C13: Parkinson's Disease

When I undertook my studies of sleeping practices, I also questioned those who were inquiring about Parkinson's Disease(PD), MS, and ALS (amyotrophic lateral sclerosis) (Lou Gehrig's Disease). I really didn't expect that there would be a connection to rebreathing, but I did investigate anyway. Since their cause is still unknown, I thought that perhaps I could find something valuable, some relationship. After a short while I discovered that there didn't appear to be any connection between sleeping under the covers and PD and ALS; therefore I discontinued the study of these outcomes.

However, I do have some thoughts.

ALS is considered in more than 90% of cases appears to be an autoimmune disease, as is MS. The key characteristic of ALS is the death of upper and lower motor neurons found in the motor cortex of the brain, the brain stem, and the spinal cord.

But I do have a theory about part of their symptoms, but not a cure.
Individuals with PD will walk with a shuffling, short step, gait. I believe that this can be avoided or improved in the early stages of the disease.
The auto immune reaction is causing both the attack on the nervous system, and an accompanying arthritis.
A process takes place. Due to the pain of arthritis individual begin taking shorter steps. When this takes place the brain, which is always learning, adjusts to the shorter steps, and starts making this shorter step normal, regardless of any pain.
However, as the arthritis increases, there will be an additions shortening of steps, and this too becomes internalized and normalized.
This process continues to the point, that regardless of the presence of any pain, the individuals gait is ratcheted down, to the point of being a shuffle.
Their gait or shuffle was the result of the brains ability to learn new movements.
Observers have noticed that those suffering PD, had not loss their ability to do other physical movements, such as riding a bike. My opinion here is that they didn't go through the same learning process that they went through with their walking. 
What does this mean: I would suggest that individuals who are beginning or show signs of PD, practice daily making long strides in their walking. They make a deliberate attempt to avoid restricting their stride.
Will this prevent PD. I don't believe so. But it should help reduce the results of the sidease.
