背景:注意力是一种必不可少的认知能力,在其他认知过程中是必需的。只有少数研究关注认知能力下降的老年人的特定注意力功能下降。没有研究探索健康控制(HC)与主观认知下降(SCD)的老年人之间的主动和反应控制模式的差异。
目标:当前的工作调查了警报是否有所下降,定向,和SCD中的执行控制。特别是,本研究进一步探讨了SCD中主动控制和反应控制的损害.
方法:我们招募了25例HC和26例SCD。所有参与者首先完成一组神经心理学评估。然后,他们完成了注意力网络测试,以测量警报,定向,和执行控制,用于测量主动和被动控制模式的列表范围和特定项目比例一致性效果任务,分别。
结果:在警报方面没有发现差异,定向,和由SCD和HC之间测量的执行控制。结果还表明SCD和HC之间的反应性控制没有差异。然而,与HC相比,SCD的老年人在主动控制中表现较差.
结论:患有SCD的老年人在主动控制方面表现出损害。当前的发现有助于我们更好地理解除记忆以外的认知领域的客观下降,并阐明AD的早期评估和预防。
Attention is an essential cognitive ability that is necessary in other cognitive processes. Only few studies have focused on decline in specific functions of attention in older adults with cognitive decline. No research explores the difference in the proactive and reactive mode of control between the healthy control (HC) and older adults with subjective cognitive decline (SCD).
The current work investigated whether there was any decline in alerting, orienting, and executive control in SCD. Particularly, the present study further explored the impairment of the proactive and reactive control in SCD.
We recruited 25 HC and 26 SCD. All participants first finished a set of neuropsychological assessments. They then completed an Attention Network Test for measuring the alerting, orienting, and executive control, the List-wide and the Item-specific Proportion Congruency Effect task for measuring the proactive and reactive mode of control, respectively.
No difference was found in alerting, orienting, and executive control measured by the ANT between SCD and HC. The results also indicated no difference in the reactive control between SCD and HC. However, older adults with SCD performed worse in the proactive control as compared to HC.
Older adults with SCD showed an impairment in the proactive control. The current findings help us better understand objective decline in cognitive domains other than memory and shed light on early assessment and prevention of AD.
