Neuropathological correlates of temporal pole white matter hyperintensities in CADASIL.
BACKGROUND AND PURPOSE White matter (WM) hyperintensities on MRI or leukoaraiosis is characteristic of stroke syndromes. Increased MRI signals in the anterior temporal pole are suggested to be diagnostic for cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), with 90% sensitivity and 100% specificity. The structural correlates of these specific ...
متن کاملCerebral hemodynamics and white matter hyperintensities in CADASIL.
Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a hereditary small-vessel disease caused by mutations in the NOTCH3 gene on chromosome 19. On magnetic resonance imaging (MRI), subcortical white matter hyperintensities and lacunar infarcts are visualized. It is unknown whether a decrease in cerebral blood flow or cerebrovascular reactivity ...
متن کاملWhite matter hyperintensities in migraine
Case-control studies showed that migraine is associated with ischemic stroke. Studies assessing the prevalence of white matter lesions (WML) in migraine however, reported conflicting results, possibly attributable to selection bias by recruiting only severe cases. We conducted a population-based MRI study of migraineurs with aura (N=161), migraineurs without aura (N=134) and controls (N=140), 3...
متن کاملMTI of white matter hyperintensities.
The severity of tissue changes associated with incidental white matter hyperintensities (WMH) in the elderly cannot be sufficiently determined by conventional MRI. We, therefore, performed a regional analysis of the magnetization transfer ratio (MTR) maps obtained on a 1.5 T scanner from 198 neurologically asymptomatic participants of the Austrian Stroke Prevention Study (mean age 70, age range...
متن کاملConfluent thalamic hyperintensities in CADASIL.
BACKGROUND CADASIL is responsible for diffuse hyperintensities in the white matter on FLAIR images. These lesions are often associated with focal lesions in the basal ganglia such as lacunar infarctions. The prevalence and significance of diffuse or confluent thalamic hyperintensities (CTH) remain unknown. METHODS The frequency of hyperintensities on FLAIR images in the thalamus was assessed ...
