The patient is a 62-year-old male diagnosed with Parkinson’s disease 10 years ago, presenting with severe motor fluctuations, tremors, and dyskinesia poorly controlled by medication. After thorough evaluation, he was selected for deep brain stimulation (DBS) surgery targeting the subthalamic nucleus. The procedure was performed under general anesthesia, and electrodes were implanted bilaterally. Postoperatively, the patient showed marked improvement in tremors and rigidity, with reduced medication requirements. Rehabilitation and follow-up continued for 6 months with sustained benefits and no surgical complications.
