Where it strikes
Medical treatment
- Parent-training programmes (Incredible Years, Triple P) for younger children trials support
- Multisystemic therapy for adolescents — a large UK trial found no advantage over usual services mixed evidence
- treat co-existing ADHD — stimulants also reduce aggression
- Risperidone for severe aggression — weight gain and metabolic effects mixed evidence
- school-based programmes
Natural & lifestyle
- Consistent, warm discipline
- structured activities and sport
- less exposure to violence
Emerging & experimental
- Therapies aimed at callous-unemotional traits
- early home-visiting programmes
Alternative, off-label & anecdotal
Approaches used outside the guidelines, with what their supporters report and what testing has found so far.
- Omega-3 fatty acids — one trial reduced behaviour problems early / small studies
- 'Scared straight' and boot camps — raise later offending not confirmed in trials
- Few-foods elimination diet — studied in ADHD, not conduct disorder mixed evidence
