Memory Problem in Older Women Lead to Restless Nights

For the study, 2,474 women with an average age of 69 and no signs of memory problems underwent cognitive tests over 15 years. Sleep problems were measured at the end of the study.
The study found the nearly 25 percent of women who experienced cognitive decline were twice as likely as women without memory problems to experience sleep disturbances.
For women who declined on either cognitive test, they were nearly twice as likely to have difficulty staying asleep and one-and-half times as likely to have problems falling asleep and being awake for more than 90 minutes during their sleep cycle, said study author Kristine Yaffe, MD, with the University of California, San Francisco, and member of the American Academy of Neurology.
Women who declined on one of the tests were also nearly twice as likely to nap more than two hours a day.The study found cognitive decline was not associated with total sleep time.
Perhaps the most likely reason why memory loss may increase the risk of sleep disturbances is that they share a common underlying cause, such as brain changes seen with Alzheimers disease or other dementias that could increase risk of both memory loss and sleep problems, said Yaffe.
