Negative Consequences of Sleep Deprivation Experienced by Informal Caregivers of People With Dementia on Caregivers and Care Recipients: A Scoping Review

AimsThis study aimed to summarise the results of research concerning the impact of sleep deprivation among informal caregivers of People with Dementia (PwD) and their care recipients. MethodsThis was a scoping review and followed the PRISMA Scoping Review guideline. Seven electronic databases were searched, and all studies that provided information regarding any outcomes related to sleep deprivation among informal caregivers of PwD published before July 2022 were included. ResultsSixty studies were identified. Mental and physical effects caused by caregivers' sleep deprivation have been observed. Biomarkers of stress, cognitive functions, immune system functions, and mental status, including burden, depression, and distress, were most frequently mentioned in caregivers with regards to sleep deprivation. As for PwD, mental health indicators like depression and behavioural change were related to sleep deprivation of caregivers. The relationship between caregivers and PwD, as well as the family's financial situation change were also identified. ConclusionSleep deprivation in caregivers of PwD harms both parties, underscoring the need for adequate caregiver rest and interventions targeting sleep issues. Future research should explore more care factors and standardise sleep deprivation metrics, improving support for caregivers and patient care.
