My Dad had Lewy's Body Dementia. A horrible combo of Alzhiemers and Parkinson's. He has had a physical therapist coming to help him get stronger. When the pt is here is aware and can do everything the pt asks him to do. As soon as he leaves and all the rest of the day he is confused and can't do anything for himself. Is this normal? We can't seem to convince the pt that his behavior when he is here is abnormal to his daily routine. We need help it is making us all frustrated and confused.
