Therapeutic Improvement in People With Schizophrenia Undergoing tACS/CBTp (Transcranial Alternating Current Stimulation Applied Pre-cognitive Behavioral Therapy for Psychosis) Associated to Usual Medication Regimen

For the transcranial stimulation we will use the tES device from NeuroMyst,. The gamma pulses are delivered to a study participant via stimulating electrodes positioned at participant's head according to the required technique. The tACS will be applied the first 20 minutes from the classic CBTp session for the experimental group.

For the Sham group the investigators will use the same tES device from NeuroMyst. The Sham stimulation will be applied only for a few seconds in Sham group. The CBTp will follow the same protocol for both arms.
