How a Tiny Electrical Current to the Brain is Treating Medical Symptoms.

The medical benefits of mild electrical stimulation of the cranium may seem like marketing hype, but decades of clinical research studies have verified that it does alleviate symptoms in a wide range of conditions. This method delivers very-low-frequency current to electrodes placed on the head, and that tiny current spreads across the brain to influence neurons and affect brain- network connectivity. Today, psychiatrists and neurologists commonly employ this technique as part of the therapy for people with anxiety, depression, posttraumatic stress disorder, epilepsy, Parkinson's disease, and a host of other conditions. Researchers are also reporting that stimulation can improvemental performance.
