Efficacy of Omega-3 and Korean Red Ginseng in Children with Subthreshold ADHD: A Double-Blind, Randomized, Placebo-Controlled Trial

Abstract

Objective: The purpose of the present study was to investigate the efficacy of combined omega-3 and Korean red ginseng supplementation on ADHD symptoms and cognitive function in children with subthreshold ADHD. Method: 120 children from 6 to 12 years with subthreshold ADHD were enrolled in this 12-week, double-blind, randomized, placebocontrolled study. The primary outcome was measured by Attention-Deficit Hyperactivity Disorder Rating Scale (ADHD-RS). Children Behavior Check List (CBCL), and neuropsychological tests assessing attention, memory, and executive function were included as secondary primary outcome measures. Results: Significant effects on the scores of ADHDRS, as well as several subscales of CBCL including ADHD and attention problem subscales were revealed. Conclusion: The combination of omega-3 and Korean red ginseng may have beneficial effects in children with subthreshold ADHD. Increased clinical awareness of ADHD symptoms even at a subthreshold level is needed.
