To systematically appraise the literature on the prevalence, types, and predictors of sleep-wake disturbances (SWD), and on the relationship between SWD, fatigue, depression, and quality of life in children and adolescents with traumatic brain injury (TBI).
MEDLINE, PubMed, PsychInfo, Web of Science, and EMBASE databases were searched, reference lists of retrieved articles were also searched for relevant articles, and study methods were evaluated for risk of bias.
Of the 620 articles assessed, 16 met inclusion criteria. Sleep-wake disturbances were common in childhood TBI. The most common types of SWD reported were insomnia and excessive daytime sleepiness, with mild TBI participants showing a trend toward more sleep maintenance insomnia, while sleep-onset insomnia was typical in those with moderate-severe TBI. Predictors of SWD reported in studies involving mild TBI participants included TBI severity, male sex, preexisting SWD, high body weight, and depression; while injury severity and internalizing problems were associated with SWD in moderate-severe TBI participants. Sleep-wake disturbances were also associated with fatigue and poor quality of life following TBI.
Sleep-wake disturbances are highly prevalent in childhood TBI, regardless of injury severity. Routine assessments of SWD in survivors of childhood TBI are recommended.
