This research redefines Parkinson’s Disease (PD) not merely as a motor disorder, but as a systemic pathology centered on the Somato-Cognitive Action Network (SCAN). By utilizing precision functional mapping and extensive datasets, the authors demonstrate that SCAN hyperconnectivity is a core feature of the disease, linking physical symptoms with cognitive and autonomic dysfunction. The study shows that effective treatments, such as levodopa and Deep Brain Stimulation (DBS), work by normalizing these specific neural circuits. Furthermore, the researchers utilized Transcranial Magnetic Stimulation (TMS) and focused ultrasound to prove that targeting SCAN-specific brain regions leads to superior clinical recovery compared to traditional methods. Ultimately, the authors propose reclassifying PD as a SCAN disorder to improve the accuracy of future diagnoses and the efficacy of personalized neuromodulation therapies.
