Detailed Description
This study is a randomized, sham controlled study to evaluate the efficacy of cTBS as a treatment for executive function deficits in individuals with autism spectrum disorder between 6 and 16 years of age. The study duration is approximately 1 months, with the cTBS sessions lasting for 4 weeks, 5 times a week, for about 20min each. Several scales will be used to assess for symptom severity and adaptive functioning. The executive function will be evaluated by Behaviour Rating Inventory of Executive Functioning (BRIEF) questionnaire. Cognition will be assessed using functional near - infrared spectroscopy (fNIRS).
This study also involves a type of brain imaging known as magnetic resonance imaging (MRI) at the beginning and at the end of the 4 weeks daily cTBS to better understand the effects of cTBS on brain structure and function. Investigators will measure the size and connections of different parts of the brain to assess brain structure and blood flow.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Active treatment
Active cTBS treatment will be delivered at an intensity that is 70% of the resting motor threshold (RMT).
cTBS consist of bursts of 3 magnetic pulses at 30 Hz repeating every 200 ms for 300 pulses.
cTBS repeat twice with 15 min interval.
Treatment will be applied in central suleus.

The cTBS sessions last for 4 weeks, 5 times a week.

Sham Comparator: Sham treatment
Sham rTMS will be delivered using the same stimulation parameters and at the site of active treatment, but with only the side-edge resting on the scalp.
The coil will be angled 45 degrees way from the skull in a single-wing tilt position.
This method produces sound and some somatic sensation (e.g.
contraction of scalp muscles) similar to those of active stimulation, but with minimal direct brain effects.
