Intervention Effect of High Definition Transcranial Direct Current Stimulation (HD-tDCS) on Anxiety Disorder

tDCS is described as a non-invasive form of brain stimulation that uses a low-intensity, constant current applied directly to the head through scalp electrodes.

Sham HD-tDCS was delivered using the same protocol and current intensity, but the period of active stimulation was only during the ramp-up and ramp-down periods of 30 and 30 seconds.
