Transcranial direct current stimulation shows promise for depression therapy
Small amounts of electricity similar to the output of a common 9-volt battery could improve life for people living with major depression, the most common mood disorder. A new study at the University of Kansas will investigate the potential of transcranial direct current stimulation, or tDCS, whereby a safe, low current of electricity is applied to the brain by placing electrodes on a person's scalp. The painless technique may be a useful as a therapy for depression, especially in conjunction with antidepressant medications.
