While there may be multiple reasons for these problems, sleep disruption could be a potentially correctable cause, and therefore medical evaluation for a possible sleep disorder should be considered under these circumstances.National Heart, Lung, and Blood Institute. ![]() Patients with epilepsy frequently have problems with memory and other aspects of cognitive functioning.Increased slow wave sleep has also been correlated with certain types of learning in one human study. Additionally, enhancement of REM sleep occurs with drugs useful in Alzheimer’s disease. Although the function of REM sleep remains speculative, there is considerable information suggesting that increased REM is correlated with enhanced learning of certain tasks.Very little stage 1 or 2 sleep is regained. Both REM and slow wave sleep are considered to be “essential sleep”, and subjects who are deprived of sleep (at least in the short term) will “rebound” or make up most of the REM and slow wave sleep that are lost. It may be that specific stages of sleep are more important than others.If sleep disruption continues for many nights, however, we can feel our abilities diminishing. We then feel the need to “catch up” and sleep longer for one or more nights. This makes sense as most of us are able to function relatively well after one or two nights of disrupted sleep. Recent studies show that chronic sleep restriction by as little as 2 hours per night can severely impair neurobehavioral functions in normal individuals over a one-to two-week period of time. ![]()
