What this trial studies

This clinical trial investigates the effects of high-dose Vitamin B6 supplementation on sensory hyperreactivity and anxiety in autistic adults. Participants will be divided into two groups, one receiving Vitamin B6 and the other a placebo, to assess differences in sensory reactivity and anxiety levels. Additionally, the study will evaluate the impact of Vitamin B6 on sleep quality, ADHD scores, and visual perception tasks related to GABAergic activity. The goal is to determine if Vitamin B6 can improve these aspects of autism.

Who should consider this trial

Good fit: Ideal candidates for this study are autistic adults aged 18 to 60.

Not a fit: Patients who are taking supplements with more than 2mg of Vitamin B6 or GABA agonist drugs may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new, non-invasive treatment option for reducing sensory hyperreactivity and anxiety in autistic individuals.

How similar studies have performed: While there is limited research on high-dose Vitamin B6 for autism, similar studies exploring nutritional interventions have shown promise, making this approach potentially novel.
