Narcolepsy is a neurological sleep condition that interferes with the brain's capacity to control sleep-wake cycles; it is not a mental illness. Excessive daytime tiredness, unexpected sleep episodes, and occasionally cataplexy (sudden muscular paralysis) are common symptoms of narcolepsy. The underlying cause of narcolepsy is a malfunction in the brain's sleep systems, even though its symptoms can have an impact on mental health by generating worry or sadness. By encouraging wakefulness, medications such as Modalert 200 (modafinil) aid in the condition's management. Although Modalert 200 doesn't treat narcolepsy, it greatly enhances alertness and day-to-day functioning, allowing people to live more stable and fruitful lives when taken as directed.
