Deep Brain Stimulation May Put Parkinson’s Patients at Risk for Drowning. Swimming skills impaired after DBS

Swiss researchers identified nine Parkinson’s disease patients who lost their ability to swim after receiving deep brain stimulation (DBS) of the subthalamic nucleus.

All had been proficient swimmers even after they were diagnosed with Parkinson’s disease but discovered their swimming skills were impaired after DBS, reported Daniel Waldvogel, MD, of the University of Zurich, and co-authors, in a retrospective study. All the patients were able to walk and had motor symptoms that improved after DBS.
