Table 2 Mean (SD) brain MRI characteristics of the sample

MRI variablesControls, n = 67Stroke/TIA, n = 97NCI, n = 39VCI, n = 37VaD, n = 18ANOVA*p valueVCI vs VaD(VCI + VaD) vs NCINCI vs Con
The scores on visual ratings are presented. NCI + VCI + VaD = 94. The remaining three stroke subjects had non-VaD dementia/cognitive impairment.
* Analysis of variance (ANOVA) controlling for age and multiple comparisons (with Bonferroni correction).
TIA = transient ischemic attack; NCI = no cognitive impairment; VCI = vascular cognitive impairment; VaD = vascular dementia; Con = controls; VBR = ventricle to brain ratio; N/A =not applicable; WMH = white matter hyperintensities; FLAIR = fluid-attenuated inversion recovery; GMH = gray matter hyperintensities.
