A recent study at the Mayo Clinic in Rochester, MN, indicates that women may actually start losing weight as much as a decade before the onset of dementia. They found that women started losing weight at a more accelerated pace 10 years before they developed dementia. The study did not show the same findings in men. The reasons for weight loss as a marker for dementia is not clear. Some researchers believe that early weight loss results as a result of problems in an area of the brain called the hypothalamic system.

Other studies have shown that weight loss is associated with development of dementia and with nursing home placement, but the timing and rate of the weight loss in relationship to the first signs of dementia are unknown, the authors noted.

They looked at rates of weight change in volunteers men, women , who were cognitively healthy at baseline. The volunteers were controls in a longitudinal study of memory and aging. Participants were weighed at study outset and at annual visits. The investigators created piecewise linear regression and random effects models to test longitudinal rates of weight change between the demented and non-demented groups.

An NHS Health Check is a free check-up of your overall health for people aged 40 to 74 who do not have heart disease, diabetes or kidney disease, and have not had a stroke. It's offered every 5 years. The NHS Health Check can help find early signs and tell you if you're at higher risk of certain health problems that can also increase your risk of dementia.

These include:. If you're over age 65, you'll be told the signs and symptoms of dementia to look out for. You'll also be given advice on how to lower your risk of dementia.
