Effect of tDCS on Inflammatory Biomarkers in Chronic Schizophrenia (tDCS)

April 24, 2024 updated by: Dr. Debadatta Mohapatra, All India Institute of Medical Sciences, Bhubaneswar

Effect of Transcranial Direct Current Stimulation (tDCS) on Inflammatory Biomarkers in Chronic Schizophrenia: A Randomised Double-Blind Controlled Trial.

The study is a randomized, double-blind, parallel-arm, sham-controlled trial that aims to compare the effects of transcranial direct current stimulation (tDCS) versus sham stimulation on inflammatory markers (IL-6 and TNF-alpha) and clinical outcomes (PANSS, AHRS, CGI-SCH, GAF) in patients with chronic schizophrenia over 10 days of treatment. The primary objective is to assess changes in IL-6 levels, while secondary objectives include evaluating changes in TNF-alpha, symptom scales, and adverse events. The study will be conducted at the psychiatry department of AIIMS Bhubaneswar, with 60 patients aged 18-60 years with moderate-to-severe schizophrenia symptoms randomized to receive either active tDCS (cathode over left temporo-parietal junction, anode over left dorsolateral prefrontal cortex) or sham stimulation. The researchers hope to elucidate the potential immunomodulatory effects of tDCS and its impact on symptoms in chronic schizophrenia, which may lead to more targeted, multifaceted interventions to improve patient outcomes.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Treatment group
the cathode will be located over a point midway between T3 and P3 (left temporo-parietal junction, assumed to correspond to a region including BA 22, 39, 40, 41, and 42, depending on the patient) and the anode will be placed with the middle of the electrode over a point midway between F3 and FP1 (left prefrontal cortex: dorsolateral prefrontal cortex, assumed to correspond to a region including Brodmann's areas [BA] 8, 9, 10, and 46, depending on the patient).The transcranial brain stimulation will be given 2 sessions per day for 10 days, in which 20 minutes of stimulation with an inter-session interval of 3 hours.
tDCS is a non-invasive neuromodulation technique that has gained attention for its potential to influence neural activity and address cognitive and functional deficits in individuals with schizophrenia. It involves applying a weak direct electrical current to the scalp, which can increase or decrease the excitability of underlying brain regions.
Sham Comparator: Sham control group
To Maximize the stimulatory effects 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.
