Brief Summary:
In a double-blind, placebo-controlled 16-week trial investigators administered daily doses of either youths with autism spectrum disorders.ARA and DHA supplementation significantly improved communication as well as social withdrawal symptoms. This pilot study provides the first evidence that supplementation with larger ARA doses added to DHA improve impaired social interaction in youths with Autism Spectrum Disorders (ASD).

Condition or disease Intervention/treatment Phase

Arm Intervention/treatment
Experimental: Placebo-controlled trial Other: Aravita including arachidonic acid and docosaheaenoic acid
Nine of 13 Participants were treated with 6 capsules of Aravita per day for 16-week trial, remaining 4 participants aged under 12 years received 3 capsules per day.

Primary Outcome Measures :
  1. Aberrant Behavior Checklist-community (ABC) [ Time Frame: Pretreatment and at 4 weeks after intervention for 16-weeks trial ]
    ABC is used to estimate abnormal behavior, including 5 subscales, irritability, social withdrawal, stereotypy, hyperactivity, and inappropriate speech

Secondary Outcome Measures :
  1. Social Responsiveness Scale (SRS) [ Time Frame: pretreatment and at 4 weeks after intervention for 16-weeks trial ]
    The SRS is assessed the severity of social communication impairment in any population.
