Abstract
Transcranial direct current stimulation (tDCS) is a neuromodulatory technique that has undergone intensive research over the past decade with promising results. tDCS is based on the application of weak, direct current over the scalp, leading to cortical hypo- or hyperpolarization according to the specified parameters. Recent studies have shown that tDCS is able to induce potent changes in cortical excitability as well as to elicit long-lasting modifications in brain activity. Over the last decade, tDCS physiological mechanisms of action have been intensively investigated. This research has given support for the investigation of tDCS applications in a wide range of clinical populations, including patients with post-stroke motor and language deficits, chronic pain, and tinnitus. Recently, its efficacy to treat psychiatric conditions has been explored increasingly. In this review, we will gather clinical studies involving tDCS to ameliorate psychiatric symptoms and discuss reasonable next steps in this direction.
