Q
An anonymous caregiver asked...
My Father was diagnosed with Parkinson's about 11 years ago after a bad fall. My Mother had pronounced hand tremors for many years but her doctor was never able to confirm or deny weather she,too, had Parkinson's. Both are gone now. As I approach my 52nd birthday, I am very concerned about my chances of developing this horrible disease. What are my chances of escaping this fate?

The question as to whether Parkinson disease is hereditary is quite complicated. Researchers now think that about 7 or 8 percent of patients with PD have a direct genetic link. See also:

This is much more likely to be the case if your parents had onset of Parkinson disease in their 40s or younger. Otherwise it is much less likely. For the remaining people with Parkinson disease, we think that there may be certain genes that put them at an increased risk of developing PD, and that these genes may interact with other genes and environmental factors such as pesticide exposure to result in Parkinson disease. Unless your parents were tested for the specific genes associated with PD, it is virtually impossible to tell you how likely you are to get PD, but genetic cases of PD remain by far in the minority of cases.

Your chances are actually pretty good but that is not based upon genetics but the apparent fact that PD often skips a generation or more even when familial.

A few years ago the percentage of PwP of genetic origin was considered to be about 8% but in the last year such institutions as the Mayo Clinic have revised their estimates. I've read both 15% and 20% as a recent guestimate but even the majority of those cases seem to need the environmental triggers of idiopathic PD.

There is also a school of thought in more than one research institution which feels that essentially all PD cases are genetic and that with rare exceptions, there is no idiopathic PD.

Conversely, PD appears in many ways to be a form of accelerated aging which. There are also schools of thought which are exploring the idea that PD is an inflammatory disease.

At any rate, maintain your caffeine intake from whatever source. If you smoke you might want to consider which is worse, lung cancer, heart disease or PD.

Read about the precursor symptoms. I don't mean the early symptoms which send you to the doctor for a diagnosis but the symptoms which appear to have no relationship to PD. Even a partial loss of sense of smell (you might notice that it affects your sense of taste because of the affiliation) depression, sleep issues, leg drag, change in handwriting, if you are a woman you might have prolonged pain in the neck or shoulders. None of these were ever seen to be related to PD but now they are considered symptoms which can begin years before the major loss of dopamine and norepinephrine neurons.

Of course, they could be just what they are, but with your family history, it is important for your doctors to be aware.

Consider that this is a good time to adjust your diet to a more Mediterranean style diet; to begin an exercise program the stresses not only strength (I'm a great believer in that because of the issues I have seen in some PD patients who don't) but range of motion, flexibility and balance. Yoga is a great form of exercise and so in aquatherapy. And dancing.

My husband has PD and I speak from both good and bad experience.

I agree with Lady Dawn..she knows of what she speaks.
I have had Parkinson's for going on 6 years now. When I first was diagnosed they thought I had CBGD, which is literally a "death sentence". When it was found that I had Parkinson's I was actually "relieved". (CBGD would have me "pushing up daisies" long ago.) After some research, done by my sister-in-law, I found out that my father had three brothers that had the disease. Now I know why my father had such a "disfunctioning" family...in those days there were no drugs to help slow the disease down. My brother called me on the phone last year and told me that he "also" has come down with Parkinson's. I've had the disease for 6 years. The drugs that are coming out now, thanks to research, slow the symptoms down measurably. As long as I keep up with my "treadmill" and "weight" workouts I'm doing pretty good. There are a lot of people that don't even suspect me having Parkinson's....so even thogh it "may" be inherited, it's not the end of the world. You just have to have a "don't quit" attitude, and a loving family that cares enough to try to understand what you're going through.

My identical twin brother has had Parkinson's for 14 years or so and has diskonesia; a side effect from the drugs he takes to manage his parkinsons. As we know identical twins start out from one egg and split into equal parts. Needless to say I don't have Parkinson's and can guarantee I will not get it. My twin brother is confined to his unit where he lives mostly and has cracked 9 ribs as well as his sturnam with the many falls caused by parkinsons, and its related drug side effects, over the recent past. In this light I would suggest that Parkinson's is not heredity but a condition of ones environment and how one deals with life on ones journey through the physical plane. I'm not a doctor but I do know Dr's have as many views as those who are not Dr's do. Relax, enjoy your life and be comfortable that if the parkinson's card appears in your life it would be more a part of your journey, thought processes and life experiences than anything you parent or parents may have experienced. PEACE!

As with many questions, the correct answer is, "It all depends..."

However, being unaware of any Parkinson history on either side of my family tree and after seeing how much and how many types of fungicide, pesticide, and herbicide had been stored in my parents' house and garage, I have to wonder if my father's food garden (tended almost 30 years) might have been a contributing source for both my parents' "Parkinsons."

By the way, after my mother began to refuse physical therapy, exercise, and walking, and then became sedentary, her symptoms went from "mild" to debilitating in a matter of a few months. Medication had no beneficial effect after that; the so-called "dopamine honeymoon" (almost 8 years on medication) apparently was over, too.

I'll leave it up to you to make any connections....

I'd also like to share this information about parkinson's disease, I wrote this article to make the people aware of the cause, symptoms and management of the disease especially in long term care facilities: http://www.infolongtermcare.org/long-term-health-care-seniors/diseases-in-elderly/what-is-parkinsons-disease/ . which may help one way or another.
