How does exercise help Attention deficit-Hyper Activity Disorder (ADHD) symptoms?

Exercise therefore actually acts like medication that is prescribed for ADHD. It also helps to less the need for impulsivity and the cravings for immediate gratification as it works towards waking up the main function of the frontal cortex, which will then allow for delay, better choices and more time to evaluate consequences.
