Apraxia of eyelid opening after subthalamic deep brain stimulation may be caused by reduction of levodopa

Atsushi Umemura et al. Parkinsonism Relat Disord. 2008 Dec.

Abstract

Apraxia of eyelid opening (ALO) is an infrequent side effect of deep brain stimulation (DBS) of the subthalamic nucleus (STN) for Parkinson's disease (PD). However, the pathogenesis of ALO after STN DBS is not well understood. We report on two patients who suffered from disabling ALO after bilateral STN DBS. Their ALO improved by resuming the levodopa medication that had been discontinued after the surgery. Although ALO after STN DBS is considered as an adverse effect of STN stimulation, postoperative modification of dopaminergic medication may be a cause of ALO after STN DBS.
