Theta burst stimulation to the right inferior frontal gyrus for autism

Official title: Explore the Impacts of Theta Burst Stimulation Over the Right Inferior Frontal Gyrus in Autism Spectrum Disorder: Combination of Clinical Symptoms, Neuropsychological Function and MRI

Run by Chang Gung Memorial Hospital · NCT07579494 · Data updated 2026-11-12

This study will try intermittent theta burst stimulation over the right inferior frontal gyrus to see if it improves core autism symptoms and thinking and daily living skills in people aged 8-30 with ASD.

Is this trial a fit for you?

Likely a good fit

Ideal participants are people aged 8-30 with ASD (DSM-5 level 1 or 2) who pass the UBACC capacity screen, are on stable treatments or have declined conventional options, and have no contraindicating medical conditions or metal implants.

Probably not a fit

People with severe epilepsy, major cardiovascular or systemic disease, significant brain injury, implanted pacemakers or medication pumps, those with DSM-5 level 3 ASD, or those outside the 8-30 age range are unlikely to be eligible or to benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Participants aged 8-30 with DSM-5 ASD level 1 or 2 confirmed by ADOS-2 will receive intermittent theta burst stimulation (iTBS) targeted to the right inferior frontal gyrus. Clinical symptom ratings, adaptive functioning measures, neuropsychological tests, and MRI-based neurophysiological signals will be collected before and after the iTBS course to detect changes. The protocol requires stable treatment regimens or documented treatment nonresponse/decline and capacity to consent (UBACC ≥15). Key exclusions include epilepsy, severe systemic or neurological disease, significant brain injury, and implanted metallic devices.

Why it matters

Potential benefit: If successful, the treatment could reduce core autism symptoms and improve cognitive and adaptive functioning without adding medications.

How similar studies have gone: Preliminary TMS/TBS studies in autism and related disorders have shown mixed but occasionally promising results in small samples, so the approach remains experimental.
