Possible weight link to memory

We know being overweight can be tough on the body. Now researchers at Northwestern University Medical School have found it's also bad for your brain.

Researchers gave nearly 9,000 women a memory test and measured their body mass index. The results: overall, a women's memory decreased as her BMI increased. And her memory scores were even lower when her waist-to-hip ratio was smaller.

Researchers suspect women with a pear shape are more likely to have a type of fat around the hips that release hormones causing inflammation. That inflammation could then affect cognition and blood flow to the brain.
