Hello and welcome to Healthcare Magic. Thanks for your query.
Sudden outbursts of anger and violence can be due to psychiatric problems, personality problems, or sometimes, due to a form of epilepsy
. Your brother needs a detaied evaluation and psychological assessment to ascertain the cause of his problems.
Further treatment will depend on the likely cause. If it is due to a psychiatric problem or a behavioural problem, then there are effective treatment options in the form of medication and counselling
which can help. So, please take him to a psychiatrist
for a detailed evaluation and further treatment.
Wish you all the best.
Dr. Jonas Sundarakumar
