As I read the debates about exercise and about medications I am beginning to wonder if our opinions ( and rather strong ones) are related to which category of PD we have. I can well imagine someone whose main symptom is a tremor can live fairly comfortably without medication and may not even benefit from exercise more than anyone without PD. But those of us with gait and balance symptoms are more likely to depend on medication to be able to walk and maybe we need the exercise more too improve our gait. I am very grateful for my medication (side effects and all) and I'm very grateful for the observable benefits I get from exercise. I wonder how others feel about this.
