In paradoxical insomnia, one or more of the following criteria apply:

  • The patient reports a chronic pattern of little or no sleep most nights, with rare nights during which relatively normal amounts of sleep are obtained

  • Sleep log data from one or more weeks of monitoring often show no sleep at all for several nights each week; typically, daytime naps are absent following such nights

  • There is typically a mismatch between objective findings from polysomnography or actigraphy and subjective sleep estimates from a self-reported sleep diary
