Obesity harms memory
Obesity may impair memory, at least for women after menopause. A study published July 14 in the Journal of the American Geriatric Society looked at memory test scores for 8,745 women ages 65 to 79. The researchers found a 1-point increase in an woman’s body mass index (BMI) was associated with a 1-point decrease on a 100 point memory test.
Hormones released by fat could impair memory, the researchers said. These hormones can cause inflammation, which may affect cognition.
