Hi, he needs proper regular medications and counseling ..he can improve completely and can do thier routine activities but needs take medications . Consult Psychiatrist

I understand your concern towards your father. However more clarity is needed regarding his problem to decide on the severity of your present condition. It is easily manageable with appropriate treatment, so that dysfunction due to the same can be reduced and his quality of life will improve. Some counselling sessions along with medical help might be useful for him. I would also be more than happy to help you with that if you are looking for further online assistance or second opinion. You can directly consult with me through Practo as needed. Online chat consultation is available.
