PSY 4327 Lecture Notes - Lecture 5: Stress Management, Palatine Uvula, Polysomnography
Document Summary
Lecture 5 hypersomnias & parasomnias (february 12, 2016) 4 main symptoms called the narcoleptic tetrad: cataplexy (complete paralysis) is optional, other three are essential. On-off switch in rem is not functioning properly. Evening (6-9) more able to stay awake and be alert. Sleep attacks uncontrollable: hits rem in sleep attack quickly. More frequently than 2 attacks per day. Most people with severe narcolepsy (especially untreated) are not allowed to drive. After a nap, they are okay for a few hours: relieves pressure on rem, serotonin = keeps rem suppressed, hallucinations after staying awake too long is because there is no more serotonin. Even with enough sleep at night, still sleepiness during the day. Even if narcolepsy without cataplexy, they would still have no muscle tone because they reach rem (muscle paralysis) Difference between sleep attack and cataplexy = asleep vs. conscious. Most people have sleep paralysis when they go to bed. Narcoleptics can get it during sleep attacks or naps.
