Omega-3 Polyunsaturated Fatty Acid Supplementation in Children With Attention-Deficit Hyperactivity Disorder (ADHD)

Area of Science:

• Neuroscience
• Nutritional Science
• Pediatric Health

Background:

• Attention-deficit hyperactivity disorder (ADHD) presents cognitive and behavioral challenges.
• Limited therapeutic options for ADHD drive interest in alternative treatments.
• Omega-3 polyunsaturated fatty acids (PUFAs) play key roles in brain development and function.

Purpose of the Study:

• To evaluate the efficacy of omega-3 PUFA supplementation as an adjunctive treatment for ADHD in children.
• To synthesize findings from primary studies on omega-3 PUFAs and ADHD.

Main Methods:

• A narrative review of six primary studies was conducted.
• Studies were identified through PubMed using specific MeSH and text-word terms.
• Included studies were randomized controlled trials (RCTs) in children with ADHD.

Main Results:

• Outcomes varied, with some studies showing significant improvements in cognition and behavior.
• Other studies found no omega-3 superiority over placebo.
• Specific findings included associations between erythrocyte omega-3 levels and improved attention, and benefits for working memory with eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) supplementation.

Conclusions:

• Omega-3 PUFA supplementation shows potential as an adjunctive therapy for specific ADHD domains.
• Methodological inconsistencies and small sample sizes limit definitive conclusions.
• Further research with standardized protocols and larger samples is needed to confirm the impact of omega-3 PUFAs on pediatric ADHD.
