An editorial suggests that in clinical practice, assessment of sleep patterns may be of value in identifying higher risk individuals, though objective measures of sleep patterns are challenging and influenced by various situations and conditions, which would not be likely to be captured by questionnaires or conventional sleep screening during a single overnight sleep study.

It adds that patients needs to be made aware that sleeping a lot and having daytime naps may not always be that harmless.
