Periictal water drinking revisited: Occurrence and lateralizing value in surgically confirmed patients with focal epilepsy.

ABSTRACT:

Objective

Periictal water drinking (PIWD), which is a rare seizure-related autonomic behavior, has been reported in temporal lobe epilepsy (TLE) but only rarely in extra-TLE. Additionally, the lateralizing value of PIWD is controversial. We aimed to clarify the occurrence and lateralizing value of PIWD in patients with focal epilepsy.

Methods

This retrospective study included 240 focal epilepsy patients aged >10 years with a favorable postoperative seizure outcome (Engel class I). PIWD was defined as water drinking behavior during a seizure or within 2 min in the postictal phase. The occurrence of PIWD documented on video-electroencephalogram monitoring was assessed. The lateralizing value of PIWD was analyzed among patients whose language dominant hemisphere was identified.
