Modafinil is primarily used to promote wakefulness in individuals with sleep disorders like narcolepsy and sleep apnea. It may also enhance cognitive functions such as decision-making and planning, particularly in complex tasks, and is sometimes used off-label as a "smart drug" to improve focus and productivity in healthy individuals.
