We know that obesity is a risk factor for Alzheimer's disease, dementia and stroke, so if you want to keep your wits about you as you age, you might want to pare some pounds now if you're overweight or obese. A study at Kent State University found that overweight patients who had gastric bypass surgery scored much better on tests of memory and cognitive function after shedding about 50 pounds in the months following the operations. The investigation included 150 patients all of whom were tested initially to assess their mental abilities; then 109 participants underwent the surgery. Cognitive tests 12 weeks later showed that patients in this group scored much better than they had before their weight loss. A decline in mental function was seen among the 41 patients who didn't have surgery (the researchers aren't sure why). The investigators suggested that the improvements after weight loss might be due in part to lower blood pressure. The same team will next study whether comparable improvements occur as a result of losing weight via diet and exercise.
