Hughes AJ, et al. - Researchers performed a systematic review to summarize recent research on the association between sleep disturbance and cognitive dysfunction in MS. In addition, they discussed assessment methodology, domain-specific associations between sleep disturbance and cognitive dysfunction, and implications for future research and treatment. As per findings, for predicting future cognitive decline in MS, sleep disturbance could provide help. Results thereby underscore the significance of integrating sleep assessment into routine MS care. For improving cognitive dysfunction in MS, interventions aimed treating sleep disturbance could offer promise.
