The Lasting Effects of Adolescent Dopamine on Impulsivity and Aggression

A study conducted by researchers at Columbia University Irving Medical Center has identified a sensitive developmental period during adolescence that influences adult impulsivity, aggression, and dopamine function in mice. The study suggests that stimulant drug exposure during this period can have harmful consequences for healthy individuals but potentially beneficial effects for those with dopamine dysfunction. The findings highlight the need for a careful risk/benefit evaluation of drug exposure prior to adulthood.
