My Husband Is 58. For Several Years He Has Had

My husband is 58. For several years he has had a tremor in his hands and fingers. He works as a fishing guide in the summers. His father had was diagnosed with Parkinson's at age 62. For the past year, my husband has been sweating profusely at night. This got a lot worse when we bought a TemperPedic type bed. He drenches himself and the sheets. The sweating and body odor have begun to alarm me. He has to bathe before and after bed! The odor in the middle of the night smells like someone who hasn't bathed for a few weeks! Is there any connection between Parkinson's and body odor? He also has been having trouble getting over colds the last 2 years - they linger on with cough, chills, and extreme fatigue for weeks. This is a man who has always had high stamina and strength.
