Ictal local field potential recordings in nucleus subthalamicus (STN) in a patient with idiopathic generalized epilepsy (IGE)

Rationale: For more than a decade STN has been discussed as a potential target for deep brain stimulation (DBS) and ictal recordings have been obtained in focal epilepsies (e.g. Loddenkemper et al., Journal of Clinical Neurophysiology, 2001). Recently, DBS of STN showed a beneficial effect in progressive myoclonus epilepsy, an epilepsy syndrome with a distinct seizure type: generalized myoclonic seizures (Vesper et al. Epilepsia 2007). Ictal field recordings from the STN were recorded simultaneously with surface electrodes in a patient with pharmacoresistant IGE. Methods: We report the case history of a STN-DBS…
