I am not sure what symptoms you are trying to treat. Are the delusions still happening ? Are the head aches responsive to Tylenol or Ibuprofen ? Have you tried using foam ear plugs for noisy environments ?

Respiridone is a powerful drug. No psychoactive drugs is to be taken lightly. Different psychiatrists have different specialty skills. Maybe there is a psychiatrist who has more experience with head injuries. I was on Olanzapine for a few months. It did a good job of settling my mind down.

Have the doctors done any blood work ? B-12, folate, D-3, magnesium and other levels should be checked. Even hormones should be checked.
