Official title
Double-Blind Placebo Controlled, Cross-over Trial of Subcutaneous B12 on Behavioral and Metabolic Measures in Children With Autism.
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
We will be testing a specific dietary supplement, methylcobalamin (vitamin B12). Follow-up assessments with our clinical team will take place over the 12-week study period so that we can record any changes in development. The main goal of this study is to determine if subcutaneous injections of vitamin B12 given every three days can positively affect behavior and development in children with autism. Hypothesis: Methylcobalamin injections will improve measures of executive function, speech, and socialization in children with autism, and will be associated with metabolic improvement.
