CHICAGO -- The sleep problems of older people are often not addressed by their primary care physicians, even though treatment of those sleep disorders could improve their physical and mental health and enhance their quality of life.

That's the finding of new research from the Feinberg School of Medicine at Northwestern University. When patients 60 years and older visited their primary care doctors, physicians did not note sleep problems in the patients' charts. This was significant because independent social workers, who interviewed those same patients after their doctors' visits, learned that 70 percent of them had at least one sleep complaint and 45 percent said they had "difficulty falling asleep, staying asleep, or being able to sleep."

Previous research has linked sleep disorders in the elderly to poorer mental and physical health and quality of life.

"A doctor may not think it's very important to ask the patient about sleep. We (the researchers) hypothesize that doctors think that sleep problems are a normal part of aging and there's not much they can do about it, " said Kathryn Reid, Ph.D., lead author on the study and research assistant professor of neurology at Northwestern's Feinberg School of Medicine. The study appeared in the American Journal of Geriatric Psychiatry.

Patients may also assume sleep problems are inevitable as they grow older and not mention them to their doctors, Reid said.

Some changes in sleep -- such as reduction in slow wave or deep sleep starting at about age 40 -- are natural as we age. But insomnia is not. One recent study showed that among older people with exceptionally good health, only about 1 percent had sleep difficulties.

"Now, a lot of studies show that not getting enough sleep can lower your metabolic function, be associated with cardiovascular problems, cancer and breast cancer in women and increase our mortality. Sleep deprivation also increases your sens
