Obesity harms 'later brain skill'


Being overweight in later life puts you at higher risk of brain decline, Korean research suggests.

A study of 250 people aged between 60 and 70 found those with a high body mass index (BMI) and big waists scored more poorly in cognitive tests.

The Alzheimer's Society said the research, in the journal Age and Ageing, added to evidence that excess body fat can affect brain function.

Lifestyle changes can help make a difference, it said.

The study looked at the relationship between fat levels and cognitive performance in adults aged 60 or over.

The participants underwent BMI - a calculation based on a ratio of weight to height - and waist circumference measurements, a scan of fat stored in the abdomen and a mental test.
