Overeating could double the risk of cognitive impairment, or a decline in mental abilities, according to a study from the Mayo Clinic.
A study performed by the Mayo Clinic suggests that overeating can more than double the risk of mild cognitive impairment (MCI) in the elderly. While the study is only a preliminary one, it suggests that cutting calories may be a simple way to prevent or slow memory loss as people age.
Mild cognitive impairment is a decline in mental abilities, chiefly memory, that's noticeable but not severe enough to affect the performance of day to day activities. It's sometimes described as an intermediate stage between the expected cognitive decline of normal aging and the more pronounced decline of dementia. People with MCI are at increased risk of developing dementia later on in life.
The study was of 1,233 individuals aged 70 to 89 who were taking part in a larger study, the Mayo Clinic Study of Aging. These individuals reported their daily calorie consumption and were then interviewed within one year and tested for MCI. About 13 percent had MCI (163 people); the other 1,070 did not.
