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.
Patients may sleep for a few minutes during the day, particularly if they are in an awkward position, or for a few hours if they are lying down. Patients often underestimate the duration of their drowsy periods and may not recall clearly their behavior during that time. Narcolepsy affects about 1 in 2,000 people.
