Enuretic sleep: deep, disturbed or just wet?

Enuretic children sleep "deeply" in the sense that they are difficult to arouse from sleep, but not in the sense that their sleep is necessarily polysomnographically different from other children. The enuretic children's arousal difficulties may be due to a disturbance at the brainstem level and/or to frequent arousal stimuli from the bladder. It may be hypothesised that the sleep disturbance of enuretic children may lead not only to the wetting of the sheets but to disturbances of daytime psychological functioning as well.
