Adderall works by increasing the levels of certain neurotransmitters in the brain, which can help improve focus, concentration, and impulse control in individuals with ADHD. It may also help with wakefulness and alertness in people with narcolepsy, a sleep disorder. It's important to note that Adderall is a controlled substance due to its potential for misuse and addiction. It should only be taken under the supervision of a qualified healthcare professional and as prescribed. Misuse of Adderall can lead to various side effects and health risks, including increased heart rate, high blood pressure, anxiety, and insomnia.
