A New Study Identifies a Potential Cause of Parkinson’s

Researchers have identified a key brain network that could reshape how doctors understand Parkinson’s disease and drive development of more precise treatments.

Parkinson’s has long been viewed primarily as a movement disorder, marked by tremors, muscle stiffness and difficulty walking. But the disease can also affect sleep, blood pressure, digestion and cognitive function. Symptoms often worsen under stress and, in some cases, improve with music, suggesting that Parkinson’s involves more than just motor control.

To better understand what drives those varied symptoms, scientists turned their attention to a brain network only discovered in 2023: the somato-cognitive action network, or SCAN. In a new study published in Nature, researchers found that this network may play a central role in Parkinson’s—and that targeting it with brain stimulation could help relieve symptoms.
