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.
Still other persons with the disorder may experience severe sleepiness or have severe cataplexy (with one or more episodes of cataplexy per day). The basic cause of narcolepsy is not known. It is not a fatal disorder in itself but it can lead to fatalities. For example, a narcoleptic may fall asleep while driving.
