Abstract

Objectives

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.

Method

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.

Results

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.

Conclusion

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.

低血压和高血压对源记忆和工作记忆的影响

摘要

目标

由于不同的结果，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错误分类。本研究的目的是比较被诊断患有低血压或高血压的个体的源记忆和工作记忆表现与正常血压参与者的表现。高血压和低血压患者正在接受治疗。

方法

在 1656 名参与者的样本中，219 人被确定为高血压，37 人被确定为低血压。将这两组中的每一组都与按年龄、教育程度和性别相匹配的正常血压个体进行比较。通过计算机化任务评估源记忆性能和工作记忆性能。

结果

与正常血压个体相比，低血压和高血压个体的源记忆准确性较差，与正常血压个体相比，高血压参与者的空间工作记忆辨别能力较差。

结论

血压受损应被视为一个主要问题，因为它与严重的心脑血管疾病有关。此外，我们在这里表明它对两种类型的记忆有负面影响，而这两种类型的记忆对于保持自给自足的生活方式最为重要。
