Classical sleep disorders of nocturnal enuresis, somnambulism, the nightmare, and the sleep terror occur preferentially during arousal from slow-wave sleep and are virtually never associated with the rapid-eye-movement [REM] dreaming state. Data reported here indicate that physiological differences from normal subjects, of a type predisposing the individual to a particular attack pattern, are present throughout the night. The episode, at least in the case of enuresis, appears to be simply a reinforcement of these differences to a clinically overt level. A number of features are common to all 4 sleep disorders. These were shown previously to be attributable to the arousal itself. New data obtained by means of evoked potential techniques suggest that these common symptoms of the confusional period that follows non-REM sleep are related to alterations of cerebral reactivity, at least of the visual system. Symptoms distinguishing the individual attack types (that is, micturition, prolonged confusional fugues, overt terror) appear to be based upon physiological changes present throughout sleep which are markedly accentuated during arousal from slow-wave sleep. These changes may in some way be related to diurnal psychic conflicts. To date, it has proved impossible to demonstrate potentially causal psychological activity, dreaming or other forms of mental activity, or even a psychological void in sleep just preceding the attacks. The attacks are best considered disorders of arousal. The slow-wave sleep arousal episode which sets the stage for these attacks is a normal cyclic event. Indeed it is the most intense reccurrent arousal that an individual regularly experiences. Detailed studies of those physiological changes that predispose individuals to certain types of attacks when they undergo intense arousal or stress may be informative; the reversal of these changes by psychological or pharmacological means, and more refined investigations of the physiological and psychological characteristics of the process of cyclic arousal from non-REM sleep.
