Abstract

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a hereditary CNS disease with autosomal dominant inheritance caused by NOTCH3 gene mutations. Typically, CADASIL manifests with headaches, recurrent strokes, and progressive cognitive decline. Neuroimaging plays an important diagnostic role as it reveals multiple lacunar infarcts in the basal ganglia, brainstem, and cerebellum, as well as focal white matter lesions and diffuse leukoaraiosis-type changes. CADASIL can sometimes have other symptoms and mimic different phenotypes atypical of the disease. We hereby present two genetically confirmed CADASIL cases that manifested with predominantly cerebellar or essential tremor combined with cognitive and affective disturbances. The main principles of diagnosis of this disease characterized by clinical polymorphism are discussed.
