A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to evaluate the effects of oral Ultramicronized-Palmitoylethanolamide (PEA) on alleviating anxiety and depressive symptoms in individuals with Level 1 Autism Spectrum Disorder (ASD). It will assess the safety, tolerability, and biological mechanisms of PEA over a 12-week treatment period. The study will recruit eligible participants aged 18-35 who can communicate in Italian and provide informed consent. The focus is on addressing the unmet clinical needs of autistic individuals who do not respond well to conventional treatments.

Why it matters

Potential benefit: If successful, this study could provide a new therapeutic option for managing anxiety and depressive symptoms in autistic individuals.

How similar studies have gone: While the therapeutic potential of endocannabinoid modulation is gaining interest, this specific approach using PEA in this population is relatively novel and has not been extensively tested.
