Abstract

<p>Severe cognitive impairment is an established risk factor of falls in the older adults. However, it is unclear whether mild cognitive impairment has an impact for falls and which subtypes of mild cognitive impairment have the greatest association with falls. The purpose of the study was to evaluate the epidemiological evidence linking cognitive impairment and falls. A total of 7712 older adults aged 65 years and older（average age: 73.2 years）participated in the study. Each participant underwent detailed cognitive testing to assess MCI. Screening for MCI included a standardized personal interview, the Mini-Mental State Examination, and the National Center for Geriatrics and Gerontology-Functional Assessment Tool（NCGG-FAT）, which included the tests of memory, attention and executive function, processing speed, and visuospatial skill. The fall rate, single fall during previous year, of cognitively normal, amnestic MCI single domain, amnestic MCI multiple domain, nonamnestic MCI single domain, and non-amnestic MCI multiple domain was 16.7%, 20.1%, 22.6%, 17.5%, and 19.9%, respectively（χ 2 = 11.95，p = 0.018）. We found significant relationships between single fall and amnestic MCI multiple domain, the odds ratio was 1.40（95% confidence interval 1.06 to 1.84, p = 0.017）. Future investigation is necessary to determine whether this population is at increased risk for incidence of fall-related disability.</p>
