title: Subthalamic nucleus deep brain stimulation in Parkinson disease patients over age 70 years.
abstract: The effects of subthalamic nucleus deep brain stimulation were studied in 52 consecutive patients (13 over age 70, 15 under age 60, 24 age 60 to 70). All groups had improvement of motor fluctuations and dyskinesia. Patients over age 70 had worsening of Unified Parkinson's Disease Rating Scale motor scores on medication, despite less medication reduction. Their activities of daily living and axial subscores worsened, particularly in those with preoperative gait difficulties.
