Abstract:
Visit-to-visit blood pressure variability has been shown to be an independent risk factor for stroke and cognitive impairment. However, the underlying mechanisms are not fully understood. Artery remodeling and silent cerebral injury are suggested to be involved in the relationship between visit-to-visit blood pressure variability and cognitive impairment. The present review article summarizes the recent literature on these topics. Here we review visit-to-visit blood pressure variability, artery remodeling, silent cerebral injury and an issue regarding the impact of these components on dementia including Alzheimer's disease.

Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart...
Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
