Transcranial Direct Current Stimulation and Cognitive Remediation Therapy for Psychosis

The proposed pilot study is a randomized controlled study to assess effectiveness of transcranial direct current stimulation (tDCS) to enhance cognitive remediation therapy in patients with psychotic disorders. tDCS. Patients will be randomized into two arms: active tDCS vs. sham tDCS. The active tDCS will be applied at a current of 1-2 mA (milliamperes) via two saline soaked electrode sponges (3 cm x 4.5 cm) applied to the side of the head. The investigators hypothesis is that the use of tDCS will enhance the improvement seen with cognitive remediation therapy.
