAM therapy for treatment of Parkinson’s.

In a separate study, Monti at al  presented some preliminary evidence for the use of NAC in Parkinson’s. The first part of their study consisted of a neuronal cell system that was pre-treated with NAC in the presence of the pesticide rotenone as a model of Parkinson’s.   These results showed that with NAC there was more neuronal cell survival after exposure to rotenone compared to the rotenone-treated cells without NAC. The second part of the study was a small scale clinical evaluation using NAC in Parkinson’s. These patients were randomized and given either NAC or nothing and continued to use their traditional medical care. The patients were evaluated at the start and after three months of receiving NAC; they measured dopamine transporter binding and  performed the unified Parkinson’s disease rating scale  (UPDRS) to measure clinical symptoms. The clinical study revealed an increase in dopamine transporter binding in the NAC treatment group and no measurable changes in the control group. Furthermore UPDRS scores were significantly improved in the NAC treatment group compared to the control patient group.   An interesting feature of this study was the use of pharmaceutical NAC, which is an intravenous (IV) medication and they also used 600 mg NAC tablets. The dose used was 50 mg per kg mixed into sterile buffer and infused over one hour one time per week. In the days they were not getting the IV NAC treatment, subjects took 600 mg NAC tablets twice per day.

 Okay, what did I just say? I will try to summarize both of these studies in a more straightforward manner.   The results above suggest that NAC crosses the blood brain barrier and does offer some anti-oxidative protection. In one study, this was shown by increased levels of both GSH and Cys dependent on the NAC dose. In another study, they directly measured dopamine transporter binding, which was increased in the presence of NAC. In the second study using a three month treatment strategy with NAC, there was a measurable positive effect on disease progression as measured by UPDRS scores.  

“Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.” Thomas A. Edison

Potential for NAC in treating Parkinson’s: Overall, both studies described above suggest the possibility that NAC may be useful in treating Parkinson’s. However, in both cases these were preliminary studies that would require much larger randomized double-blind placebo-controlled trials to definitively show a benefit for using NAC in treating Parkinson’s. On a personal note, I have been taking 600 mg capsules of NAC three times a day for the past year with the hope that it is performing the task as outlined in this post. Using information from the first study that would be a NAC dose of 24 mg per kilogram body weight. In conclusion, the information described above suggests that NAC may be useful in regulating oxidative stress, one of the putative causes of Parkinson’s. As with all studies, time will tell if ultimately there is a benefit for using NAC in Parkinson’s.

“I am not an optimist, because I am not sure that everything ends well. Nor am I a pessimist, because I am not sure that everything ends badly. I just carry hope in my heart. Hope is the feeling that life and work have a meaning. You either have it or you don’t, regardless of the state of the world that surrounds you. Life without hope is an empty, boring, and useless life. I cannot imagine that I could strive for something if I did not carry hope in me. I am thankful to God for this gift. It is as big as life itself.” Vaclav Havel
