Nonrestorative sleep: Symptom or unique diagnostic entity
Sleep Medicine, 06/29/2012
Wilkinson K et al. – Nonrestorative sleep (NRS) refers to the subjective experience of sleep as insufficiently refreshing, often despite the appearance of normal sleep according to traditionally assessed objective parameters. This has led researchers to pursue alternative physiological markers of nonrestorative or unrefreshing sleep, though much of this research remains controversial and inconclusive.
