Final answer:
Adderall, a medication used to treat ADHD, contains amphetamine compounds. It is a CNS stimulant that enhances neurotransmitter activity, leading to increased focus and reduced impulsiveness in patients.
Step-by-step explanation:
Adderall is a widely prescribed medical treatment for attention deficit hyperactivity disorder (ADHD) which contains amphetamine compounds. This medication is categorized as a central nervous system (CNS) stimulant and works by increasing neurotransmitter activity in the brain, particularly affecting impulse control within the prefrontal cortex and basal ganglia. Although ADHD is characterized by symptoms of hyperactivity and impulsivity, stimulant medications like Adderall and others, such as methylphenidate (known under brand names such as Ritalin, Concerta, and Daytrana), are commonly used to help enhance focus and reduce impulsiveness in patients by promoting calmness.
