We experienced a fast onset of Vascular Dementia/Alzheimers/Parkinsons, one year ago. Medical advice was grim. We discovered that some medications caused condition to be worse. Once off the meds he stopped shaking and his mind was clearer. Throughout this monster roller coaster ride, first I tried to fix him... Then bounced from no hope to hope, denials to realization, etc. He says there is nothing wrong with him. I see deterioration in upper intellegence in many ways. He is happy, I am suffering each minute of the day. My heart is broken.
