Scientists are testing an electric patch worn on the forehead that may help fight depression while the wearer sleeps. NeuroSigma’s external Trigeminal Nerve Stimulation consists of two electrodes that are strapped to the forehead and connected by wires to a cell phone-sized battery pack that can be worn around the waist.

The electrodes send small electrical impulses that stimulate the trigeminal nerve in the head, boosting blood flow in areas of the brain that affect seizures, mood and concentration. NeuroSigma has licensed the technology from UCLA, where device was originally designed treat seizures. In a clinical at UCLA, 11 patients saw a 50 percent reduction in their depression severity score after wearing the device eight hours a night for eights weeks. Scientists are now conducting a double-blind trial on 30 patients.
