Omega-3 fatty acids are among the most commonly used CAM (Complementary Alternative Medical) therapies, and have been reported to be currently used by 28.7% of children with autism. Two published case series noted that families reported large improvements in the core feature of autism when children were given omega-3 fatty acids. Low levels of omega-3 fatty acids have been noted in children with autism, which suggests normalizing the omega-3 fatty acid levels could produce improvements in the symptoms seen in many children with autism.
This study is a 12-week randomized, double blind, placebo-controlled clinical trial for 24 male and female children aged 3 to 8 years with autism. Patients who are currently using omega-3 would need to discontinue omega-3 fatty acids for 8 weeks before they are able to participate in the study. All study participants who meet all inclusion and no exclusion criteria at the initial screening visit and sign the consent form will then complete baseline assessments of the outcome measures (validated instruments of hyperactivity, communication, social interaction, and behavior) and be randomly assigned to 12 weeks of omega-3 fatty acids at a dose of 1 gm per day or an identical placebo. The child's behavior will be measured and evaluated at the MIND Institute at the beginning of the study and at study closing. All study families will come in for a follow-up visit at weeks 4 and 8 to assess medication compliance and side effects to study medication.
After 12 weeks of treatment, all outcome measures including laboratory tests and side effect profiles will be repeated. All patients who complete the study will receive a 12-week supply of omega-3. This would also provide patients who were on placebo with active medication. No follow-up visits are needed once the patient finishes the double-blind portion of the study.

- Group-specific and Comparison of Change in Aberrant Behavior Checklist-Hyperactivity Subscale Score (Active Omega-3 Group Only, Placebo Group Only and Comparison Between Groups) [ Time Frame: Baseline and 1 year ]Hyperactivity subscale of Aberrant Behavior checklist (ABC-H): measure of assessing changes in symptoms of hyperactivity in children with autism (survey that was normed on a developmentally delayed population of children and adults and is usually completed by a parent or caregiver. Items are rated on a 4-point scale from "no problem" to "major problem"). ABC-H Subscale Score ranges from 0 (best) to 45 (worst). A negative change signifies improvement.
- Change in Percentage of Serum Omega-3 Fatty Acids [ Time Frame: Baseline and 1 year ]Change in percentage calculated as (100% * ((One Year - Baseline)/Baseline)
- Change in Serum TNFα (Cytokine) Level [ Time Frame: Baseline and 1 year ]
