Brain scans can now tell the difference between Parkinson's and other conditions

Researchers found that new ways of analyzing brain wave data can reliably tell the difference between Parkinson's disease and healthy brains. These new methods also show how medication changes brain activity in Parkinson's patients.

For years, diagnosing Parkinson's disease has relied on observing symptoms, which can be subjective and often means the disease is already advanced. This paper shows that specific patterns in brain activity, measured non-invasively, can act as clear markers. This could lead to earlier, more objective diagnoses and better ways to track how well treatments are working.
