title: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL).
abstract: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a recently described neurovascular disease affecting young to middle age individuals. The disease is caused by mutations in the Notch3 gene located in the short arm of chromosome 19. Clinically, the disease is characterized by migrainous headaches (with or without aura), mood disturbances, focal neurologic deficits, transient ischemic attacks, strokes, and dementia. Pathologically, the disease is characterized by a stereotypic degeneration of the arterial walls (especially in the intracranial compartments) with deposition in the media of a nonatheromatous, nonamyloidotic substance that under the electron microscope (EM) appears as a granular osmiophilic material (GOM), pathognomonic for the disease. The nature of the GOM is undetermined and the pathogenesis remains to be elucidated. A review of current literature in English language is presented on the clinical, radiologic, pathologic, and genetic features of CADASIL.
