Non-restorative sleep is the strongest, independent predictor of widespread pain onset among adults over the age of 50, according to a new study in Arthritis & Rheumatology. Researchers in the United Kingdom found anxiety, memory impairment and poor physical health among older adults may also increase the risk of developing widespread pain.

Chronic pain affects more than 100 million Americans at a cost topping $600 billion annually, according to the Alliance for Aging Research. Musculoskeletal pain is more prevalent as people age, with up to 80 percent of people 65 years of age and older experiencing daily pain. Widespread pain that affects multiple areas of the body – the hallmark feature of fibromyalgia – affects 15 percent of women and 10 percent of men over age 50 according to previous studies. While there is no cure for chronic pain, several studies suggest that exercise and Vitamin D supplements may be beneficial. Continue reading

How much and how well older adults sleep may be associated with Alzheimer’s disease, according to a study published in JAMA Neurology this week. Researchers from The Johns Hopkins Bloomberg School of Public Health found that buildup of ß-Amyloid plaques — one of the hallmarks of the disease — was greater in people who reported sleep disturbances and who slept for fewer hours than those who got at least seven hours of Z’s with good sleep quality.

Fluctuations in ß-Amyloid levels may be regulated by sleep-wake patterns according to the report’s authors. Investigators looked at data from 70 adults (average age 76 years) in the Baltimore Longitudinal Study of Aging. Plaque buildup was measured by imaging of the brain.

According to the National Institute on Aging, as many as 5.1 million Americans may have the disease. First symptoms usually appear after age 60, but it’s likely that damage to the brain starts a decade or more before problems are evident. Previous studies have linked disturbed sleep to cognitive impairment in older people.
