概括

眼际质细胞内状层 (GC-IPL) 的不对称性可能预测老年人的认知脆弱性. 这种视网膜不对称性与认知衰退和记忆障碍有关,可能作为一种新的生物标志物.

科学领域:

眼科医生眼科眼科
老年学是一门学科.
神经科学是一个神经科学.

背景情况:

视网膜神经纤维层 (RNFL) 和质细胞内状层 (GC-IPL) 与认知障碍有关.
视网膜不对称性和认知虚弱 (CF) 之间的关系尚未得到充分理解.

研究的目的:

调查整眼视网膜不对称与社区老年人认知脆弱的发展之间的关联.
探索RNFL或GC-IPL不对称性是否会随着时间的推移预测认知脆弱性的变化.

主要方法:

从2015年到2022年,对222名老年人进行了随访,每两年进行一次认知和脆弱性评估.
视网膜不对称性被定义为GC-IPL和RNFL厚度的绝对整眼差异.
用了通用线性混合模型来分析CF的风险随着时间的推移,与手握强度不对称的相互作用分析.

主要成果:

较大的基线GC-IPL不对称性与CF随时间的推移恶化有关 (aOR=1.06).
手握强度不对称性显著改变了GC-IPL不对称性和CF之间的关联 (p=0.02).
GC-IPL不对称性与认知障碍相关,但与身体虚弱无关;RNFL不对称性与CF没有显著的关联.

结论:

眼间GC-IPL不对称可能成为老年人认知虚弱的新型结构生物标志物.
这些发现突显了视网膜成像在早期检测认知衰退和虚弱方面的潜力.

关键词:

Cognitive Development During Adulthood

Cognitive Development During Adulthood

Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...
