Show Summary Details

Preview

In refractory patients who have extratemporal onsets, surgical treatment is often more complicated. These patients still have a higher chance of cure with surgery than with additional medication trials. In addition to routine video-EEG monitoring and MRI, further imaging studies such as PET or SPECT scans may help to localize onset. Intracranial electrode implantation followed by video-EEG monitoring is often required to definitively localize seizure onset and distinguish from eloquent cortex with brain mapping.
