Document Summary

Dr hobson is looking at an eeg tracing from a patient in his sleep. About 15% of adults complain about this: insomnia, most common, difficulty in getting to sleep or staying asleep, most people fall short on expectations. Activation remains high and normal sleep cycle fails to develop: sleep apnea, interruption in breathing during sleep, normal, but people with sever disorder do not start breathing unless they wake up, severe: Depleted supply of hypocretins (involved in arousal levels and wakefulness) Often triggered by strong emotions: parasomnia, various sleep-related problems, sleep walking rare in adults. Many walking actions performed out of awareness. Occurs in stage 4 (not a part of a dream) Walking by motor memory most of the time tends to run in families: sleep talking. Occurs in lighter stages (1 or 2) Sensitive to external world: sleep talking and walking have no real cause, night terrors. When asleep, child suddenly sits up, screams.
