|MaryAnn, my partner, and Emma Alice, one of our grandchildren. Both are alive thanks to modern chemistry, loving family, great doctors and nurses, and a hearty dose of prayer. They also motivate me to get with the program.|
A: It's a progressive, degenerative disease of the central nervous system and is characterized by impaired movement [e.g. the classical hand tremors] and other problems involving non-motor functions [e.g. swallowing, speech, cognitive functions]. I want to stress that I am not a physician, that this information derives from my years living with PD. We have what works as neurotransmitters in our brains: dopamine. For whatever reason--age, exposure, genetics, other medications--our dopamine, to put it in lay terms, quits working. As my neurotransmitters misfire, I experience the symptoms of Parkinson's. Dopamine agonists, which I take in the form of cardidopa/levadopa, bind to the dopamine receptors and enable proper firing.
Q: How did you get PD? Did anyone in your family have it?
A: I don't know and no. That question came up at the symposium. Is it nature or nurture, stress, genetics, the environment? Michael J. Fox got it at a very early age, and there is some indication that early onset may have more of a genetic component than late. Nobody in my family had PD, and my parents died in their late 90s. I was, however, exposed to toxic environments all my life. I grew up in the otherwise perfect city of Oak Ridge, TN, where we built part of the atomic bomb, but the beautiful environment and lots of residents and workers suffered various forms of cancer and neurological disorders. Then I spent 16 years safely ensconced in the academic life, but at 33 I fulfilled my life long dream of becoming a fireman (sic). Talk about hazardous environments! Did all of this cause PD? The answer is we don't know, but my body has been exposed to significant toxicity.
Q: How do you know you have PD?
A: Difficult question. In my case--and I am in no way trying to give medical advice--I developed tremors when I was 56. When I turned 60 (classical time for PD to manifest itself) worsening tremors sent me to my primary care physician. This is a man who saved MaryAnn's life, who is an absolute genius, and who really listens to and studies his patients. He looked very worried, prescribed Sinemet, and referred me to a new neurologist. At that point, my MRI showed nothing except a brain, which I was beginning to doubt. But my neurologist observed beginning rigidity, increasingly terrible tremors, legs that took on a life of their own, imbalance, falling, and, occasionally, the tell-tale shuffling walk.
Q: What is PD treatment?
A: I can only tell you what I do, although I know the meds I take are commonly prescribed for PD. I take Sinemet, which is Cardidopa/Levodopa, and Mirapex. There are other drugs with which I am not familiar, and there is also Deep Brain Stimulation. Then there is what's looking like the most significant variable in PD therapy--EXERCISE. And that's one motivation for this blog. If I tell people that I am going to do this more faithfully--and report on it--I have to do it.
This is my friend--Dopamine.
