title: Autosomal dominant migraine with MRI white-matter abnormalities mapping to the CADASIL locus.
abstract: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an autosomal dominant cerebral arteriopathy mapped to chromosome 19 and characterized mainly by recurrent subcortical ischemic strokes and extensive white-matter signal abnormalities (WMAs) on magnetic resonance imaging. Other clinical features include migraine attacks and progressive subcortical dementia. Herein, we describe several members of the same family who suffered migraine attacks, mostly with aura, associated with WMAs, segregating with an autosomal dominant pattern of inheritance. One individual had a progressive subcortical dementia with similar WMAs. Although ischemic stroke, one of the hallmarks of CADASIL, was not present in this family, we hypothesized that the present disorder resulted from an alteration of the CADASIL gene. Genetic linkage analysis, using four chromosome 19 markers spanning the CADASIL locus, supports this hypothesis.
