Background/aim Patients frequently report sleep disruptions or insomnia during their hospital stay, particularly after a traumatic brain injury ( TBI ). The consequences of these sleep disturbances on everyday activities are not well documented and are therefore not considered in the evaluation of independence in activities of daily living ( ADL s). The goal of this narrative review is to explore the consequences of poor sleep quality on cognition and ADL s in the acute and subacute stages of a moderate and severe TBI , when patients are in acute care or inpatient rehabilitation. Methods We will present an overview of normal sleep and its role in cognitive functioning, and then present the findings of studies that have investigated sleep characteristics in hospital settings and the consequences of sleep disturbances on ADL s. Results During hospitalisation, TBI patients present severe sleep disturbances such as insomnia and sleep fragmentation, which are probably influenced by both the medical condition and the hospital or rehabilitation environment. Sleep disruption is associated with several cognitive deficits, including attention, memory and executive function impairments. Poor quality and/or insufficient quantity of sleep in acute TBI probably affect general functioning and ADL s calling for these cognitive functions. Conclusions and Significance The cognitive impairments present following TBI are probably exacerbated by poor sleep quality and sleep deprivation during hospitalisation, which in turn impact ADL s among this population. Health‐care personnel should further consider sleep disturbances among people with TBI and a sleep protocol should be established.
