Parents of children with Neurodevelopmental Disabilities (NDDs) are at risk of sleep loss. No comprehensive systematic reviews examining parental sleep outcomes in caregivers of children with NDDs exist. A systematic search was conducted between June and August 2016 examining sleep quantity, quality, sleepiness, and fatigue outcomes of caregivers of children with NDDs. Of 7,534 citations retrieved, 33 met eligibility criteria. Most studies (n = 27) were cross-sectional, included a range of NDDs and were of “poor” (n = 14) or “fair” (n = 17) quality.
