What this trial studies

This study is a randomized, double-blind, parallel-arm, sham-controlled trial that investigates the impact of transcranial direct current stimulation (tDCS) on inflammatory markers and clinical outcomes in patients with chronic schizophrenia. Over a 10-day treatment period, 60 patients aged 18-60 with moderate to severe symptoms will be randomized to receive either active tDCS or sham stimulation. The primary focus is to assess changes in IL-6 levels, while secondary objectives include evaluating TNF-alpha levels and various symptom scales. The research aims to explore the immunomodulatory effects of tDCS and its potential to improve symptoms in chronic schizophrenia.

Who should consider this trial

Good fit: Ideal candidates are right-handed patients aged 18-60 with a clinical diagnosis of schizophrenia for more than 2 years and moderate to severe symptoms.

Not a fit: Patients with psychiatric emergencies, co-morbid neurological diseases, or contraindications to tDCS may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to new treatment options that target inflammation and improve symptoms in patients with chronic schizophrenia.

How similar studies have performed: While the approach of using tDCS in schizophrenia is gaining interest, this specific application focusing on inflammatory biomarkers is relatively novel and has not been extensively tested.
