Adderall is a prescription medication commonly used to treat Attention Deficit Hyperactivity Disorder (ADHD) and narcolepsy. Containing a mix of amphetamine and dextroamphetamine, Adderall works by increasing the levels of neurotransmitters, such as dopamine and norepinephrine, in the brain. This mechanism helps improve focus, attention, and impulse control in individuals with ADHD.
