Cataplexy (sudden muscle weakness), extreme daytime sleepiness, frequent, erratic sleep bouts, hallucinations, and sleep paralysis are all possible symptoms of severe narcolepsy. These symptoms can negatively affect relationships, employment, education, and general quality of life. Sometimes, the persistent weariness and shame might cause melancholy or social disengagement. The treatment of excessive daytime sleepiness in narcolepsy sometimes involves the use of Modvigil 200, a larger dose of modafinil. By encouraging wakefulness and enhancing alertness, it enables patients to maintain their functionality all day long. Nevertheless, it doesn't treat narcolepsy; ongoing care and assistance are required.
