The brain's reticular activating system (RAS), which governs wakefulness and attention, is the primary regulator of alertness and arousal. These states are maintained in large part by neurotransmitters such as acetylcholine, norepinephrine, and dopamine. Alertness is also influenced by outside variables including stimulants, sleep habits, and light exposure. Modalert 200, also known as modafinil, is a wakefulness-promoting stimulant that is used to treat narcolepsy and shift work sleep disorder. By raising dopamine levels in the brain, Modalert improves alertness and keeps people focused and awake. Although it should be administered under medical supervision, it is frequently used off-label to improve cognitive function.
