Due to research indicating that Modalert 200 modafinil may improve executive and working memory, it is well-liked by those looking to improve their cognitive abilities. But each person reacts to modafinil differently, and some users may have adverse effects including headaches, nervousness, or trouble sleeping. Both perceived memory function and cognitive performance may be impacted by these adverse effects. There is insufficient data to conclude that modafinil directly impairs memory.
