Relationship between sleep quality and Executive Functions in patients with high blood pressure

Background and Aim : Objective in current study: The purpose of this study was to investigate the relationship between sleep quality and executive functions in patients with high blood pressure. Study community: 40 subjects between 37-55 years old with high blood pressure were selected in medical clinics in Tehran City in 2017. They were matched with 40 healthy person who didn’t blood pressure. They were matched in age, sex, education level and smoking history. Then the Pittsburgh Sleep Quality Index (PSQI) was used to assess sleep quality in both groups and tests of assessment (Visual prob task and N-Back) of attentional bias and working memory were implemented on them for assessing execute functions. Research design: The current study was a correlation researchMethods : First, the Pittsburgh Sleep Quality Index (PSQI) was filled and then the tests of assessment (Visual prob task and, N-Back) of attentional bias and working memory were implemented on them. The collected data were analyzed with SPSS software through Two-way analysis of Variance.Results : Total PSQI score, sleep latency, sleep duration, average use of sleep aids and sleep disturbances in patients with high blood pressure were significantly higher than the control group. When executive functions impairment were compared, statistically significant relationship was established between cognitive impairment and sleep quality.Conclusion : The findings indicated that bad sleep quality in high blood pressure is common as well as executive function deficits. This showed that there is relationship between sleep quality and executive function in high blood pressure. But it is noticeable that know, improving sleep quality improves work memory and attentional bias‚ performance or decreasing blood pressure improves working memory, attentional bias and sleep quality. It is necessary more studies to find the best answer for that.
