What is the prognosis for individuals with CADASIL?

Symptoms usually progress slowly. By age 65, the majority of persons with CADASIL have severe cognitive problems and dementia. Some people lose the ability to walk and most become completely dependent due to multiple strokes.[1]

Data on the long-term prognosis come from a large study of 411 individuals, which found that the median age at onset of inability to walk without assistance was 60 years and the median age at onset of being bedridden was 64 years. The median age at death was 68 years with a more rapid disease progression in men than in women. At their time of death, 78% of individuals were completely dependent and 63% were confined to bed. Pneumonia was the most frequent cause of death.[2]
