Key result
An increase in diastolic pressure of 10 mmHg showed inconsistent associations with cognitive tests (e.g., immediate memory MD 1.0; 95% CI -0.04 to 1.9), suggesting it is not a major contributor.

Diastolic BP shows inconsistent cognitive links in elderly; cross-sectional data leave open any causal role and require prospective confirmation.

Is blood pressure associated with cognitive function in the elderly?
Mean Difference: 1 (95% CI -0.04–1.9)
Blood pressure does not appear to be a substantial contributor to cognitive status in the elderly.
Scherr et al. (1991) conducted a cross-sectional in Cognitive function (n=3,809). Diastolic blood pressure increase of 10 mmHg was evaluated on Immediate memory percentile score (MD 1.0, 95% CI -0.04 to 1.9). An increase in diastolic pressure of 10 mmHg showed inconsistent associations with cognitive tests (e.g., immediate memory MD 1.0; 95% CI -0.04 to 1.9), suggesting it is not a major contributor.
