Special Issue Information
Dear Colleagues,
The cognitive role of sleep involves contributing to memory consolidation and learning processes. Sleep deprivation leads to multiple cognitive deficits and decreased cognitive performance. Most evidently, inadequate sleep quality and quantity induce significant attention deficits that affect functionality throughout the day. Sleep dysregulation associates with elevated inflammation markers and cortisol levels that influence cognition and, particularly, proper memory function. Furthermore, sleep architecture undergoes significant age-related changes that further affect cognitive functioning. Cross-sectional studies indicate that insomnia-type symptoms and poor sleep quality are highly prevalent among the elderly and associate with increased odds for cognitive impairment, whereas other studies lean toward daytime sleepiness as a risk factor for cognitive decline. What is more, sleep disturbances have been linked to dementia and Mild Cognitive Impairment diagnosis and disease prognosis. Objectively assessed long sleep duration is particularly frequent among dementia patients and associates with reduced performance on high cognitive demand tasks, whereas this relationship may be driven by the genetic factors linked with Alzheimer’s disease. Taking under consideration the complex interplay between sleep processes, stress hormones, inflammation markers, and cognition, we welcome papers investigating the above factors in the current Special Issue.
