Why the study?
Blood pressure variability has been suggested as a clinical indicator for cognitive dysfunction, but findings from clinical studies remain variable.
Does higher systolic blood pressure variability increase the risk of cognitive decline or dementia?
Does higher systolic blood pressure variability increase the risk of cognitive decline or dementia?
Higher systolic blood pressure variability may serve as a clinical indicator for an increased risk of all-cause dementia, particularly in older adults and over shorter timeframes.
No takes yet. Share an insight, caveat, or question.
May flag higher all-cause dementia risk in older adults; leaves open causal links and effects on measured cognitive decline.
Chiu et al. (2021) studied this question.
