TRANSCRANIAL DIRECT CURRENT STIMULATION: A REVIEW -

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
