In newly diagnosed seizure patients though the norm is to do an electroencephalogram (EEG), underlying structural abnormalities will be better depicted on magnetic resonance imaging (MRI), and EEG may turn out to be normal. Since a wide variety of structural abnormalities in the brain can lead to seizures, studies had shown that MRI was more effective in detecting lesions accurately in addition to an EEG, so it is better to include MRI as a first line of investigation in seizure patients for early detection, treatment, and better prognosis of underlying structural abnormality.
