In adults, blood pressure is considered normal if the top number (systolic pressure) is between 90 and 120 and the bottom number (diastolic) is between 60 and 80. There are several classes of blood pressure medications. Each class lowers blood pressure in a different way.
For other uses, see Narcolepsy (disambiguation). Narcolepsy is a long-term neurological disorder that involves a decreased ability to regulate sleep-wake cycles. Symptoms include periods of excessive daytime sleepiness that usually last from seconds to minutes and may occur at any time.
People with narcolepsy experience frequent excessive daytime sleepiness, comparable to how people who don't have narcolepsy feel after 24â48 hours of sleep deprivation, as well as disturbed nocturnal sleep which often is confused with insomnia.
