Being underweight can cause dementia, according to researchers from the Boston University School of Medicine.. Study results published in Journal of Alzheimer's Disease.

The researchers found that with a low body mass index - the ratio of a person's weight to his height - at the age of 50-60 years, a person will be less likely to avoid dementia.

Researchers analyzed the Framingham Heart Study to find new risk factors for dementia.

In particular, scientists drew attention to demographic data, as well as information about the lifestyle of people in 1979-1983, and found out which of them were diagnosed with dementia..

In earlier studies, experts say, the main factor leading to dementia was called age.. However, as the observation showed, underweight people aged 50-60 years had dementia more often than their peers with normal weight..

Among other negative factors contributing to brain aging, scientists also identified lack of sleep and widowhood..
