The brain and aggression: Interventions for reducing interpersonal reactive aggression

Area of Science:

• Neuroscience
• Psychology
• Pharmacology

Background:

• Aggression is a significant societal issue.
• Understanding the neurocognitive underpinnings of reactive aggression is crucial for developing effective treatments.

Purpose of the Study:

• To present a neurocognitive model of reactive aggression.
• To evaluate four potential interventions (mindfulness, cognitive-behavioral therapies, omega-3s, SSRIs) through the lens of this model.

Main Methods:

• The study reviews existing research on the neurocognitive model and the efficacy of the four interventions.
• It examines how these interventions target specific neuropsychological mechanisms.

Main Results:

• All four interventions (mindfulness, CBT, omega-3s, SSRIs) generally support reducing aggression and improving anger regulation.
• Partial support exists for improved reward functioning and response inhibition.
• Each intervention demonstrates adaptive effects on brain function.

Conclusions:

• The neurocognitive model provides a framework for understanding and treating reactive aggression.
• Mindfulness, CBT, omega-3s, and SSRIs show potential for reducing aggression through modifiable neuropsychological mechanisms.
• Further research is needed to fully elucidate the efficacy and mechanisms of these interventions.
