Brief Summary

N-3 polyunsaturated fatty acids(N-3 PUFAs) is important in balancing the immune function and crucial for the developing brain. Deficiency in n-3 PUFAs might be linked to the poor cognitive performances resulting in inattention and hyperactivity in youth with attention deficit hyperactivity disorder (ADHD). N-3 PUFAs appears to be a promising treatment that is safe, beneficial to youth with ADHD. In this proposal, investigators aim the test the hypothesis that n-3 polyunsaturated fatty acids will be more effective than placebo in improving cognitive function in youth with ADHD after 12 weeks of intervention.

Outcome Measures

Primary Outcomes (1)

  • Changes in Continuous Performance Test Raw Scores at 12 weeks

    Correct Detection: This indicates the number of times the client responded to the target stimulus. Higher rates of correct detections indicate better attentional capacity. Reaction times: This measures the amount of time between the presentation of the stimulus and the client's response. Omission errors: This indicates the number of times the target was presented, but the client did not respond/click the mouse. High omission rates indicate that the subject is either not paying attention (distractibility) to stimuli or has a sluggish response. Commission errors: This score indicates the number of times the client responded but no target was presented. A fast reaction time and high commission error rate points to difficulties with impulsivity. A slow reaction time with high commission and omission errors, indicates inattention in general.
