Electrical Stimulation of Brain via Scalp May Ease Bradykinesia

Electrical stimulation given through the scalp to a brain region called the supplementary motor area may ease certain aspects of upper limb bradykinesia in people with Parkinson’s disease, a small study suggests. The study, “Transcranial direct current stimulation of supplementary motor area improves upper limb kinematics in Parkinson’s disease,” was published in Clinical Neurophysiology. Bradykinesia, a hallmark Parkinson’s symptom, is characterized by slow movements, delayed reaction times, and decreased amplitude of movements (that is, smaller movements).…
