Supplements of the fatty acids omega 3 and 6 can help children and adolescents who have a certain kind of ADHD.
Johnson et al 2009 - Omega-3/omega-6 fatty acids for ADHD: a randomized placebo-controlled trial in children and adolescents.
"For the group as a whole, we did not see any major improvement, but in 35 percent of the children and adolescents who have the inattentive subtype of ADHD called ADD, the symptoms improved so much that we can talk about a clinically relevant improvement," says Mats Johnson, doctoral student at the Sahlgrenska Academy at the University of Gothenburg.
The levels of omega 3 and omega 6 were also measured in blood samples, where those who had a clear improvement of their symptoms also showed a better balance between the blood levels of these two fatty acids.
The dissertation also indicates that a cognitive training method called Collaborative Problem Solving (CPS) can be a good alternative or complement in the treatment of ADHD and oppositional defiant disorder (ODD).
