Inverse relationship between cerebrovascular lesions and severity of lewy body pathology in patients with lewy body diseases.
J Neuropathol Exp Neurol. 2010 May; 69(5):442-8.JN

Abstract

Cerebrovascular pathology is a major cause of stroke and mortality. Studies on prevalence of cerebrovascular pathologies in dementia with Lewy bodies (DLBs) and Parkinson disease (PD) patients are scarce and contradictory. We aimed to determine the prevalence and severity of cerebrovascular pathologies in DLB and PD and to analyze their relationship to LB pathology. The prevalence and severity of atherosclerosis in the circle of Willis, cerebral amyloid angiopathy, cerebral infarcts, hemorrhages, small-vessel disease, white matter lesions, including the Consortium to Establish a Registry for Alzheimer Disease (CERAD) protocol as well as Braak neurofibrillary tangle stages for AD pathology were analyzed in autopsy-verified DLB (n = 13), PD (n = 102), and control subjects (n = 53). In all patient groups, the extent of LB pathology was inversely correlated to the severity of most vascular pathologies (atherosclerosis, infarcts, and small-vessel disease; all p < 0.05). By contrast, cerebral amyloid angiopathy, CERAD, and Braak neurofibrillary tangle stages were positively correlated with LB pathology (p < 0.05). Whereas the overall prevalence and severity of small-vessel disease, infarcts, hemorrhages, and white matter lesions were comparable among both disease groups, the extents of atherosclerosis, cerebral amyloid angiopathy, CERAD, and Braak neurofibrillary tangle stages were significantly higher in DLB than in those of PD patients (p < 0.05). Microinfarcts were statistically more prevalent in each patient group than in controls, whereas gross infarcts predominated in controls (p < 0.05 each). In conclusion, DLB and PD patients with advanced LB pathology were less likely to show severe cerebrovascular disease or history of stroke.
