Body shape affects memory

A woman's body shape may play a role in how good her memory is, according to a new study.

The more an older woman weighs, the worse her memory, according to research released this week from Northwestern Medicine at Northwestern University in Evanston, Illinois.

The effect is more pronounced in women who carry excess weight around their hips, known as pear shapes, than women who carry it around their waists, called apple shapes.

The reason pear-shaped women experienced more memory and brain function deterioration than apple-shaped women is likely related to the type of fat deposited around the hips versus the waist.
