Had brain surgery, mean and aggressive, hallucinations of people abusing him. Treatment?
human
My father-in-law recently had brain surgery to remove a benign melingioma about the size of a lemon from right middle hemisphere of his brain. They have labeled the surgery a "success" and he is currently in inpatient rehab to help regain physical function, however he has become very mean and aggressive. He's even had hallucinations of people abusing him or is lying, we aren't sure which. Is this to be expected and if so is there any treatment available.

HelloI have gone through your query and understood your concerns. In my opinion he needs consultation with a neurologist as after the surgery he is the one who take care of the upcoming situation. The symptoms are quite normal in many people and there is treatment for this antipsychotics plays a good role and along with this  cognitive behavioral therapy will help him to get normal soon. Thank you.
