Hi, a friend is severely affected by Parkinson's. He has been crying so much lately. I spoke to the staff at the nursing home about reviewing his meds. Seems like the only result is his doctor putting him on Cymbalta. He takes Lyrica. And I bet he is magnesium deficient. He has cramps. I would cry too of course if I had to endure what he is going through, but I am not convinced that the meds and nutritional deficiencies are not playing a part. Your thoughts please.
