Abstract: | Deep Brain Stimulation (DBS) of the subthalamic nucleus (STN) is a well-recognized intervention for Parkinson’s Disease (PD). We used LEAD-DBS, a toolbox facilitating DBS electrode reconstructions and computer simulations based on postoperative MRI and CT imaging, to investigate the interaction and followed benefits of electrical field generated by STN-DBS and surrounding areas, such as caudal Zona Incerta (cZI). Thirty-two PD patients, treated with directional STN-DBS in the period 2016–2018 at the Walton Center NHS Foundation Trust, were retrospectively recruited. Their MRI and CT imaging were analyzed with LEAD-DBS to measure the volume of tissue activated (VTA). Considering the clinical outcome based on the UPDRS III score improvement of 62.65% at 6 months follow up, we found a VTA intersection of 21.5% with motor STN and 61.7% with cZI. These observations may support the contribution of cZI deep stimulation to improve clinical outcome of PD patients treated with DBS, promoting the intriguing path of dual targeting. |
