More research is needed to examine the relationship between specific neuropsychological functions and observation-based daily activity tests in patients with Alzheimer's disease (AD). Fifty-six patients with AD were administered tests of attention and processing speed and an observation-based activities-of-daily-living (ADL) task. Complex short-term attention capacity best predicted real-world task performance, accounting for several domains of ADL functioning. These results suggest that complex attention requiring working-memory systems, but not simple attention or processing speed, account for moderate portions of variability in daily task performance. These results may aid in understanding the attentional processes required for performing daily activities and can be useful to health care professionals in treatment planning.
需要更多研究来考察阿尔茨海默病（AD）患者特定神经心理功能与基于观察的日常活动测试之间的关系。对56名AD患者进行了注意力和处理速度测试以及一项基于观察的日常生活活动（ADL）任务。复杂的短期注意力容量最能预测现实世界中的任务表现，解释了ADL功能的几个领域。这些结果表明，需要工作记忆系统的复杂注意力，而非简单注意力或处理速度，在日常任务表现的变异性中占了相当比例。这些结果可能有助于理解进行日常活动所需的注意力过程，对医疗保健专业人员进行治疗规划可能有用。
