Eyelid apraxia associated with deep brain stimulation of the periaqueductal gray area

J Clin Neurosci. 2014 Sep;21(9):1652-3. doi: 10.1016/j.jocn.2014.03.002. Epub 2014 Apr 13.


We report a patient with eyelid apraxia following deep brain stimulation of the periaqueductal gray area. Based on the position of our electrode, we argue that the phenomenon is linked to inhibition of the nearby central caudal nucleus of the oculomotor nucleus by high frequency stimulation.

Keywords: Deep brain stimulation; Eyelid apraxia; Periaqueductal gray area.
