Abstract
Transcranial direct current stimulation (TDCS) has been established as a noninvasive tool for modulation of
cortical function. It involves the passing of a weak direct electrical current through the cerebral cortex using
electrodes placed upon the scalp. TDCS decreases cortical excitability with cathodal or increases excitability with
anodal currents. There are few past reports of TDCS to treat psychiatric disorders. However, stimulation with
different parameters in different groups of patients needs additional studies. The aim of this review is to discuss
the potential mechanisms of action and use of TDCS.
Key words: transcranial direct current stimulation, neuromodulation, effect, treatment
