Because it enables necessary cognitive function restoration and rest, sleep is an essential component of maintaining healthy brain tissue. In recent years, there has been a growing interest in understanding the complicated relationship between sleep and cognitive function, as well as the possible repercussions of sleep disorders on brain health. This interest has been fueled in part by the realisation that sleep deprivation can have negative effects on cognitive performance. This review paper is to investigate the significance of sleep for cognitive performance, with a particular emphasis on the function of sleep in maintaining healthy brain function, the detrimental effects of sleep disorders such as obstructive sleep apnea, and the ameliorative effects of regular physical activity on both sleep and cognitive ability. The paper also covers the use of neuropsychological testing to detect cognitive deficits associated with sleep disorders, as well as the potential link between poor sleep quality and the development of Alzheimer's disease. In addition, the authors consider the possibility of a link between poor sleep quality and the development of Parkinson's disease. In general, this study highlights the important role that sleep plays in maintaining a healthy brain as well as the requirement for additional research to better understand the intricate relationships that exist between sleep and cognitive function. This article demonstrates the value of prioritising sleep as an essential component of one's overall health and well-being by underlining the significance of enough rest for achieving one's full potential in terms of cognitive performance.
