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.
A person with narcolepsy has excessive daytime sleepiness, with repeated episodes of sleep attacks, falling asleep involuntarily at inappropriate times, often several times every day. Narcolepsy can develop at any age, but it commonly starts either during the teenage years or in middle age.
