Ambiguous paroxysmal events: Brief isolated jerk

A nonepileptic, entire body jerk typically occurs in transition to stage 1 non-REM sleep, (hypnicjerk). These jerks occur at all ages and can lead to evaluation of seizures, especially when they are unusually violent. In this video EEG, there are no significant EEG correlates associated with the jerk.
