Abstract [en]

Deep brain stimulation (DBS) can be very effective in alleviating tremor, but adverse effects on speech are frequently reported, especially following bilateral DBS. Most of the existing literature on DBS and speech deals with the effects of DBS targeting the subthalamic nucleus or the ventral intermediate nucleus of the thalamus, which are the traditional targets for Parkinson’s disease and essential tremor, respectively. More recently, the posterior subthalamic area (PSA) has been highlighted as a particularly effective target for tremor; however, there are limited studies of PSA-DBS effects on speech.

We report speech outcomes for 14 persons with essential tremor during chronic PSA-DBS and at unilateral high-amplitude PSA-stimulation.

The objectives were to answer the following questions:

  • To what extent is speech function, and in particular articulation and voice, affected by chronic PSA-DBS?
  • How is speech affected by unilateral high-amplitude stimulation
  • Is bilateral chronic PSA-DBS worse for speech than unilateral PSA-stimulation?
