Cognitive Functions and Cognitive Reserve in Relation to Blood Pressure Components in a Population-Based Cohort Aged 53 to 94 Years
Figure 1
Vector analysis of the pair of variables “systolic blood pressure; diastolic blood pressure.” The points and the 95% confidence ellipses represent the mean values of systolic and diastolic pressure among subjects with normal (●) and low mini-mental state examination (a), memory with interference at 10 seconds, (b) and clock drawing test (c). The vector of impairment (arrow) is directed towards higher values of both systolic and diastolic blood pressure.
