Efficacy of Phosphatidylserine Enriched With n-3 PUFA Supplementation on ADHD in Children With Epilepsy (AGPIn3)
Efficacy of Phosphatidylserine Enriched With Polyunsaturated n-3 Fatty Acid Supplementation on Attention Deficit Disorders in Children With Epilepsy. A Randomized Double-blind Placebo-controlled Trial
Our project aims to develop a new therapeutic approach in epilepsy-associated attention disorders in children, through evaluation of the clinical impact of dietary n-3 fatty acids, containing eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) conjugated to a phospholipid vector. The primary objective is to evaluate the efficacy of a PUFA supplementation (PS-Omega 3), after 12 weeks of treatment, on attention disorders in children with epilepsy. Secondary objectives include:
- To evaluate the impact of a supplementation of PS-Omega 3 on quality of life.
- To evaluate the impact of a supplementation of PS-Omega 3 on serum and erythrocyte lipid profiles.
- To assess the tolerance of a supplementation of PS-Omega 3.
- To assess the impact of a supplementation of PS-Omega 3 on the frequency of seizures.
To describe the impact of a supplementation of PS-Omega 3, at 24 weeks,
- on attention disorders in children with epilepsy,
- on quality of life,
- and on serum and erythrocyte lipid profiles. This study will recruit 272 subjects aged 6- 16 years, suffering from epilepsy (any type) and attention deficit hyperactivity disorder (ADHD) (inattentive or combined type) according to DSM V criteria in 12 clinical sites in France.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: PS-OMEGA 3, capsules twice daily
Vayarin®, supplementation of n-3 PUFA: each capsule contains 8.5 mg of docosahexaenoic acid (DHA), 21.5 mg of eicosapentaenoic acid (EPA) and 75 mg of phosphatidylserine.
|
Two capsules will be swallowed twice daily, 20 to 30 minutes prior to breakfast and dinner, during 12 weeks, between visit 1 and visit 2. At the end of this period, active product will be continued, at the same dose, for a 12 week-open label period. All patients will be administered the active product. |
Placebo Comparator: PLACEBO, capsules twice daily
The placebo will be made of cellulose and a small amount of fish powder to maintain the double-blind in odor and taste.
The supplementation in n-3 PUFA in the placebo group may be considered as negligible.
Placebo will be administered as indistinguishable capsules, identical to the active product.
|
Two capsules will be swallowed twice daily, 20 to 30 minutes prior to breakfast and dinner, during 12 weeks, between visit 1 and visit 2.

Primary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Reduction of the ADHD-rating scale IV inattentive subscore in subjects assigned to supplementation of PS-Omega 3 in comparison with the placebo group after 12 weeks of treatment.
Time Frame: 12 weeks
|
The ADHD Rating Scale-IV quantifies each of the 18 symptoms of ADHD on a 0 to 3 scale, with a maximum score of 54 points.
Nine of the 18 items score for inattention while the nine others assess hyperactivity with a maximum of 27 points each.
The discriminative value of these two subscales was validated, allowing their individual use.
