Psychiatrist Richard Friedman argues in the New York Times that there are aspects of natural brain development that make teenagers more prone to both experiencing intense anxiety and engaging in risky behaviors. Eventually, says Friedman, the rational, executive brain functions become more developed. He then suggests that the mechanistic action of ADHD drugs may suppress that important next-stage development. “Might our promiscuous use of stimulants impair the ability of adolescents to suppress learned fear — something that is a normal part of development — and make them more fearful adults?” asks Friedman.
