To clarify the characteristics of CADASIL in Japan, we performed clinical and genetic investigations for six patients from 5 Japanese families diagnosed as CADASIL. We identified that the onset of focal neurologic deficits ranged from 38 to 63 years old (mean 49 +/- 9.4 yrs) and the occurrence rates of main neurologic symptoms and signs were 1/6 for migraine, 3/6 for recurrent stroke episodes, 6/6 for dementia, and 4/6 for pseudobulbar palsy. The marked narrowing of retinal arteries were observed in 3/6. The notch 3 mutations were all found in exon 4. Although other several families shared similar phenotype of CADASIL, there were no deposition of granular osmiophilic materials within the basal lamina of smooth muscle cells in the arterioles of biopsied muscle and no mutations in the cording regions of notch 3 gene. We investigated prospectively the incidence of CADASIL and CADASIL-like disease in Kumamoto district from 1999 to 2000. One thousand and thirty four patients with stroke were hospitalized in 6 hospitals which have stroke care unit. Among them, 7 patients fulfilled the criteria that were less than 60 years old, lacunar strokes and/or TIA, presence of a family history, and no risk factors such as hypertension, diabetes mellitus, and hyperlipidemia. One of seven patients was diagnosed as CADASIL by DNA analysis. It was suspected the incidences of CADASIL and CADASIL-like disease were not so rare in Japan.

We reviewed 12 patients from 11 Japanese families diagnosed as having CADASIL from 1998 to 2001. The age of onset of focal neurologic deficits ranged from 38 to 71 years (mean: 50.4 +/- 9.8 years). Japanese CADASIL patients rarely had migraine and frequently presented with symptoms of dementia at diagnosis. Notch3 mutations were concentrated in exons 3, 4, and 5. Cysteine was replaced by another amino acid or vice versa in the majority of Japanese CADASIL patients. However, in 2 families, the mutations were not related to cysteine. In the prospective study, 2030 patients with stroke were hospitalized in 6 hospitals with stroke units in the Kumamoto district from 1999 to 2001. Among them, 14 patients fulfilled the criteria of being less than 60 years of age, showing lacunar strokes and/or TIA, presence of a family history, and no risk factors of stroke. One of these 14 patients was diagnosed as having CADASIL by DNA analysis. However, if hyperlipidemia was excluded from the list, 16 patients fulfilled the criteria and 2 patients were diagnosed as having CADASIL by DNA analysis. It was suspected that the incidence of CADASIL is not so rare in Japan. There were some families with CADASIL-like features, but without Notch3 mutations or GOM, suggesting the need for genetic analysis in the future.
