My 16 year old niece had a seizure 2 weeks ago. Witness advised that she has fainted and that her arms an legs were jerking. this apparently did not las t long. She was immediately hospitalised, EEG, CT & MRI scans were done. EEG was good, and MRI showed a shadow on the brain. She does not have a history of any illness, no symptoms, never had a headache. For a month she was on Roaccutane tablets for severe case of pimples. Could you please advise what could be the problem
