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.
Persistent daytime sleepiness occurs in all people with narcolepsy. Narcolepsy can also cause cataplexy, brief episodes of muscle weakness triggered by strong emotions. In addition, narcolepsy can cause fragmented sleep with vivid dreams, and hallucinations and brief paralysis when dozing off or waking up. These symptoms typically begin between ages 10 and 20.
