Modafinil is a prescription eugeroic (wakefulness-promoting agent) that increases levels of dopamine, norepinephrine, and histamine in the brain. Its relevance to healthspan is indirect and speculative, primarily through its off-label use for enhancing cognitive function, focus, and productivity. There is no direct evidence that it targets fundamental aging pathways or extends lifespan.
Verdict
A high-risk cognitive tool, not a core healthspan intervention.
