Investigation of Psychophysiological Response to Aversive Stimuli Over Time With Omega-3

Investigation of Psychophysiological Response to Aversive Stimuli Over Time With Omega-3

This study investigates the psychophysiological responses to aversive stimuli in a population of 133 children clinically diagnosed with conduct disorder (CD) and/or attention-deficit/hyperactivity disorder (ADHD). Participants were administered with either omega-3 or placebo for a period of 6 months and were exposed to three stimuli every three months: 1) a loud sound, 2) threatening photographs from the International Affective Picture System (IAPS), and 3) the Trier Social Stress Task (TSST). Participants' psychophysiological features of heart rate and galvanic skin conductance were measured and analyzed in relation to their omega-3/placebo condition clinical diagnosis.

2. Subjects who fulfil all criteria for a DSM-IV diagnosis of ADHD, conduct disorder, or oppositional defiant disorder
3. Subjects with willingness to participate in a randomized, double-blind controlled trial
4. Subjects with complete written, informed parental consent and child assent

Exclusion Criteria:

1. Subjects who have IQ in the below 70
2. Subjects who are younger than 7 years old or older than 16 years old
3. Those without written parental consent
