Inside the ADHD Brain: Impulsivity & Impulsive Behavior

Why do people with ADHD act so impulsively? How can you solve problems associated with impulsive behavior, and even stop it? The thalamus is the interior area of the brain that operates like a gate, sending signals to allow and stop behaviors as is appropriate. In ADHD brains, the limbic-hippocampal connections relaying these warning signals from the thalamus to the frontal cortex are impaired. It’s as if the gate is broken, and behavior doesn’t get suppressed when it should. Learn more the underpinnings of impulsivity in the ADHD brain here.
