Deep Brain Stimulation (DBS) has transformed the management of Parkinsons disease, enhancing patients quality of life. We retrospectively analyzed 10 patients who underwent Subthalamic Nucleus (STN) DBS at a Moroccan hospital. Pre- and postoperative assessments using the Parkinsons Disease Questionnaire revealed significant improvements in mobility, daily activities, and emotional well-being. Our findings underscore the importance of considering subjective well-being alongside clinical parameters in evaluating DBS efficacy for Parkinsons disease.
