Slower brain development puts boys at greater addiction risk, NIH finds

The Washington Times
By Sean Salai

Excerpts:

Boys are more likely than girls to develop addictions because of slower brain development starting at age 9...
Girls had “higher functional connectivity density” than boys in a part of the brain responsible for emotions, social behavior, attention, learning and motivation,...
Published Tuesday in JAMA Network Open, the study also found that girls had superior development in key white matter pathways linked to the self-regulation of nerve impulses.

“Boys are much more likely to engage in risky behaviors such as drug experimentation than girls and are more prone to impulsive behaviors, including truancy [or] driving while intoxicated,” Ms. Volkow told The Washington Times. “It is likely that this vulnerability reflects in part the slower development of brain regions necessary for self-regulation.”
