Hi I can't agree more about exercise. My husband is awaiting Datscan after having shoulder problems for last couple of years. One of his most problematic symptoms is depression and I aren't sure if this is related to Parkinsons or the lengthy diagnostic process but playing golf and weight lifting makes him incredibly more positive and reduces the tremor that affects his hand arm and shoulder. On the days that he doesn't exercise he seems to be incredibly low so despite some apathy he does force himself to do exercise and always feels more positive afterwards.
