The reason I became interested in the adolescent brain is twofold. Firstly, we know that most adult mental disorder has its onset at some point during the teenage years, so if you look at disorders like anxiety disorders, depression, addictions, eating disorders, almost all of them will have their onset some time during the teenage years. Schizophrenia, as you might know, is a very horrific psychiatric condition that's characterized by delusions, like being paranoid and thinking that people are out to get you, and hallucinations like imagining that people are talking to you inside your head, hearing voices. That has its onset at the end of adolescence, normally in the early 20s, on average.
At times, it seems like teens don't think things through or fully consider the consequences of their actions. Adolescents differ from adults in the way they behave, solve problems, and make decisions.
There is a biological explanation for this difference. Studies have shown that brains continue to mature and develop throughout childhood and adolescence and well into early adulthood.
Scientists have identified a specific region of the brain called the amygdala that is responsible for immediate reactions including fear and aggressive behavior.
This region develops early. However, the frontal cortex, the area of the brain that controls reasoning and helps us think before we act, develops later. This part of the brain is still changing and maturing well into adulthood.
Other changes in the brain during adolescence include a rapid increase in the connections between the brain cells and making the brain pathways more effective.
Nerve cells develop myelin, an insulating layer that helps cells communicate. All these changes are essential for the development of coordinated thought, action, and behavior.
Changing Brains Mean that Adolescents Act Differently From Adults Pictures of the brain in action show that adolescents' brains work differently than adults when they make decisions or solve problems.
Their actions are guided more by the emotional and reactive amygdala and less by the thoughtful, logical frontal cortex. Research has also shown that exposure to drugs and alcohol during the teen years can change or delay these developments.
Based on the stage of their brain development, adolescents are more likely to: It also doesn't mean that they shouldn't be held responsible for their actions. However, an awareness of these differences can help parents, teachers, advocates, and policy makers understand, anticipate, and manage the behavior of adolescents.
