Thank you, pegleg, . . . indeed Parkinson's and Amyotrophic Lateral Sclerosis have many similar symptoms; both affect the motor nervous 'system' . . . but the 'dopamine' rather than 'glutamate' neurons are affected in Parkinson's. Advances in medical or biological science may help heal both disorders.

Thelma is one of my favorites, I only wish they would post more!

One of neurology's biggest problem is insufficient precision, . . . is the data sufficiently precise the conclusion validly follows therefrom? Such is the problem I think in the case of the question of whether females are at greater risk if they develop the disorder, even though they are believed to have a significantly lower risk incurring Amyotrophic Lateral Sclerosis.
