Hello thanks for asking from HCM for your health related queries I can understand your concern. His symptoms like anger outburst could occur due to some mood disorder like bipolar disorder or intermittent explosive disorder. Evaluation by a psychiatrist is needed to confirm diagnosis. He is also having difficulty in narrating a particular incident and this could be due to some anxiety like social anxiety. In intermittent explosive disorder medicines like mood stabilisers are commonly used. Medicines like Sodium Valproate, Lithium can be used to reduce his anger spells and he would feel better. Psychological treatment like anger management, relaxation exercises etc can help to reduce his symptoms. Visit a psychiatrist for prescription of drugs and for treatment options. Thanks, hope this helps you. take care
