If you’re looking for another reason to get more active and shed some pounds, this should do the trick. A study published in the journal Neurology links obesity with dementia later in life. Approximately 6,400 participants averaging 50 years of age were followed for 10 years, during which they were tested three times to assess reasoning, short-term memory and verbal fluency. The study included people considered normal weight, overweight and obese. The results showed that people who are obese, have high blood pressure and have other metabolic risk factors see a faster decline in cognitive skills than people of normal weight.
