New research has revealed that there may be a link between obesity and the loss of brain tissue.

According to researchers from the Sahlgrenska University Hospital, in Sweden, carrying extra weight and conditions such as diabetes can be a key factor in tissue loss in women, which then leads on to the development of dementia.

Lead researcher, Deborah Gustafson, told BBC News Online: "Obesity may also increase the secretion of the hormone cortisol, which could lead to atrophy.

"If overweight and obesity contribute not only to diseases of middle age, but also to degenerative diseases of later life, the health ramifications of excess body fat will stress healthcare systems for many years to come," she added.

As part of the research nearly 300 women aged between 46 and 60 were studied over a period of 24 years.

Based on tests every six years, results showed the higher a woman's Body Mass Index (BMI) the more likely their chances of developing brain tissue loss.

The researchers argue the findings provide even further evidence for the need to address the issue of obesity and to promote healthy eating.
