In this study, investigators will examine the treatment effects of transcutaneous electrical nerve stimulation with different stimulation frequencies on individuals with autism.
In this study, investigators will examine the treatment effect of transcutaneous electrical nerve stimulation at auricular area with vagus nerve distribution on high-functioning individuals with autism. Specifically, investigators will choose two ear acupoints: heart and shenmen. Participants will be randomized to either 1 Hz or 20 Hz tVNS group (up to 5 times per week) for three weeks.
Inclusion Criteria: 1. Autism diagnosed based on DSM-V classification criteria 2. 18-60 year old high functioning adult autism patients (e.g. Asperger's, IQ equal or greater than 80) 3. Subjects who do not show aggressive behaviors based on neuro/psychiatric evaluations as determined by a licensed study physician. Exclusion Criteria: 1. A history of chronic serious infection, any current infection, any type of cancer or autoimmune disease or other severe diseases; 2. Subjects taking any medications that confound the study results
High-functioning individuals with autism randomized to this group will receive 1 Hz tVNS stimulation for 30 minutes/day up to 5 times/week for 3 weeks.
