Which of the following is NOT a common ADHD treatment option?

• A. Stimulants.
• B. Norepinephrine reuptake inhibitors.
• C. Alpha-2 agonists.
• D. Benzodiazepines.

Answer: (D)

ADHD treatments aim to boost catecholamine signaling in the prefrontal cortex to improve attention, impulse control, and executive function. Stimulants increase dopamine and norepinephrine levels directly and are a common first-line option. Non-stimulants like norepinephrine reuptake inhibitors specifically raise norepinephrine to help with attention and behavior. Alpha-2 agonists (guanfacine, clonidine) can reduce hyperactivity and improve impulse control, especially in kids or when there are comorbid tics or sleep issues. In contrast, benzodiazepines depress CNS activity and produce sedation, cognitive slowing, and dependence risks, which do not address the core ADHD symptoms and can actually impair attention. They are therefore not used as a routine treatment for ADHD, though they may be used for coexisting anxiety or sleep problems in some cases.
