Document Summary

Brain activity during sleep has been extensively studied using eeg. Sleep can be subdivided into 5 distinct stages, each exemplified by distinct eeg activity. Five stages include: one stage of rapid eye movement (rem) and several stages of nrem sleep. An eeg is a device which is used to infer electrical activity of specific brain regions. Longer time takes to fall sleep= longer sleep latency. Shorter rem periods & more frequent periods of arousal= awakening. When you get older, it takes longer to fall asleep= more interrupted sleep among the elderly. In elderly adults, several changes in sleep are commonly observed: sleep onset is delayed (longer sleep latency, deep sleep and rem sleep periods are shortened, awakenings (periods of arousal) are more common. Sleep disturbances are common in elderly individuals often occurring in connection with other medical problems. As many of 50% of older adults report some form of sleep disturbance (many of disturbances are not formally diagnosed)
