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.
Sleep attacks â falling asleep suddenly and without warning â are also common in people with narcolepsy. They may occur at any time. The length of time a sleep attack lasts will vary from person to person. Some people will only have microsleeps lasting a few seconds, whereas others may fall asleep for several minutes.
