To assess the role that age and some vascular risk factors play in the pathogenesis of leukoaraiosis and lacunar infarcts in patients with ischemic stroke, we examined 71 consecutive patients who had undergone magnetic resonance imaging because of clinical suspicion of stroke. We collected data regarding hypertension, diabetes mellitus, cardiac diseases, hypercholesterolemia, and hematocrit, and compared patients with lacunar infarcts to those with cortical or subcortical nonlacunar lesions. Patients were then assigned to one of two age groups, Group A (< or = 66 years), or Group B (> 66 years). We found a significant correlation between the presence and severity of leukoaraiosis and the presence of lacunar infarcts in both groups. In Group A, however, lacunar infarcts were correlated to hematocrit, while in Group B they were correlated to a trend to hypertension. Leukoaraiosis was correlated to hypertension only in Group A. Although we noted a strong correlation between leukoaraiosis and lacunar infarcts suggesting a common small-vessel disease, our data indicate that different pathogenetic mechanisms are involved. We suggest that patients be grouped according to age in future studies on the role that risk factors play in the pathogenesis of leukoaraiosis and lacunar infarcts.
