Leukoaraiosis Correlated with Cerebral Hypoperfusion in Vascular Dementia Stroke 22:609-614, Kawamura,J.,et al, 1991 See this aricle in Pubmed Article Abstract Leukoaraiosis quantified by computerized densitometric measurements of reduced Hounsfield numbers was correlated with local cerebral blood flow on the same computed tomographic images of 35 patients with multi-infarct dementia and 16 age-matched elderly normal volunteers.The ratio for area of frontal leukoaraiosis to total area of parenchyma among the patients was significantly greater than that among the normal volunteers(5.8+or-2. 3%compared with 3.1+or-1.3%,p<0.001).Severity of leukoaraiosis around the frontal horns of the lateral ventricles correlated significantly with severity of leukoaraiosis of the centrum simiovale adjacent to the bodies of the lateral ventricles.Cerebral blood flow values for all representative cerebral regions except the parietal white matter were reduced among the patients compared with the normal volunteers. Multivariate regression analysis revealed that reduced cerebral perfusion in the putamen and thalamus correlated significantly with the severity of the leukoaraiosis.Cerebral hypoperfusion in territories supplied by deep penetrating arteries may contribute to the pathogenesis of leukoaraiosis.
