Improving and maintaining health factors not traditionally associated with dementia, such as denture fit, vision and hearing, may lower a person’s risk for developing dementia. Kenneth Rockwood, from Dalhousie University (Canada), and colleagues studied 7,239 people who were free of dementia ages 65 and older, enrolled in the Canadian Study of Health and Aging. After five years and again after 10 years, they were evaluated for Alzheimer’s disease and all types of dementia. Participants were asked questions about 19 health problems not previously reported to predict dementia. Problems included arthritis, trouble hearing or seeing, denture fit, chest or skin problems, stomach or bladder troubles, sinus issues, broken bones and feet or ankle conditions, among others. After 10 years, 2,915 of the participants had died, 883 were cognitively healthy, 416 had Alzheimer’s disease, 191 had other types of dementia, 677 had cognitive problems but no dementia, and the cognitive status of 1,023 people was not clear. The study found that each health problem increased a person’s odds of developing dementia by 3.2%, as compared to people without such health problems. Older adults without health problems at baseline had an 18% chance to become demented in 10 years, while such risk increased to 30% and 40% in those who had 8 and 12 health problems, respectively. The researchers conclude that: “General health may be an important confounder to consider in dementia risk factor evaluation. If a diverse range of deficits is associated with dementia, then improving general health might reduce dementia risk.”
