A treatment that involves inserting electrodes into the brain can improve Parkinson’s symptoms even at early stages of the disease, research has shown.
Currently, Deep Brain Stimulation (DBS) is reserved for patients with advanced Parkinson’s disease who can no longer be treated with medication alone.
The Earlystim study showed that DBS produced a 53% improvement in motor skills over a period of two years. In comparison, no change was seen in patients receiving the best drug treatment.
Patients given DBS also saw a 30% improvement in various activities of daily life, including speech, writing, dressing and walking.
Side effects from drug treatment, including uncontrollable movements, were reduced by 61%.
