Hello There. I can understand your concern for him. but its very difficult to say anything with just this much history. also along with a detailed history we need to conduct a proper clinical examination and also run some tests, if you have carried out any tests, you could also attach the reports so that it will be helpful for us to come to a clear idea. kindly consult a neurophysician in person for further evaluation and management, best regards, Dr. Anil kumar jain.
