דגשים של גיא: המחקר משתמש במגוון הגדרות לתתי קבוצות בספקטרום של ADHD. על מנת לפשט את המסקנות ניתן לאמר שלא רק שמחסור באומגה 3 גורם לחוסר קשב וריכוז, אלא שתסמיני משנה המופיעים אצל תתי אולכוסיות של ADHD כמו חוסר ויסות רגשי, רגזנות, עצבנות ואי קבלת סמכות גם הן נגרמות לפחות באופן חלקי ממחסור באומגה 3 ועודף אומגה 6.

Abstract
Background: In addition to the core symptoms, attention deficit hyperactivity disorder(ADHD) is associated with poor emotion regulation. There is some evidence that children and young adults with ADHD have lower omega-3 levels and that supplementation withomega-3 can improve both ADHD and affective symptoms. We therefore investigated differences between ADHD and non-ADHD children in omega-3/6 fatty acid plasma levels and the relationship between those indices and emotion-elicited event-related potentials(ERPs).
Methods: Children/adolescents with (n=31) and without ADHD (n=32) were compared in their plasma omega-3/6 indices and corresponding ERPs during an emotion processing task.
Results: Children with ADHD had lower mean omega-3/6 and ERP abnormalities in emotion processing, independent of emotional valence relative to control children. ERP abnormalities were significantly associated with lower omega-3 levels in the ADHD group.
Conclusions: The findings reveal for the first time that lower omega-3 fatty acids are associated with impaired emotion processing in ADHD children.
