[|Human|] hi, my name is mary. i have a younger brother who was hit in the head by a metal pipe when he was 5 years old. he got 46 stiches..6 on the outside and 40 on the inside.  when he became a teenager he started to become a different person.  he would get very angry and he would snap at us for no reason at all. and it is getting worse.he got married 2 years ago. he gets mad at his wife for stupid reasos and he starts texting her and calling her all kinds of na  mes then he starts texting my sister and my mom terrible things about his wife.  the hospital never took an mri or xrays..i keep wondering if he could have some kind of brain damage, he is 35 years old.
[|AI|]  Hi, I read your query in detail and can understand the concern you have for your brother. A brain injury can many a times lead to long term impact and depending on areas involved, it can lead to personality changes as well (even without any motor or sensory deficit). Loss of inhibition, irritability, change in personality are common changes following head injury. As a psychiatrist, I would advise a brain scan (MRI) to see if there are any residual lesions and which area was affected. Psychometric testing for cognitive functions could also be done. Depending on all that, a course of low dose anti-psychotics could be useful for your brother. Try fixing an appointment with a local psychiatrist for the needful. Best wishes.
