Women with broader waists, or those classed as "apple-shaped", are much more likely to be hit by dementia in later life, according to a new study from Sweden.
Senior lecturer at the Sahlgrenska Academy at Gothenburg University Deborah Gustafson published the study's findings in science journal Neurology, noting that while being overweight increases the risk of heart attack and stroke, people living beyond 70 are much more susceptible to the disease.
Researchers used statistics which started at the end of the 1960s, with nearly 1,500 women between the ages of 38 and 60 undergoing a number of examinations and responding to questions about their health and lifestyle.
Dr Gustafson continued: "Other studies have shown that a high BMI is also linked to dementia, but this was not the case in our findings.
"This may be because obesity and overweight [issues] were relatively unusual among the women who took part in the prospective population study."
Earlier this month, and in response to the government's care guidelines in the Queen's speech, Neil Hunt of the Alzheimer's Society called for dementia to be prioritised.
