Weight changes may indicate dementia

How does our weight affect the risk of dementia?

Researchers from South Korea have now found that significantly increasing or decreasing weight in the elderly is associated with increased risk of developing dementia.

A recent study by the Kyungpook National University has shown that there is a correlation between changes in body mass index in late life and early dementia. The results of the research were published in the journal "BMJ Open" in English.

Data from more than 67,000 elderly people were estimated

The results show how important it is to maintain a healthy lifestyle in old age. The study analyzed the data of more than 67,000 people aged between 60 and 79 years. Body mass index (BMI) was measured in 2002, 2003 and again between 2004 and 2005, while dementia was monitored for an average of five years between 2008 and 2013.

Fast BMI changes point to dementia

Men and women who experienced a rapid weight change, defined as increasing or decreasing BMI by ten percent over a two-year period, had about 20 percent higher risk of developing dementia than participants whose weight remained stable.

Increase in fatty mass contributes to dementia?

BMI at the start of the study was not associated with the frequency of dementia in both sexes, except for men with low body weight. Researchers believe that weight gain and related weight gain may affect the development of dementia. They added that weight loss could also be an early symptom of the disease. Weight gain and weight loss may be significant risk factors for dementia, the authors of the study explained.

These factors increase the risk of dementia

Current research has shown that severe weight gain, uncontrolled diabetes, smoking, and weaker liver function of lifestyle reduce the development of dementia. Findings indicate that continuous weight control, disease management, and healthy lifestyle maintenance will help prevent dementia later in life. (As)
