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.
Brain Changes = Sleep Problems. When researchers compared the 13 patients' results with 27 healthy people, they found very different patterns. The 13 sleep-problem patients had far fewer brain cells -- neurons -- that produce the chemicals dopamine and acetylcholine.And those with fewer such neurons had the worst sleep problems. Patients who had the lowest dopamine levels talked and thrashed while they slept.hen researchers compared the 13 patients' results with 27 healthy people, they found very different patterns.
