Neuropsychiatric Factors Contribute to Heterogeneous Motor Outcomes in Parkinson's Disease after Subthalamic Deep Brain Stimulation.

Summary: Deep brain stimulation is a great surgery for Parkinson's disease, but it doesn't work the same for everyone. Doctors wanted to know why some people get better results than others. They looked at 92 patients and found that mental health plays a big role. People with less anxiety and depression before surgery had much better movement after one year! Using this information, computers can now predict with 82% accuracy who will do best. This helps doctors make better, personalized treatment plans for each patient.
