(WebMD) Being overweight or obese in middle age shrinks your brain, aging it by as much as 10 years, according to a new study.
People who are overweight or obese during middle age have brains with much less white matter than people of the same age at a healthy weight, says study researcher Lisa Ronan, PhD, at the University of Cambridge in the U.K…
''The white matter of the brain is thought to be the first to go with dementia," says Mike Henne, PhD, a spokesman for the American Federation for Aging Research. Loss of white matter is generally associated with “foggy-mindedness," he says.
White matter declines with age, usually beginning in the late 30s, so holding on to as much as you can is desirable.
"If you lose white matter, the [brain's] neurons are not as capable of communicating with each other," says Henne, assistant professor of cell biology at the University of Texas Southwestern Medical Center.[Click the title, above, to post a comment.]
