Sleep studies based on electroencephalogram energy analysis.
Current sleep studies use the manual polysomnographic technique or frequency analysis when investigating the mechanisms behind the incomplete transition from sleep to consciousness. Ten control subjects and 11 primary monosymptomatic enuretics were studied in a sleep laboratory for three consecutive nights (23.00-07.00 h). The results showed no significant differences in sleeping pattern between enuretics and controls. Enuretics spent more time in stage 3 sleep than controls on recovery nights, indicating greater depth of sleep. No differences in sleep architecture were noted between the groups on baseline nights, although enuretics showed a shorter total sleep period than controls on the recovery night. Increased delta waves exhibited in the enuretic group are indicative of a greater depth of sleep. Moreover, electroencephalogram readings showed an impaired arousal in enuretics, which suggests that sleep may be a part of the pathology of enuresis.
