Summary

This study looked at whether a newer type of deep brain stimulation (DBS) electrode, which can steer electrical signals more precisely, improves mood and movement in people with Parkinson's disease. 105 participants received the directional electrodes as part of their standard care. Researchers measured changes in non-motor symptoms and motor function over 12 months after surgery.
