Overnight video-EEG monitoring was performed, which captured 21 focal stereotyped motor seizures, characterized by sudden startled awakenings and irregular hypermotor activity in all four limbs (Figure 1).
Overnight video-EEG monitoring: one of the seizures arising from non-REM sleep (stage 2). K-complex is followed by fast rhythmic activity in the frontal regions lasting for 0,3-0,5 seconds, before EEG is obscured with myographic artifacts.
