My father fell down the stairs 3 month ago and he diagnosed brain traume. He prescirbed with drugs for trauma absorption and phenitoin and halopridol. After 2 month, because he was taking varfarin (his legs swelled) he diagnosed hematoma (subdural I think) then he had hematoma surgery. Now is his verny unconcious. He can't remember a second ago. It's like Alzimer. He understands that he can't remember things and it makes him more anxious. I don't know if these symptoms will go away or will remain.... Please help
