A runny nose, fallen arches and dentures aren’t risk factors typically associated with brain health. But new research suggests that small health problems can add up, and the combined effect can increase a person’s risk for dementia. The findings, published on Wednesday in the journal Neurology, are based on an analysis of 7,239 people age 65 and older who took part in the Canadian Study of Health and Aging between 1992 and 2002.
