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.
1 The overnight sleep in narcolepsy is usually very fragmented and of poor quality, but people with idiopathic hypersomnia tend to sleep continuously through the night.  Short daytime naps in narcolepsy tend to be refreshing, but naps in idiopathic hypersomnia are more like long sleeps and are not refreshing.
