The effects of chronic low and high blood pressure on memory are unclear due to divergent results, originating in part due to participant misclassifications. The aim of this study was to compare source memory and working memory performance in individuals diagnosed with hypotension or hypertension with the performance of normotensive participants. Hypertensive and hypotensive individuals were receiving medical treatment.
From a sample of 1656 participants, 219 were identified as hypertensive, and 37 were identified as hypotensive. Each of these two groups was compared with normotensive individuals matched by age, education and sex. Source memory performance and working memory performance were assessed through computerized tasks.
Source memory accuracy was poorer in hypotensive and hypertensive individuals than in normotensive individuals, and spatial working memory discrimination was inferior in hypertensive participants compared to normotensive individuals.
Blood pressure impairment should be considered a major concern because it has been linked to severe cardiovascular and cerebrovascular diseases. Furthermore, here we show that it has negative effects on the two types of memory that are most essential for preserving a self-sufficient lifestyle.
由于结果存在差异，慢性低血压和高血压对记忆的影响尚不清楚，部分原因是参与者的分类错误。本研究旨在比较诊断为低血压或高血压的个体与血压正常的个体在源记忆和工作记忆表现上的差异。高血压和低血压患者正在接受治疗。
在 1656 名参与者中，有 219 名被诊断为高血压，37 名被诊断为低血压。将这两组患者与通过年龄、教育程度和性别匹配的血压正常的个体进行比较。通过计算机化任务评估源记忆表现和工作记忆表现。
与血压正常的个体相比，低血压和高血压患者的源记忆准确性较差，高血压患者的空间工作记忆辨别力较差。
应考虑血压受损是一个主要问题，因为它与严重的心血管和脑血管疾病有关。此外，我们在这里表明，它对维持自给自足的生活方式最重要的两种记忆类型有负面影响。
