Adderall is primarily used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy. Here's a breakdown of its uses:

1. Attention Deficit Hyperactivity Disorder (ADHD): Adderall is commonly prescribed to manage the symptoms of ADHD in both children and adults. ADHD is a neurodevelopmental disorder characterized by symptoms such as inattention, hyperactivity, and impulsivity. Adderall helps individuals with ADHD by increasing the levels of certain neurotransmitters in the brain, improving attention span, focus, and impulse control.

2. Narcolepsy: Adderall is also used to treat narcolepsy, a sleep disorder characterized by excessive daytime sleepiness, sudden episodes of muscle weakness (cataplexy), hallucinations, and sleep paralysis. Adderall helps individuals with narcolepsy stay awake and alert during the day by stimulating the central nervous system.
