Narcolepsy is a serious neurological disorder that significantly impacts daily life, though its severity can vary from person to person. It causes excessive daytime sleepiness, sudden muscle weakness (cataplexy), sleep paralysis, and disrupted nighttime sleep, all of which can interfere with work, school, and personal relationships. Left untreated, narcolepsy increases the risk of accidents, especially while driving or operating machinery, and can lead to emotional challenges such as depression or anxiety due to its unpredictable symptoms. While it is a lifelong condition with no cure, proper management through medications like Modalert 200 Australia, lifestyle changes, and support can greatly improve quality of life. Therefore, while it is serious, it can be effectively managed with the right approach.
