Emerging research suggests that a relationship exists between the cognitive aspects of anxiety (e.g. worry) and cognitive decline in older adults. The current study examined the association between anxiety, depressive, and worry symptoms on cognitive performance. Participants were 156 older adults enrolled in the Nathan Kline Institute-Rockland Sample Study (NKI-RS). Hierarchical linear regression analysis was used to determine the unique associations of anxiety, depressive, and worry symptoms on cognitive performance as measured by the Penn Computerized Neurocognitive Battery (Penn CNB), the Delis-Kaplan Executive Function System (D-KEFS), and the Rey Auditory Verbal Learning Test (RAVLT). Worry symptoms were a significant predictor of Penn CNB social cognition, complex cognition, executive function, and episodic memory performance as well as RAVLT immediate and short-delay recall, but not of D-KEFS performance or RAVLT long-delay recall. In contrast, anxiety and depressive symptoms had few unique associations with cognitive performance. Given that worry symptoms have a negative impact on many aspects of neurocognitive performance, they may have utility in predicting and preventing cognitive decline in older adults.
新兴研究表明，焦虑的认知方面（例如担忧）与老年人的认知能力下降之间存在关联。本研究探讨了焦虑、抑郁和担忧症状与认知表现之间的关系。参与者为参加内森·克莱恩研究所-罗克兰样本研究（NKI-RS）的 156 名老年人。使用分层线性回归分析来确定焦虑、抑郁和担忧症状对认知表现的独特关联，认知表现由宾夕法尼亚计算机化神经认知电池（Penn CNB）、德里斯科尔-卡普兰执行功能系统（D-KEFS）和雷氏听觉言语学习测试（RAVLT）测量。担忧症状是 Penn CNB 社会认知、复杂认知、执行功能和情景记忆表现以及 RAVLT 即时和短延迟回忆的重要预测指标，但不是 D-KEFS 表现或 RAVLT 长延迟回忆的预测指标。相比之下，焦虑和抑郁症状与认知表现的关联较少。鉴于担忧症状对神经认知表现的许多方面都有负面影响，它们可能有助于预测和预防老年人的认知能力下降。
