<bot>: Hello thanks for choosing Chat Doctor for your health related queriesYour son developed concussion in 2008, and he developed Bipolar disorder and mania after that. He was no Olanzapine and Carbamazapine for that. Now on lowering the doses he is experiencing hallucinations. Serious head injury commonly get complicated in psychotic symptoms. He is having these symptoms because of complication of head injury and reduction of antipsychotic Zyprexa or Olanzapine resulted in relapse of symptoms. I would advise you to consult his psychiatrist again and get him evaluated for evidence of psychotic symptoms. Thanks, hope this helps you
