Adderall is primarily prescribed for the treatment of attention deficit hyperactivity disorder (ADHD) and narcolepsy. Here's how it's used for each condition:

1. Attention Deficit Hyperactivity Disorder (ADHD): Adderall is commonly prescribed to manage the symptoms of ADHD, which include difficulty paying attention, impulsivity, and hyperactivity. It works by increasing the levels of certain neurotransmitters, such as dopamine and norepinephrine, in the brain. By doing so, it helps individuals with ADHD to improve focus, control impulses, and stay organized. Adderall is often a part of a comprehensive treatment plan for ADHD, which may include behavioral therapy, counseling, and other interventions.

2. Narcolepsy: Adderall is also used to treat narcolepsy, a neurological disorder characterized by excessive daytime sleepiness, sudden episodes of muscle weakness (cataplexy), sleep paralysis, and hallucinations upon falling asleep or waking up. Adderall helps to improve wakefulness and reduce excessive daytime sleepiness in individuals with narcolepsy.
