Alzheimer&Dementia:心脑轴的动脉钙化和随时间的认知表现研究

2024-12-06 MedSci原创 MedSci原创 发表于陕西省

动脉钙化与跨领域认知能力加速下降有关,尤其是靠近大脑的动脉。

痴呆症是一个全球性的健康问题,预计在未来几年将会加剧。虽然痴呆症的确切病因尚不清楚,越来越多的证据表明其涉及多种因素,包括动脉硬化(指血管硬化)。 更具体地说,心脑轴血管床的动脉硬化先前已被认为与痴呆和认知缺陷风险增加有关。据推测,这些缺陷是由于慢性灌注不足和小血管疾病造成的。

虽然之前的研究表明动脉硬化与认知功能障碍的风险增加有关,但仍有一些重要的知识差距有待解决。首先,大多数研究分别调查了动脉硬化在心脏和大脑认知障碍中的作用。因此,将心脑轴的动脉硬化整合到单一方法框架中的研究数量还很缺乏。其次,先前的研究已经横断面调查了动脉硬化和认知障碍之间的关系,使用差异分数作为结果。虽然这些研究为后续研究提供了宝贵的基础,但它们未能充分捕捉认知轨迹,并且无法对时间效应进行灵活的建模。

因此,本研究将通过评估心脑轴内主要动脉的动脉钙化(动脉硬化的标志)并研究其对纵向认知轨迹的影响来考虑这些知识差距。在以人群为基础的鹿特丹研究中,2368 名参与者接受了平扫 CT,以量化心脑轴 5 条主要动脉的动脉钙化(动脉硬化的标志)。扫描后,参与者接受了重复的认知测试。使用混合模型研究基线钙化与纵向认知测试表现之间的关联。

我们观察到所有认知领域和血管床的认知表现的基线差异。更具体地说,较高的冠状动脉钙化负担与基线时较低的 PPT 表现相关( β = -0.09 [95% 置信区间 (CI) = -0.14, -0.03])。较高的主动脉弓钙化负担始终与较低的基线g因子( β = -0.02 [95% CI = -0.04, -0.01])和所有认知子领域的基线表现较差相关(LDST: β = -0.10 [95% CI = -0.18,-0.02];斯特鲁普: β = 0.01 [95% CI = 0.00, 0.01];WFT: β = -0.11 [95% CI = -0.19,-0.04];WLT 延迟: β = -0.04 [95% CI = -0.08,-0.00];PPT: β = -0.09 [95% CI =-0.14,-0.03])。

钙化程度较高与各个领域的基线认知表现较差相关(例如,颅内颈动脉钙化每增加 10 个百分点,整体认知β :-0.01 [95% 置信区间 (CI):-0.03,-0.00])。在所有认知测试中,认知能力下降得更快,特别是颅内颈动脉 ( p ≤ 0.001)。在随访的前 5 年中,冠状动脉钙化增加 10 个百分点与g因子评分 ( p = 0.001) 以及 LDST 表现 ( p = 0.017) 的急剧下降相关。

综上,动脉钙化与跨领域认知能力加速下降有关,尤其是靠近大脑的动脉。这种效应可能归因于神经血管损伤之前的血流动力学变化。
