Objective:The current cross-sectional study examined cognition and performance-based functional abilities in a continuing care senior housing community (CCSHC) that is comparable to other CCSHCs in the US with respect to residents’ demographic characteristics.Method:Participants were 110 older adult residents of the independent living unit. We assessed sociodemographics, mental health, neurocognitive functioning, and functional capacity.Results:Compared to normative samples, participants performed at or above expectations in terms of premorbid functioning, attention span and working memory, processing speed, timed set-shifting, inhibitory control, and confrontation naming. They performed below expectation in verbal fluency and verbal and visual learning and memory, with impairment rates [31.4% (>1 SD below the mean) and 18.49% (>1.5 SD below the mean)] well above the general population (16% and 7%, respectively). Within the cognitive test battery, two tests of delayed memory were most predictive of a global deficit score. Most cognitive test scores correlated with performance-based functional capacity.Conclusions:Overall, results suggest that a subset of older adults in the independent living sector of CCSHCs are cognitively and functionally impaired and are at risk for future dementia. Results also argue for the inclusion of memory tests in abbreviated screening batteries in this population. We suggest that CCSHCs implement regular cognitive screening procedures to identify and triage those older adults who could benefit from interventions and, potentially, a transition to a higher level of care.

居住在持续护理老年住房社区的老年人认知和功能障碍的比率


目的：当前的横断面研究检查了持续护理老年住房社区 (CCSHC) 中基于认知和表现的功能能力，该社区在居民人口特征方面与美国其他 CCSHC 相当。方法：参与者为 110 名老年人独立居住单位的居民。我们评估了社会人口统计学、心理健康、神经认知功能和功能能力。结果：与标准样本相比，参与者在病前功能、注意力广度和工作记忆、处理速度、定时设定转换、抑制控制、和对抗命名。他们在言语流畅性以及言语和视觉学习和记忆方面的表现低于预期，损伤率 [31.4%（>1 SD 低于平均值）和 18.49%（>1.5 SD 低于平均值）] 远高于一般人群（16分别为 % 和 7%）。在认知测试组中，两项延迟记忆测试最能预测整体缺陷分数。大多数认知测试分数与基于表现的功能能力相关。结论：总体而言，结果表明 CCSHC 独立生活部门的一部分老年人存在认知和功能受损，并且有未来患痴呆症的风险。研究结果还支持在该人群中将记忆力测试纳入简化筛查组中。我们建议 CCSHC 实施定期认知筛查程序，以识别和分类那些可以从干预措施中受益的老年人，并有可能从向更高水平的护理过渡中受益。
