The relationship between cognitive function and non-prescribed therapy use in older adults.
OBJECTIVE
To examine the association of cognitive function with use of non-prescribed therapies for managing acute and chronic conditions, and to determine whether use of non-prescribed therapies changes over time in relation to baseline cognitive function.


METHODS
200 community-dwelling adults aged 65 and older were recruited from three counties in south central North Carolina. Repeated measures of daily symptoms and treatment were collected on three consecutive days at intervals of at least one month. The Mini-Mental State Examination, the primary cognitive measure, was collected as part of the baseline survey. Data were collected on the daily use of common non-prescribed therapies (use of prayer, ignore symptoms, over-the-counter remedies, food and beverage therapies, home remedies, and vitamin, herb, or supplements) on each of the three days of the follow-up interviews for up to six consecutive months.


RESULTS
Older adults with poorer cognitive function were more likely to pray and ignore symptoms on days that they experienced acute symptoms. Poorer cognitive function was associated with increased use of home remedies for treating symptoms related to existing chronic conditions.


CONCLUSIONS
Cognitive function may play a role in why older patients use some non-prescribed therapies in response to acute and chronic conditions.
