A randomised controlled trial of fish oil for treatment of aggressive behaviour in young people

This study is testing whether fish oil supplements can reduce aggressive behavior in children and teenagers who have been diagnosed with a disruptive behavior disorder, such as Oppositional Defiant Disorder or Conduct Disorder. Fish oils are a popular supplement, but no study has looked specifically at whether they help with aggression in young people. Participants will take either fish oil or a placebo (dummy supplement) to see if there is a difference in how often and how severely they act aggressively. You may be eligible if: - Your child is between 6 and 17 years of age - Your child shows obvious aggressive behavior - Your child has been diagnosed with Oppositional Defiant Disorder or Conduct Disorder You may NOT be eligible if: - Your child is 18 or older - Your child has been diagnosed with autism or another developmental disorder - Your child has been diagnosed with intellectual disability - Your child has schizophrenia, bipolar disorder, PTSD, or a substance use disorder Talk to your doctor about whether this trial might be right for you.
