A randomized, double-blind, placebo-controlled trial of docosahexaenoic acid supplementation in children with attention-deficit/hyperactivity disorder.
OBJECTIVE To determine whether docosahexaenoic acid ( DHA ) supplementation for 4 months decreases the symptoms of  attention-deficit/hyperactivity disorder ( ADHD ) .  STUDY DESIGN Sixty-three 6- to-12-year-old children with ADHD , all receiving effective maintenance therapy with stimulant medication , were assigned r and omly , in a double-blind fashion , to receive DHA supplementation ( 345 mg/d ) or placebo for 4 months . Outcome variables included plasma phospholipid fatty acid patterns , scores on laboratory measures of inattention and impulsivity ( Test of Variables of Attention , Children 's Color Trails test ) while not taking stimulant medication , and scores on parental behavioral rating scales ( Child Behavior Checklist , Conners ' Rating Scale ) . Differences between groups after 4 months of DHA supplementation or placebo administration were determined by analysis of variance , controlling for age , baseline value of each outcome variable , ethnicity , and ADHD subtype . RESULTS Plasma phospholipid DHA content of the DHA-supplemented group was 2.6-fold higher at the end of the study than that of the placebo group ( 4.85 + /- 1.35 vs 1.86 + /- 0.87 mol % of total fatty acids ; P < .001 ) . Despite this , there was no statistically significant improvement in any objective or subjective measure of ADHD symptoms . CONCLUSION A 4-month period of DHA supplementation ( 345 mg/d ) does not decrease symptoms of ADHD
