My father's doctor was a Parkinson expert at UF. He told us everyone over 80 has some form of Parkinsons.... My dad developed the Parkinsons gait after a stroke. Physical therapy was a huge help, but that gait worsened as he aged despite PT. I don't see Bidumb's arm movements and gait as Alzheimers, that is the effect of Parkinsons from all that I've read and heard...

I'm not a doctor, but I'm married to an excellent one and I stayed at a Holiday Inn Express in October....🙂
