Which brain region is most associated with decision-making and impulse control?

The prefrontal cortex sits at the front of the frontal lobes and supports executive functions such as planning, prioritizing, self-control, and working memory. It helps people weigh consequences and resist impulses. This region develops gradually and is not fully mature until the mid-20s in many individuals. Its prolonged development helps explain why judgment and self-regulation improve with age. Damage to this area can change personality and reduce the ability to make sound decisions.
