Supplementation of Phosphatidylserine (PS) and n-3 Long Chain Fatty Acids (EPA, DHA) in Children With ADHD

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00382616

Brief Summary:
To determine whether supplementation of omega-3 long-chain polyunsaturated fatty acid conjugated to phosphatidylserine rather than triglycerides (fish oil) could affect Attention-deficit/hyperactivity disorder symptoms in children.

Condition or disease Intervention/treatment Phase
Attention-Deficit/Hyperactivity Disorder Drug: Phosphatidylserine-Omega3 Phase 2

Detailed Description:

BACKGROUND Attention-deficit/hyperactivity disorder (ADHD) encompasses a broad constellation of behavioral and learning problems, clinically describes inattentive, impulsive, and/or hyperactive children. These patients are characterized by low blood LC-PUFA (LC-PUFA) levels; however the LC-PUFA supplementation effect on ADHD symptoms is not clear.

METHODS Eighty-three ADHD children (3:1 boys:girls), 8-13 years old, were assigned in a randomized, double-blind, placebo-controlled parallel design to receive 250 mg/d of eicosapentaenoic acid + docosahexaenoic acid provided as phosphatidylserine (300 mg/d PS-Omega3), or fish oil or placebo for 3 months. Stimulant medication or other dietary supplements were prohibited. The measured outcomes were inattention and impulsivity, evaluated by Test of Variables of Attention (TOVA) and blood lipids profile.
