Noninvasive deep brain stimulation technique shows early promise for treating Parkinson's disease

A novel, noninvasive brain stimulation approach—known as transcranial temporal interference stimulation (TIs)—may offer a new way to treat motor symptoms in Parkinson's disease without the need for surgery, according to a pilot study appearing in eBioMedicine. The technique, which uses overlapping electrical currents to selectively target deep brain regions, significantly improved movement in patients compared with a sham treatment when targeting the subthalamic nucleus.
