The effect of lithium on impulsive aggressive behavior in man

Area of Science:

• Neuroscience
• Psychiatry
• Criminology

Background:

• Impulsive aggressive behavior is a significant concern in correctional facilities.
• Previous research has explored pharmacological interventions for aggression, with varying results.

Purpose of the Study:

• To investigate the efficacy of lithium in reducing aggressive behavior among young, nonpsychotic male prisoners.
• To assess the clinical utility of lithium for chronic impulsive aggression.

Main Methods:

• A double-blind, placebo-controlled trial involving 66 male prisoners aged 16-24.
• Participants received daily lithium or placebo for up to 3 months.
• Aggressive behavior was measured by infractions involving violence.

Main Results:

• A statistically significant reduction in aggressive behavior was observed in the lithium group compared to the placebo group.
• Lithium treatment led to fewer violent infractions.

Conclusions:

• Lithium demonstrates a clinically useful effect in mitigating impulsive aggressive behavior in a nonpsychotic prison population.
• Findings suggest lithium as a potential therapeutic option for specific types of aggression.
