Parkinson’s Disease Research: A Commentary from the Stands and the Playing Field

“You can have a very bad end with Parkinson’s, but on the other hand, you can be like me, because I’m lucky. I’m not having a bad end.” Margo MacDonald

“My age makes me think how valuable life is. How bad is something like Parkinson’s in relation to not having life at all?” Michael J. Fox

Introduction: Last month, together with Dr. Simon Stott and his team of scientists (The Science of Parkinson’s Disease), we co-published a historical timeline of Parkinson’s disease beginning with the description of the ‘shaking palsy’ from James Parkinson in 1817. My post entitled “Milestones in Parkinson’s Disease Research and Discovery” can be read here (click this link). The Science of Parkinson’s Disease post entitled “Milestones in Parkinson’s Disease Research and Discovery” can be read here (click this link).

We spent a lot of time compiling and describing what we felt were some of the most substantial findings during the past 200 years regarding Parkinson’s disease.  I learned a lot; truly amazing what has been accomplished in our understanding of  such a complex and unique disorder.  Simon posted a follow-up note entitled “Editorial: Putting 200 years into context” (click this link). I have decided to also post a commentary from the standpoint of (i) being someone with Parkinson’s and (ii) being a research scientist.

“Every strike brings me closer to the next home run.” Babe Ruth

Baseball: I want to use the analogy of a baseball game to help organize my commentary. Baseball fans sit in the stands and have fun watching the game, thinking about the strategy behind the game, eating/drinking, and sharing the experience with family/friends/colleagues.   Most baseball players begin playing early in life and the ultimate achievement would be to reach the major leagues. And this would usually have taken many years of advancing through different levels of experience on the part of the ballplayer. How does how this analogy work for me in this blog? Stands: I am a person-with-Parkinson’s watching the progress to treat and/or cure this disorder. Playing field: I am a research scientist in a medical school (click here to view my training/credentials).

“Never allow the fear of striking out keep you from playing the game!”  Babe Ruth

Observation from the stands:
I am a spectator like everyone else with Parkinson’s. I read much of the literature available online.  Like you, I think about my disorder; I think about how it’s affecting me every day of my life. Yes, I want a cure for this disease.  Yes, I’m rather impatient too.  I understand the angst and anxiety out there with many of the people with Parkinson’s. In reality, I would not be writing this blog if I didn’t have Parkinson’s. Therefore, I truly sense your frustration that you feel in the presence of Parkinson’s, I do understand.  Given below are examples of various organizations and ads and billboards in support of finding a cure for Parkinson’s.  Some even suggest that a cure must come soon.   However, the rest of my post is going to be dedicated to trying to explain why it’s taking so long; why I am optimistic and positive a cure and better treatment options are going to happen.  And it is partly based on the fact that there really are some amazing people working to cure Parkinson’s and to advance our understanding of this disorder.

“When you come to a fork in the road take it.” Yogi Berra

Observations from the playing field (NIH, war on cancer, research lab, and advancing to a cure for Parkinson’s):

National Institutes of Health (NIH) and biomedical research in the USA: Part of what you have to understand, in the United States at least, is that a large portion of biomedical research is funded by the NIH (and other federally-dependent organizations), which receives a budget from Congress (and the taxpayers). What does it mean for someone with Parkinson’s compared to someone with cancer or diabetes? The amount of federal funds committed to the many diseases studied by NIH-funded-researchers are partly divvied up by the number of people affected. I have prepared a table from the NIH giving the amount of money over the past few years for the top four neurodegenerative disorders, Alzheimer’s, Parkinson’s, amyotrophic lateral sclerosis (ALS), and Huntington’s Disease, respectively [taken from “Estimates of Funding for Various Research, Condition, and Disease Categories” (click here)]. And this is compared to cancer and coronary arterial disease and a few other major diseases. Without going into the private organizations that fund research, a large amount of money comes from the NIH. Unfortunately, from 2003-2015, the NIH lost >20% of its budget for funding research (due to budget cuts, sequestration, and inflationary losses; click here to read further).   Therefore,  it is not an overstatement to say getting  funded today by the NIH is fiercely competitive.  From 1986 to 2015, my lab group was supported by several NIH grants and fellowships  (and we also received funding from the American Heart Association and Komen for the Cure).


“In theory, there is no difference between theory and practice. But in practice, there is.” Yogi Berra

War against cancer: In 1971, Pres. Richard Nixon declared war against cancer and Congress passed the National Cancer Act.  This created a new national mandate “to support research and application of the results of research to reduce the incident, morbidity, and mortality from cancer.” Today, cancer is still the second leading cause of death in the USA; however, we’ve come such a long way to improving this statistic from when the Cancer Act was initiated.

