The main cause of narcolepsy is a lack of hypocretin (orexin), a neurotransmitter in the brain that controls REM sleep and waking. The sleep-wake cycle is upset by low hypocretin levels, which can lead to excessive daytime drowsiness, unexpected sleep episodes, and, in certain situations, cataplexy. This insufficiency may be caused by brain damage, autoimmune reactions, or genetic reasons. Common vitamin or mineral deficiencies do not cause narcolepsy, although poor general health and sleep patterns might exacerbate symptoms. In cases that have been diagnosed, doctors may recommend wakefulness-promoting drugs, such as Waklert 150mg, in addition to lifestyle modifications to enhance alertness and control daytime drowsiness.
