Report on Fish Oil Affects on Adhd


The study looked at whether DHA supplements could improve information processing, hyperactivity and conduct behaviour problems.   Children without any learning disabilities aged 8 to 10 were given either a fish oil supplement containing DHA fatty acids or a placebo (olive oil). The children were tested before any supplement was given and then tested after 16 weeks by using a matching familiar figures test (MFFT) and a strengths and difficulties questionnaire (SDQ). For each test, results indicated that differences between groups in week 16, when week 0 was used as a confound, was not significant. Only correct responses of the MFFT were significant, but as latency of the responses was not significant, general information processing was not improved. It was discussed that future studies should look at this in children given DHA while breast feeding. It was also discussed that hyperactivity and conduct behaviour should be analysed in either a digit span test or by using different people to fill out the questionnaire.


The study focuses on the subject of whether omega 3 supplements in healthy children’s daily diets could improve their information processing (thus attention) but also reduce conduct behaviour problems and hyperactivity. To do so, supplements in fish oil which contains omega 3 fatty acids or a placebo (olive oil) were given randomly to 401children ranging from the age of 8 to 10.
Past studies have looked at the effects of increasing omega 3 fatty acids in children with attention deficit hyperactivity disorder (ADHD)’s diet could decrease their symptoms. These children are especially interesting to researchers as the symptoms include extreme inattention and/or impulsivity and hyperactivity (Biederman J, 1998).
Stevens, Zentall, Deck, Abate, Watkins, Lipp and Burgess, in 1995, found that subjects with ADHD showed lower plasma concentration of essential fatty acids (containing omega 3). However the precise reason for the lower...
