BIO 337 Lecture Notes - Lecture 14: Sleep Onset Latency, Polysomnography, Tension Headache
Document Summary
Prevalence of insomnia symptoms rise with age. Headache and pain - some of the most common. Chronic insomnia = predictor of later psychiatric problems (morbidity) Insomnia disorder: a subjective experience ( > 3 months: the individual reports 1+ following sleep-related complaints. 5. ) daytime sleepiness - not as common for people with chronic insomnia to complain about (possible prompt investigation into other diagnoses) 7. ) proneness for errors/accidents at work or while driving. 8. ) tension headaches, and/or gi symptoms in response to sleep loss. The problem: sleep state misperception in chronic insomnia. When tested with polysomnogram - doesn"t look like anything is wrong (even when they complain of poor sleep) Sensitivity vs specificity of measure to discriminate between normal and chronic insomnia. Total sleep time, latency to persistent sleep, mid-wake after sleep onset, terminal wake time. Sleep efficiency = how much the sleep is fragmented. Sensitivity = in a population, if everyone has the problem, include everyone, how many will you exclude.
