Perceptual and Cognitive Effects of Focal Transcranial Direct Current Stimulation of Auditory Cortex in Tinnitus.

ABSTRACT:

Objectives

Transcranial direct current stimulation (tDCS) has been studied as a potential treatment for many brain conditions. Although tDCS is well tolerated, continued study of perceptual and cognitive side effects is warranted, given the complexity of functional brain organization. This study tests the feasibility of brief tablet-based tasks to assess auditory and cognitive side effects in a recently reported pilot study of auditory-cortex tDCS in chronic tinnitus and attempts to confirm that this untested multisession tDCS protocol does not worsen hearing.

Materials and methods

Participants with chronic tinnitus completed two hearing tasks (pure-tone thresholds, Words In Noise [WIN]) and two cognitive tasks (Flanker, Dimension Change Card Sort) from the NIH Toolbox (2024
