Cognitive impairment and fear of falling are risk factors for falls in older adults. Recurrent falls are more prevalent in older adults with cognitive impairment. We examined the number of previous falls, self-reported fear of falling, and the Falls Efficacy Scale-International (FES-I) in 104 older adults [26 with mild Alzheimer's disease (AD), 42 with mild cognitive impairment (MCI) and 36 cognitively healthy]. Older adults with AD and MCI had a higher number of falls (1.1 ± 1.2 and 1.5 ± 1.5, respectively) compared to the control group (0.3 ± 0.5, P < .001). Older adults with MCI more often reported fear of falling (74%) than patients with AD (31%) (P ≤ .002) and scored higher on the FES-I (29.7 and 23.8, respectively, P ≤ .01). The prevalence of falls in older adults with MCI and AD is higher than in subjects cognitively healthy. Older adults with MCI and AD differ in terms of reported fear of falling and falls self-efficacy.
认知障碍和害怕跌倒都是老年人跌倒的风险因素。反复跌倒在患有认知障碍的老年人中更为普遍。我们对104名老年人（26名患有轻度阿尔茨海默病，42名患有轻度认知障碍，36名认知健康）的既往跌倒次数、自我报告的害怕跌倒情况以及国际跌倒效能量表（FES-I）进行了研究。与对照组（0.3±0.5，P<.001）相比，患有阿尔茨海默病和轻度认知障碍的老年人跌倒次数更多（分别为1.1±1.2和1.5±1.5）。与患有阿尔茨海默病的患者（31%）相比，患有轻度认知障碍的老年人更常报告害怕跌倒（74%）（P≤.002），且在FES-I上得分更高（分别为29.7和23.8，P≤.01）。患有轻度认知障碍和阿尔茨海默病的老年人跌倒的发生率高于认知健康的受试者。患有轻度认知障碍和阿尔茨海默病的老年人在报告的害怕跌倒情况和跌倒自我效能方面存在差异。
