What this trial studies

This study investigates the impact of transcranial alternating current stimulation (tACS) on anxiety symptoms and related somatic issues in patients diagnosed with anxiety disorders. Forty participants will undergo a structured evaluation and receive either active or sham tACS treatment over a week, with assessments conducted before and after the intervention. The study aims to explore the underlying neural mechanisms of anxiety through functional magnetic resonance imaging (fMRI) and various neuropsychological tests. The treatment protocol involves specific electrode placements and stimulation parameters to assess the efficacy of tACS.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 60 with a confirmed diagnosis of anxiety disorder and specific symptom severity.

Not a fit: Patients with severe somatic diseases, other neurological disorders, or those who cannot undergo MRI will not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could provide a novel non-invasive treatment option for patients suffering from anxiety disorders.

How similar studies have performed: Previous studies have shown promising results with tACS in treating various neurological and psychological conditions, suggesting potential for success in this approach.
