Key result
Higher variability in systolic and diastolic blood pressure was associated with poorer cognitive performance, especially in unsuccessfully treated hypertensive individuals with BP ≥140/90 mm Hg.

Is blood pressure variability associated with cognitive performance?
Higher measurement-to-measurement blood pressure variability is associated with poorer cognitive performance, particularly in unsuccessfully treated hypertensive individuals.

Does not support practice changes; leaves open causal role of BP variability in cognitive decline among uncontrolled hypertensives.
Crichton et al. (2014) conducted a cross-sectional in Blood pressure variability and cognitive performance (n=972). Blood pressure variability was evaluated on Cognitive performance. Higher variability in systolic and diastolic blood pressure was associated with poorer cognitive performance, especially in unsuccessfully treated hypertensive individuals with BP ≥140/90 mm Hg.
