Sleep and health are inextricably linked. A new study by scientists from the Brigham and Women's Clinic examined the relationship between disorders and deficits of sleep in the elderly and the risk of dementia and death.

It found that the risk of dementia was twice as high among participants who reported sleeping less than five hours a night compared to those who slept seven to eight hours.

The team also found an association between sleep disturbance and lack of sleep with the overall risk of death.

"Our findings shed light on the link between sleep deprivation and the risk of dementia and support the importance of efforts to help older adults get enough sleep," said lead author Dr. Rebecca Robbins of the Division of Sleep and Circadian Disorders.

Overall, the researchers found a close relationship between several variable disturbances and sleep deficits and dementia that occurs over time.

Falling asleep half an hour or longer was associated with a 45 percent increased risk of dementia. Regular difficulty staying alert, daytime sleepiness, reporting poor sleep quality, and sleeping less than five hours were also associated with an increased risk of death.
