To explain this stuff to the non-specialist, I use this comparison...
Executive functions are to the brain what the driver is to the car. When the driver is in top shape, he can adjust for minor problems in the car (a burned out headlight, an awkward crack in the windshield), follow a regular maintenance plan (self-care - sleep, food, check-ups, etc.), AND know when there's a more major problem that needs immediate assistance.
When the executive functions are impaired... its just like an impaired driver! The car runs just fine, thank you - good brakes, clear windshield, motor runs great, tranny was just serviced... but the driver is over .08 (the legal limit here)... and that means TROUBLE.
Too slow to hit the brakes, too hard on the gas, doesn't leave enough room for cornering, weaving all over the road...
You know the routine - and you get the picture!
