A new study links a brain network called SCAN to Parkinson’s, showing abnormal connections that explain both motor and non-motor symptoms.
A new study in Nature identifies the somato-cognitive action network (SCAN) as a key brain network linked to Parkinson’s disease, showing abnormal hyperconnectivity between SCAN and dopamine-related brain areas in patients.
Analyzing data from 863 individuals, researchers found this pattern is unique to Parkinson’s, not seen in other neurological disorders.
The network connects movement control with attention, body awareness, and planning, helping explain both motor and non-motor symptoms.
Treatments like deep brain stimulation and transcranial magnetic stimulation that reduce SCAN hyperconnectivity were significantly more effective, suggesting targeted therapies could improve outcomes.
Experts say the findings reframe Parkinson’s as a network disorder, opening paths for precision, non-invasive treatments.
