Hello ! I read carefully your question and understand your concern. I would like to know what he is taking for his seizures. The brain farts and episodes of violence are common after a head concussion and may be a part of the so called Post traumatic stress disorder. His brain is suffering a dysfunction which involves also the memory and emotional regions of the brain. Some antiepilepsy drugs have a very good effect on these episodes too. Valproate and Carbamazepine are the best treatments for these episodes. I would recommend to switch on one of these therapies which are also helping for seizures and post concussion headache. Some other antiepilepsy drugs like Levetiracetam may aggravate this situation, it improves the seizures , but aggravates the violent behavior. So if he is beeing treated with Levetiracetam, I would strongly recommend to switch into one of the above mentioned drugs. I would also advise to make some changes in his diet, avoid alcohol and caffeine and take a lot of fruits and omega3 fatty acids. Hope to have been of help! Best wishes! Dr. Abaz Quka
