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.
Narcolepsy does not actually belong to the group of excessive sleeping disorders. It is a neurological disorder that causes excessive sleepiness and interferes with normal activities of daily living. People with narcolepsy may have trouble getting to sleep at night and then find fall asleep during the day. Narcoleptics may also develop sudden weakness of the muscles and experience episodes of sleep paralysis. Another neurological disorder, restless leg syndrome, makes it difficult to sleep.
