Currently he is anxtios , screaming and some times confused with his suroundings. He was on 40 mg Betanoid for 6 weeks , after brain surgery that left him paralized. Meningioma tumors were removed .
Hello! Welcome on Chat Doctor ! Your husband symptoms seem to be related to acute psychosis. Partial seizures, may trigger this situation. I don't think that these symptoms are related to Retinoid with Chat Doctor.  Considering the fact that he had brain surgery for a tumor, I would recommend consulting with a neurologist for a brain CT scan and some tests
