Got Head Injury. Started Behaving Abnormally. Could It Be Some Kind Of Brain Disorder?
Sorry to hear about your brother. This kind of behaviour does not come as a first symptom from brain damage. He would have suffered from seizure disorder in case of XXXXXXX damage in first place. It seems to be behavioural problem. He certainly needs to talk to a psychologist and a Psychiatrist to understand why his attitude towards people is so bad. You should not wait for this as his continued behaviour like this can pose hazard to his wife and if at all she gets pregnant then to their kid also. Psychiatric behavioural changes are mainly due to some chemical changes in the brain and secondary to organic damage to brain tissue.
Here it seems to be of primary cause. He would do good with medications from the psychiatry doctor if talking to Psychologist does not help. Sometimes talking to psychologist itself will bring out the inner him infront of himself and he would realize the issue himself. But do not hesitate if he's given medications for this as it is always better.
I hope this helps. Contact me for any further query. Thanks.
