What this trial studies

This clinical trial investigates the impact of multiple sessions of transcranial direct current stimulation (tDCS) on behavioral, physiological, and electrophysiological measures in high-functioning adults with Autism Spectrum Disorder (ASD). Participants will undergo a crossover design where they receive both active and sham tDCS while engaging in social learning tasks. The study aims to determine whether active tDCS can enhance performance on these tasks compared to sham stimulation, with assessments conducted before and after each intervention block. The ultimate goal is to develop effective treatments to improve social communication impairments associated with ASD.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-35 who are proficient in English and diagnosed with autism or high traits of autism.

Not a fit: Patients with a history of neurological disorders, major medical needs, or those currently pregnant may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved social communication skills and overall quality of life for individuals with autism.

How similar studies have performed: Other studies using tDCS for cognitive and behavioral improvements have shown promising results, suggesting potential for success in this approach.
