In adults aged between 50 and 64 years of age, short sleep (less than 6hrs per night) and long sleep (more than 8hrs per night) were associated with lower brain function scores, while in older adults (65-89 years), lower brain function scores were only observed in long sleepers.
Dr Michelle A Miller said that 6-8 hours of sleep per night is particularly important in younger adults for optimum brain function as it helps physical health, lowers the risk of developing obesity, hypertension, diabetes, heart disease and stroke.
Dr Miller concluded that if poor sleep was causative of future cognitive decline, non-pharmacological improvements in sleep may provide an alternative low-cost and more accessible Public Health intervention, to delay or slow the rate of cognitive decline.
The study is published in PLOS ONE. (ANI)
