Abstract
Different types of migraine have been reported in 20-40% of patients with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). We describe a novel migrainous manifestation of CADASIL consisting in status migrainosus and persistent aura without infarction. The symptoms resolved after i.v. treatment with lorazepam and mannitol.
