Omega-3 fatty acid treatment of children with attention-deficit hyperactivity disorder: A randomized, double-blind, placebo-controlled study.
BACKGROUND Although several clinical trials have evaluated the impact of n-3 polyunsaturated fatty acid ( PUFA ) on patients with attention-deficit hyperactivity disorder ( ADHD ) , changes in plasma PUFA composition were not always assessed following n-3 supplementation . Furthermore , no reports are available on the efficacy of n-3 PUFA in Canadian youth with ADHD . OBJECTIVES To determine fatty acid ( FA ) composition , and the efficacy and safety of n-3 PUFA supplementation on ADHD clinical symptoms in French Canadian primary school children . PATIENTS AND METHODS The Strengths and Weaknesses in ADHD and Normal Behaviors ( SWAN ) and Conners ' question naires were used to assess changes in ADHD symptoms in 37 children ( only 26 children completed the study from zero to 16 weeks ) . They were divided into two groups ( A and B ) , and participated in a 16-week , double-blind , one-way , crossover r and omized study . In the first phase , group A received the n-3 PUFA supplement and group B received n-6 PUFA ( sunflower oil ) as a placebo . During the second phase , group B received the active n-3 PUFA supplement that was continued in group A. FA composition and lipid profile were assessed during the phases of the study . RESULTS FA differences between groups were observed in the 26 patients . Supplementation with n-3 PUFA result ed in significant increases in eicosapentaenoic and docosahexaenoic acids in group A , while group B was enriched with alpha-linolenic , gamma-linolenic and homo-gamma-linolenic acids . The n-3 PUFA supplement was tolerated without any adverse effects . A statistically significant improvement in symptoms was noted based on the parent version of the Conners ' question naire from baseline to the end of phase 1 , and this amelioration continued from phases 1 to 2 , although the latter changes from phases 1 and 2 were not statistically significant in any of the subscales except for the subscale measuring inattention in group B. The improvement was greater in patients from group A in phase 1 and in patients from group B in phase 2 . A subgroup of eight patients ( four in each group ) displayed a statistically significant clinical improvement following the administration of the n-3 PUFA supplement , particularly for the inattention and global Diagnostic and Statistical Manual of Mental Disorders , Fourth edition , total Conners ' subscales . CONCLUSIONS A subgroup of children with ADHD who used n-3 PUFA supplements achieved and maintained symptom control . The data of the present study also supported n-3 PUFA  safety and tolerability , but limited changes were noted in the FA profile in French Canadians with ADHD
