Summary

This clinical trial aims to compare the efficacy and safety of transcranial Alternating current stimulation (tACS) vs. transcranial Direct current stimulation (tDCS) vs. sham stimulation in chronic schizophrenia.

The main question it aims to answer is:

• In comparison to tDCS, can tACS improve the clinical outcome of patients with chronic schizophrenia?

Participants will be randomised into 3 groups receiving either tDCS, tACS or sham stimulation and changes in psychopathology and neuro-cognition with the interventions will be compared within and between the groups. The primary outcome measure is the Positive and Negative Syndrome Scale (PANSS), while secondary outcome measures are the Auditory Hallucination Rating Scale (AHRS), Brief Cognitive Assessment Tool for Schizophrenia (B-CATS), and Global Assessment of Functioning (GAF).

Conditions

Interventions

DEVICE

transcranial Alternating current stimulation (tACS)

It is a non-invasive brain stimulation technique that uses small, pulsed alternating current (1mA) to modulate lasting cortical excitability, producing facilitatory or inhibitory effects upon a variety of behaviours, with proven efficacy in various neuropsychiatric disorders.

DEVICE

transcranial Direct current stimulation (tDCS)

It is a non-invasive brain stimulation technique that uses constant, low direct current to modulate lasting cortical excitability, producing facilitatory or inhibitory effects upon a variety of behaviours, with proven efficacy in various neuropsychiatric disorders.

DEVICE

Sham controlled

1mA current will be applied for the first 30 seconds to provide the initial sensation of real stimulation, and then the current will be stopped, thus minimizing the stimulatory effects. It is known to have no effect on psychopathology/neuro-cognition and means to mimic the tDCS/tACS (in order to help blinding of the participants).
