Parkinson's disease patients show unprecedented improvement in motor function through new deep brain stimulation technique, clinical trial reveals
BOSTON — A landmark clinical trial published today in the New England Journal of Medicine has unveiled a novel deep brain stimulation technique that significantly improved motor function in patients with Parkinson's disease. Conducted by researchers at Massachusetts General Hospital, the adaptive DBS system, which adjusts stimulation in real time based on brain signals, led to a 45 percent reduction in tremors and rigidity among 60 trial participants over a 12-month period. The findings, announced Wednesday, represent the first successful use of closed-loop technology to target Parkinson's disease symptoms, which affect approximately 10 million people worldwide. The technique involves implanting electrodes that continuously monitor and modulate neural activity, potentially reducing the need for medication. Researchers call for larger, longer-term studies to assess durability, but experts say this breakthrough could transform care for the progressive neurological disorder.
