The relationship between low blood pressure and cognitive function among younger individuals is not fully understood. While a number of studies have examined hypertensive and hypotensive individuals, particularly in older populations, little attention has been devoted to healthy, young populations. We tested 105 healthy young individuals whose blood pressure levels naturally fell in the below normal-to-normal range. Our primary finding was a positive relation between blood pressure and cognition, as measured by two visuospatial attention tasks. This relation appears to be specific to visuospatial skills, as no relationship was observed between recognition memory and blood pressure. We discuss possible explanations for this positive relationship, such as structural neural mechanisms, and how they apply to the overall blood pressure-cognition relationship.
年轻人中低血压与认知功能之间的关系尚未完全明确。尽管已有多项研究对高血压和低血压个体进行了考察,尤其是在老年人群中,但针对健康的年轻人群的研究却很少。我们对105名血压水平自然处于低于正常至正常范围的健康年轻人进行了测试。我们的主要发现是,通过两项视觉空间注意力任务测量,血压与认知之间呈正相关。这种关系似乎特定于视觉空间技能,因为在识别记忆与血压之间未观察到相关性。我们讨论了这种正相关关系的可能解释,比如神经结构机制,以及它们如何适用于整体的血压-认知关系。
