There are many off-label uses of Modafinil, such as cognition enhancement, ADHD, and depression. This prescribed medication was FDA-approved in 1998 and sold under many brand names such as Modalert, Modvigil, etc. It works by increasing neurotransmitters, which contribute to improving brain function. Modafinil also decreases the level of GABA, which causes one to fall asleep, and by reducing it, it helps regulate the sleep cycle.
