Insomnia Sleep Disorder

In order to appreciate the significance of insomnia, it is useful to be aware of the importance of sleep to maintenance of a healthy organism. There exists a large body of professional literature on the subject of sleep function, behavior, and malfunction, starting with Freud's Interpretation of Dreams, but by no means ending there; Freud emphasized the psychological features of sleep and dreaming in his classic work. But since Freud there has been marked disagreement over whether and to what extent dreaming is primarily psychological or physiological. The discovery in 1952-53 of rapid eye movement (REM) during dreams and non-REM sleep (NREM) in nondreaming periods, noted in Aserinsky and Kleitman's work (1953; cited by Jones, 1978), fostered a significant body of research into the connection rather that distinction between the physiology and psychology of sleep.

Conditions attendant to insomnia (e.g., RLS, PLMD, anxiety) also appear more frequently in elderly populations. But it is important to recognize that the experience of less sleep among aging populations need not be considered pathological. Changes in sleep patterns, including but not limited to the decrease in the number of hours slept, may be a consequence of the natural aging process. That is why the factor of interference with waking-hours activity is so important in determining whether the absence of sleep is to be considered insomnia. On the other hand, sleep-disorder experts say that if characteristics of insomnia present themselves for longer than three weeks, it is time to see a physician to take care of the underlying causes, whether physical or psychological or both. Just as insomnia may be an effect that derives from a variety of causes, so may the effects of insomnia vary in both degree and kind, depending on the individual involved. Those suffering from acute insomnia experience sleepiness, negative mood, and performance impairment d