Scientifically, in the 1970’s, we were just learning about oncogenes and the whole field of molecular biology was really in its infancy. We had not even started sequencing the human genome, or even of any organism.  We discovered genes that could either promote or suppress cellular growth.   We began to delineate the whole system of cell signaling and communications with both normal and malignant cells. We now know there are certain risk factors that allow us to identify people that may have increased risk for certain cancers. Importantly,  we came to realize that not all cancers were alike,  and it offered the notion to design treatment strategies for each individual cancer.  For example,  we now have very high cure rates for childhood acute leukemia and Hodgkin’s lymphoma and we have significantly improved survival statistics for women with breast cancer. Many might say this was a boondoggle and that we wasted billions of dollars  funding basic biomedical research on cancer; however, basic  biomedical research is expensive and translating that into clinical applications is even more expensive.  [ For a  very nice short review on cancer research please see the following article, it may be freely accessible by now: DeVita Jr, Vincent T., and Steven A. Rosenberg. “Two hundred years of cancer research.” New England Journal of Medicine 366.23 (2012): 2207-2214.]

“One of the beautiful things about baseball is that every once in a while you come into a situation where you want to, and where you have to, reach down and prove something.” Nolan Ryan

The biomedical research laboratory environment:  A typical laboratory group setting is depicted in the drawing below. The research lab usually consists of the lead scientist who has the idea to study a research topic, getting grants funded and in recruiting a lab group to fulfill the goals of the project.  Depending on the philosophy of the project leader the lab may resemble very much like the schematic below or may be altered to have primarily technicians or senior postdoctoral fellows working in the lab  (as two alternative formats). A big part of academic research laboratories is education and training the students and postdocs to go on to advance their own careers; then you replace the people that have left and you continue your own research.  Since forming my own lab group in 1986, I have helped train over 100 scientists in the research laboratory: 17 graduate students, 12 postdoctoral fellows, 17 medical students, and 64 undergraduates. The lab has been as large as 10 people and a small as it is currently is now with two people. People come to your lab group because they like what you’re doing scientifically and this is where they want to belong for their own further training and advancement.  This description is for an academic research  laboratory; and  I should also emphasize that many people get trained in federal government-supported organizations, private Pharma and other types of research environments that may differ in their laboratory structure and organizational format.


“Hitting is 50% above the shoulders.” Ted Williams

 In search of the cure for Parkinson’s:    First, I understand the situation you’re in with Parkinson’s because I’m living through the same situation.   But when people find out I’m a research scientist they always wonder why aren’t we doing more to find a cure, and I  hear the sighs of frustration and I see the anxiety in their faces. Second, the previous three sections are not meant to be an excuse for why there is still no cure for Parkinson’s. It is presented in the reality of what biomedical research scientists must undergo to study a topic.  Third, the experiments that take place in basic biomedical research laboratory may happen over weeks to months if successful. Taking that laboratory data to the clinic and further takes months and years to succeed if at all.   The section on cancer reminds me a lot of where we are going with Parkinson’s and trying to advance new paradigms in the treatment and curative strategies.  Professionally, I have even decided  to pursue research funding in the area of Parkinson’s disease.   Why not spend the rest of my academic career studying my own disease; in the least I can help educate others about this disorder. Furthermore, I can assure you from my reading and meeting people over the last couple of years, there are many hundreds of scientists and clinicians throughout this world studying Parkinson’s and trying to advance our understanding and derive a cure.  I see their devotion, I see their commitment to helping cure our disorder.

The science behind Parkinson’s is quite complicated. These complications suggest that Parkinson’s may be more of a syndrome rather than a disease. Instead of a one-size-fits-all like a disease would be classified; Parkinson’s as a syndrome would be a group of symptoms which consistently occur together.  What this might imply is that some treatment strategy might work remarkably well on some patients but have no effect on others. However, without a detailed understanding and advancement of what Parkinson’s really is we will never reach the stage where we can cure this disorder.

In a recent blog from the Science of Parkinson’s disease, Simon nicely summarized all the current research in 2017 in Parkinson’s disease (click here to read this post). To briefly summarize what he said is that there are multiple big Pharma collaborations occurring to study Parkinson’s.  There are more than 20 clinical trials currently being done in various stages of completion to prevent disease progression but also to try to cure the disorder.  From a search of the literature, there are literally hundreds of research projects going on that promise to advance our understanding of this disorder. With the last point, it still will take time to happen. Finally, I am a realist but I’m also optimistic and positive that we’re making incredible movement toward much better therapies, which will eventually lead to curative options for Parkinson’s.

And a final analogy to baseball and Parkinson’s, as Tommy Lasorda said “There are three types of baseball players: those who make it happen, those who watch it happen, and those who wonder what happens.”  I really want to be one of those scientists that help make it happen (or at least to help advance our understanding of the disorder).

“You can’t expect life to play fair with your heart or your brain or your health. That’s not the nature of the game we call life. You have to recognize the nature of the game and know that you can do your best to make the right choices, but life if going to do whatever the hell it pleases to you anyway. All you can control is how you react to whatever life throws at you. You can shut down or you can soar.” Holly Nicole Hoxter
