NCT02477904

Brief Summary

This study will assess the effectiveness of the ketogenic diet (high-fat, low-carbohydrate, and moderate protein) in treating autism spectrum disorder (ASD). Three study groups will be comprised of children (2-21 years of age) based on whether or not they have ASD and receive the ketogenic diet - ASD/ketogenic diet, ASD/non-ketogenic diet, and non-ASD/non-ketogenic diet.

Outcome Measures

Primary Outcomes (1)

  • Change from baseline in core symptoms of ASD

    Assess core autistic symptoms through review/analysis of responses to the following measurement instruments: Autism Diagnostic Observation Schedule - Second Edition (ADOS-2); Asperger Syndrome Diagnostic Scale (ASDS); Childhood Autism Rating Scale (CARS-2); Gilliam Autism Rating Scale (GARS-3); Social Responsiveness Scale - Second Edition (SRS-2); Diagnostic and Statistical Manual IV Text Revision (DSM-IV-TR) and DSM-V ASD criteria; standardized intelligence tests (if available, administered by child's school); and Vanderbilt ADHD Diagnostic Teacher Rating Scale Forms (Vanderbilt).

    Pre- and post-ketogenic diet intervention (at baseline, and after three and six months on the ketogenic diet)

Secondary Outcomes (7)

  • Change from baseline in the number of medications used for ASD management

    Pre- and post-ketogenic diet intervention (at baseline, and after three and six months on the ketogenic diet)

  • Change from baseline in the dosage of medications used for ASD management

    Pre- and post-ketogenic diet intervention (at baseline, and after three and six months on the ketogenic diet)

  • Change from baseline in the number of lab tests ordered for ASD management

    Pre- and post-ketogenic diet intervention (at baseline, and after three and six months on the ketogenic diet)

  • Change from baseline in the number of emergency room or hospital visits for ASD management

    Pre- and post-ketogenic diet intervention (at baseline, and after three and six months on the ketogenic diet)

  • Change from baseline in subject/family satisfaction with the ketogenic diet

    Pre- and post-ketogenic diet intervention (at baseline, and after three and six months on the ketogenic diet)

  • +2 more secondary outcomes

Other Outcomes (1)

  • Possible effects of the ketogenic diet

    Post-ketogenic diet intervention

Study Arms (3)

EXPERIMENTAL

Children (2-21 years of age) diagnosed with autism spectrum disorder (ASD) will receive the ketogenic diet (KD) intervention.

Other: Ketogenic Diet

ACTIVE COMPARATOR

Children (2-21 years of age) diagnosed with autism spectrum disorder (ASD) will not receive the ketogenic diet (KD) intervention.

Other: Ketogenic Diet

non-ASD/non-KD

ACTIVE COMPARATOR

Typically developing children (2-21 years of age) diagnosed as not having autism spectrum disorder (ASD) will not receive the ketogenic diet (KD) intervention.

Other: Ketogenic Diet
