He is Type 1 Diabetic and Epileptic. I am curious if rather than schizophrenia, he could be reacting to his epilepsy medication.he used cocaine and alcohol for about a month just before being admitted as a mental patient. I worry about him being on even MORE medications. He will probably have to receive treatment at the County Health Department since he doesn't have money or insurance. However, cocaine use certainly could, if a careful, lifelong history were not taken.
Alcohol use can also complicate diagnosis.
It might be wise to have your friend obtain a second diagnostic opinion. I am an researching this disorder for my independent study project. Information seems to be scarce, so I would greatly appreciate any assistance you could offer. I've been taking 5 mg of Paxil for 18 months. Some agents similar to Paxil may cause reduced thyroid function over time.
