He was forgetting things that happened recently, but talking constantly about the old days, was confused, having close calls while driving, acting out sexually, etc. following me everyplace. Dr. put him on Aricept and later Zoloft. Now I am questioning myself. Am I losing it?
I suggest that you start by Googling the Lewy Body Dimentia Association. also, if your dad hasn't already signed a HIPPA form allowing his doctors and other medical professionals to speak directly to you and other family members, be sure to do so ASAP. You can get template forms off the internet.
Good luck with the journey ahead.
