Up to a third of people diagnosed with depression do not respond to antidepressants or therapy.

In such cases, patients may be prescribed neuromodulation therapy, which modulates brain activity in order to reduce depression symptoms. One promising form of neuromodulation therapy that researchers are investigating is transcranial direction current stimulation (tDCS).
