“Despite the fact that ADHD is a fuzzy clinical entity, we have made progress in understanding what is happening in the brain of most people with ADHD. The current consensus is that ADHD is a deficit of executive functions. The frontal lobes carry out many critical functions, some considered executive functions: they include being able to focus your attention, maintain focus, switch among tasks, filter out distractions, and impulse control. Executive function includes the ability to weigh the probable outcomes of your behavior and then make high-level decisions about how you will behave.”
