Hello, My girlfriend's husband is in his early 60's. He had a quadruple bypass about 6 years ago. About 3 1/2 weeks ago he started acting out of character. He started going to church and praying daily, this isn't a bad thing but there are other strange things. He counts things, he stopped watching TV totally and he had been an avid watcher. Upon returning home from an errand he called the police and told them he was afraid to enter his house. A week before this all started he had a cat scan of his head for headaches. The doctor said it was ok but the bloodwork showed a very low sodium count. He gets $$$ out of his checking and immediately looses it. His total personality has changed within 3 weeks. His wife took him to the ER on Saturday and they did an Alzhiemer test which he passed and they think she is making all this up and sent him home. He won't change PCPs because the hospital ER said he is fine. Has anyone ever had anything similar happen before? Please give me clues to look up for answers. Thanks for any help. He is also gluten allergic and has been on gluten free diet for years, plus has fibromyaga.
