My 82 year old Dad has had a dramatic change in his health the past 6 months. He is dragging his right foot and has pain on the outside (from his small toe to his ankle). He has weakness in his right hand, his handwriting is almost unreadable. He has personality changes, one minute he is himself and in a second he he saying mean things to me, my Mother (all new after 60 years of marriage), and although his short term and long term memory seem ok, he seems to be bringing up events from the past so he can talk bad about someone. Small town and he and my Mother have their family roots back to the early 1800 s so he knows everyone...and his personality change is evident to others. Questions like Is Charles doing ok? BP normal takes HCTZ but I notice 1 to 2 plus edema in the right foot. Mother claims to see a tremor in his right hand which I haven t seen, but it is posssible she is correct. HELP
