About this study

Official title: The Effects of Eicosapentaenoic Acid (EPA)/ Docosahexaenoic Acid (DHA) Supplementation on Cognitive Control in Children With Attention Deficit Hyperactivity Disorder (ADHD)

Forty children with and 40 children without Attention deficit Hyperactivity Disorder (ADHD) receive Docosahexaenoic Acid (DHA) and Eicosapentaenoic Acid (EPA) or placebo via a dietary intervention. Cognitive control functions are measured with functional Magnetic Resonance Imaging (MRI) before and after the intervention. Behavioural change is monitored with behavioural scales.

Being tested
Eicosapentaenoic acid / Docosahexaenoic acid, Placebo dietary intervention (MUFA) in ADHD group, Placebo dietary intervention (MUFA) in healthy control group
Keywords

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Eicosapentaenoic acid / Docosahexaenoic acidDietary supplement

    Also called EPA, DHA

    650 mg EPA + 650 mg DHA daily

  • Placebo dietary intervention (MUFA) in ADHD groupDietary supplement

    Also called Mono Unsaturated Fatty Acid, Poly Unsaturated Fatty Acid

    Placebo contains mono-unsaturated fatty acids (MUFA) in stead of poly-unsaturated fatty acids (PUFA), same energy value

  • Eicosapentaenoic acid / Docosahexaenoic acidDietary supplement

    Also called EPA, DHA

    650 mg EPA and 650 mg DHA daily

  • Placebo dietary intervention (MUFA) in healthy control groupDietary supplement

    Also called Mono Unsaturated Fatty Acids

    Placebo contains MUFA in stead of PUFA, same energy value

    Measured: Change over 16 week intervention period (pre/post)

  2. Fatty acids status from cheek cells (swabs)

    Measured: Change over 16 week intervention period (pre/post)

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cognitive control task - functional MRI (time frame: change over 16 week intervention period (pre/post)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
