ADHD Omega-3 Deficiency?

I just read about a story that may link ADHD symptoms to an Omega-3 Deficiency.  Could ADHD be atributed to diet - specifically intake of fatty acids?  As the article below points out, this certainly appears to be a possibility. Do you think that this case study has any relevance? Or is this just more hot smoke?

Fatty acid status and behavioural symptoms of Attention deficit hyperactivity disorder in adolsecents: a case-control study.

RESULTS:

Results showed that ADHD adolescents consumed more energy and fat than controls but had similar anthropometry. ADHD children consumed equivalent amounts of omega-3 and omega-6 fatty acids to controls, however they had significantly lower levels of docosahexaenoic acid (DHA, 22:6n-3) and total omega-3 fatty acids, higher omega-6 fatty acids and a lower ratio of n-3:n-6 fatty acids than control subjects. In addition, low omega-3 status correlated with higher scores on several Conners’ behavioural scales. C

CONCLUSION:

These data suggest that adolescents with ADHD continue to display abnormal essential fatty acid profiles that are often observed in younger children and distinctly different from normal controls of similar age. Further these red blood cell fatty acid differences are not explained by differences in intake. This suggests that there are metabolic differences in fatty acid handling between ADHD adolescents and normal controls. The value of omega-3 supplements to improve fatty acid profiles and possibly behaviours associated with ADHD, need to be examined.
