We report on a 70-year-old female patient with Parkinson's disease, who showed an
improvement of a preexisting apraxia of lid opening on electrical impulses, so-called
deep brain stimulation (DBS) delivered to the subthalamic nucleus (STN). This was
not described by any other authors before. Up to now, the appearance of apraxia of
lid opening was observed only as a side effect after deep brain stimulation in the
nucleus subthalamicus. We suggest that these differences may be due to the region
of the nucleus subthalamicus that is influenced by the stimulation.
