Hello and welcome to Healthcare Magic. Thanks for your query.
The details you have provided are insufficient to make a definitive diagnosis. Your brother needs a detailed psychological assessment to find out what psychiatric disorder he is suffering from. Further treatment will have to be based on the diagnosis. So, I would advise you to discuss about his diagnosis and treatment plan with the psychiatrist
treating him, in order to get a clearer picture.
Wish you all the best.
