Do you ever ask yourself, why does my teenager keep making bad decisions?


Teenagers make bad decisions for various reasons, but the main reason involves the prefrontal cortex development.


The part of the brain behind the forehead, the prefrontal cortex, is one of the last areas of the brain to mature; it is responsible for executive functions such as planning, decision-making, and impulse control, which does not finish developing and maturing until the mid-20s. When this part of the brain is not fully developed, it can lead to behaviors such as lack of judgment, loss of inhibition, and risk-taking.


Early experiences influence the developing brain, healthy brain development comes from providing stable, responsive, nurturing relationships. The prefrontal cortex can be strengthened by teens through social interactions and experiences from their surroundings, and with this, the ability to perform complex functions increases. With the maturation of the frontal lobes, the ability to regulate impulsivity and make better goal-oriented choices will improve.


Some common behaviors that result from a lack of prefrontal lobe maturity include:


  • Impulsivity/ Thrill-seeking

  • Failure to consider consequences

  • Lack of planning

  • Lack of organization

  • Lack of self-control


Some tips for parents to help teens develop their frontal lobe:


  • Encourage your teen to get enough sleep, eat a healthy diet, and exercise regularly

  • Encourage your teen to engage in creative activities such as drawing or painting.

  • Encourage your teen to read books and learn new things.
