Transcranial direct current stimulation (tDCS): A new tool for the treatment of tinnitus?

Abstract

Keypoints: 1. Transcranial direct current stimulation (tDCS) is a non-invasive technique of cortical stimulation encompassing a relatively weak constant current flow (between 0, 5 and 2 mA) through the cerebral cortex via scalp electrodes. 2. Several studies already revealed that tDCS can influence working memory, decision making, risk-taking behavior, impulsiveness, and emotions responsive to visual material in healthy humans. 3. Major depression and tinnitus have also shown promise in few pilot studies. 4. This chapter will review tDCS and its potential as treatment for tinnitus. © Springer Science+Business Media, LLC 2011.
