Effect of tDCS on Inflammatory Biomarkers in Chronic Schizophrenia
Effect of Transcranial Direct Current Stimulation (tDCS) on Inflammatory Biomarkers in Chronic Schizophrenia: A Randomised Double-Blind Controlled Trial.
All India Institute of Medical Sciences, Bhubaneswar
60 participants

INTERVENTIONAL
Conditions
Summary
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.
Eligibility
Inclusion Criteria2
- \- 1. Patients clinically diagnosed with schizophrenia (F20 according to ICD-11) for a period more than 2 years receiving antipsychotics.
- \. Moderate to severe symptoms (PANSS score \>75 and/or CGI-SGH score \>4) 3. Patients of both sex 18-60 years 4. Right-handed. 5. Legally authorized representative (LAR) giving voluntary written consent for participation in the study.
Exclusion Criteria2
- \. Patients with chance of pregnancy. 2. Any psychiatric emergency (e.g. suicidal risk, catatonia, prolonged nutritional deprivation) or others (e.g.: aggression or excitement) 3. Co-morbid neurological disease: i) History of migraine. ii) History of seizure/epilepsy. iii) History of head trauma or organic disease.
- \. Any contraindication to tDCS procedure: i) Injury or local lesion in the scalp/head ii) Metallic implants in the head iii) Implanted brain medical devices 5. Left-handed.
Interventions
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.
