- Although bilateral subthalamic deep brain stimulation (STN DBS) provides greater relief From the symptoms of Parkinson`s disease (PD) than unilateral STN DBS, it has been suggested that unilateral STN DBS may be a reasonable treatment option in selected patients, especially those with highly asymmetric PD. In previous studies on the effect of unilateral STN DBS, the asymmetry of PD symptoms was not prominent and the mean follow-up durations were only 3 to 12 months. In this Study, we report Our findings in a series of 8 patients with highly asymmetric PD who were treated with unilateral STN DBS and were followed for 24 months. Serial changes in Unified Parkinson`s Disease Rating Scale (UPDRS) motor score and subscores in the ipsilateral, contra-lateral, and axial body parts were analyzed. Unilateral STN DBS improved the UPDRS motor score and the contralateral subscores in the on-medication state for 5 nonfluctuating patients and in the off-medication state for 3 fluctuating patients. However, the ipsilateral subscore progressively worsened and reversed asymmetry became difficult to manage, which led to compromised medication and stimulator adjustment. At 24 months, all the patients were considering the second-side Surgery. Out, results Suggest that bilateral STN DBS should be considered even in highly asymmetric PD.
