Brief Summary
Although many children diagnosed with autism spectrum disorder (ASD) make significant progress in learning and their cognitive skills improve with applied behavior analysis (ABA), there are a significant number of children who show an absence or a plateau in various skills. Deficits in executive functioning are likely to be involved in many of these cognitive and learning disabilities due to poor functioning of the prefrontal cortex. Currently, the use of biological methods for improving learning and cognition is largely unexplored in research and practice. The aim of this study is to use of transcranial direct current stimulation (tDCS) in combination with ABA to improve the acquisition of educational programs for students with ASD. tDCS is a low-level electrical neurostimulation and is most effective when used in combination with an active training or teaching, facilitating the neuronal circuits used for that task. tDCS has been used for various indications over a couple of decades and has been shown to be very safe and has been well-tolerated by children with ASD. The mechanism of tDCS is not clear, however animal studies show that tDCS can stimulate the flow of calcium ions through channels in the astrocytes, activating them, and facilitating their role in synapse formation and therefore learning.

Outcome Measures
Primary Outcomes (2)
Change in the Behavior Rating Inventory of Executive Function (BRIEF)
The BRIEF is a parent-reported executive function questionnaire which utilizes T-scores, which has a mean of 50 with a standard deviation of 10, with a range of 10-100
Change measured once per month (at the end of each phase) for 5 months
Change in Electrodncephalogram (EEG)
Power, sample entropy, Lyapunov exponent, detrended fluctuation analysis, correlation dimension, and recurrence quantitative analysis (RQA) values on all frequency bands (delta, theta, alpha, beta, gamma, and gamma+) will be computed from 2-minute resting EEGs using a portable headset
Change measured once per month (at the end of each phase) for 5 months
Secondary Outcomes (2)
Change in the Pervasive Developmental Disorder Behavior Inventory (PDDBI)
Change measured once per month (at the end of each phase) for 5 months
Change in discrete trial training (DTT) data from applied behavior analysis (ABA) therapy
Obtained once at the completion of the study (5 months after the start of the study)
Other Outcomes (2)
Vineland Adaptive Behavior Scales (for demographic purposes)
Once during 4-week baseline for the entire study
Leiter-3 nonverbal intelligence assessment (for demographic purposes)
Once during 4-week baseline (if a similar test was not done in the past three years) for the entire study
Study Arms (2)
Active tDCS
EXPERIMENTAL\[Active stimulation first, then crossover to Sham stimulation\] Each participant will receive BOTH sham or active tDCS but the order of each will be randomized. The active tDCS and sham are procedurally identical. Participants in both arms will have the initial tingling sensation and the active tDCS stimulation will CONTINUE for 20 minutes at 1 mA (milliamps). All tDCS sessions will occur during ABA therapy.
Sham tDCS
SHAM COMPARATOR\[Sham stimulation first, then crossover to Active stimulation\] Each participant will receive BOTH sham or active tDCS but the order of each will be randomized. The active tDCS and sham are procedurally identical. Participants in both arms will have the initial tingling sensation, except in sham stimulation, the current will be DISCONTINUED after 30 seconds while the power indicator remains on for the remainder of 20 minutes at 0 mA (milliamps). All tDCS sessions will occur during ABA therapy.
Interventions
The anodal electrode will be placed over F3 using the international 10-20 EEG electrode placement system to target the left dorsolateral prefrontal cortex (DLPFC). The cathode electrode will be placed on the right dorsolateral prefrontal cortex. 40 stimulation sessions will be completed (20 active, 20 sham), each lasting 20 minutes per session at 1.0mA.
Eligibility Criteria
You may qualify if:
- Males and females between 5 and 12 years with autism
- Enrolled in an ABA program (school or in-home) supervised by a Board Certified Behavior Analyst (BCBA)
- Stable medical and behavioral treatments for at least 4 weeks prior to, and during the study
- Able to tolerate wearing tDCS as determined during a week-long daily desensitization training.
You may not qualify if:
- Any implanted metal device (heart pacemaker, cochlear implant, surgical clips, etc.)
- Severe neurological disorders such as TBI, brain tumor, intracranial infection
- Seizure disorder with a seizure within the last two years
- Skull defect
- Peripheral blindness or deafness
- Medication that might affect tDCS: There have been a few studies concerning the effect of various medications on tDCS. Some may block and others may enhance the effects depending on many factors. The assay used to test these medications was its effect on the motor cortex after stimulation and this may not apply to our montages, however, in order to minimize the chances of having medication affect our results, participants taking the following medications will be excluded:
- Na or Ca channel blockers which will include all anti-seizure medications
- Medications that affect the NMDA receptors including dextromethorphan, cycloserine
- Serotonin reuptake inhibitors
- Dopamine stimulating or blocking medications including pergolide, bromocriptine and all antipsychotic medications
- Norepinephrine stimulating or blocking agents including propranolol and the stimulants
- Drugs that can lower seizure threshold \[imipramine, amitriptyline, doxepin, nortriptyline, maprotiline, chlorpromazine, clozapine, foscarnet, ganciclovir, ritonavir, amphetamines, phencyclidine, ketamine, gamma-hydroxybutyrate (GHB), alcohol, theophylline\]
- Barbiturates, benzodiazepines, meprobamate, chloral hydrate in the past 4 weeks
- Acute skin disease
- History of magnetic or electrical stimulation

- Masking Details
- Study investigators will utilize the generated randomization schedule to provide active tDCS and sham stimulation codes that will be entered into the tDCS device (by the caregiver) prior to each session. These numeric codes will be random numbers and not distinct to the study group assignment, protecting the blind. One of the study investigators who will program the tDCS device will remain unblinded and will not be involved in any treatment outcome assessments. All other study staff, including the PI and the co-PIs remain blind. Parents, participants, and ABA providers will also remain blind.
