Adderall (amphetamine and dextroamphetamine) is a stimulant that affects chemicals in the brain that are associated with hyperactivity and impulse control. Adderall is used in attention deficit hyperactivity disorder (ADHD).
The cause of Attention-Deficit Hyperactivity Disorder (ADHD) has been linked with the brain's chemical system, not it's structure. Thus, Attention-Deficit Hyperactivity Disorder (ADHD) is a problem with brain chemistry - not brain damage or injury.
