Transcranial Direct Current Stimulation in Psychiatric Disorders: A Comprehensive Review.

Transcranial direct current stimulation (tDCS) is a noninvasive brain stimulation technique that has been gaining favor as a viable tool in Psychiatry. The purpose of this review is to summarize the evidence of tDCS as a treatment of disorders such as depression, schizophrenia, and obsessive-compulsive disorder (OCD). Current findings indicate that tDCS is probably effective in non-treatment-resistant depressive patients. Regarding schizophrenia and OCD, present evidence is not robust enough, although preliminary results indicate that tDCS is a promising technique. Therefore, more trials are needed before using tDCS in a clinical setting.
