Does modvigil improve cognitive function?

Modvigil 200 (a modafinil‑based medicine) can sometimes improve aspects of cognitive function, especially alertness, episodic memory, and working memory in certain conditions, but the effects are generally small and mixed. Some clinical studies show that a 200 mg dose of modafinil may enhance episodic memory and working memory in people recovering from depression, and it may help with attention or higher‑order task performance in other settings.
