- Abstract
- Background
Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL)
is an inherited arteriopathy caused by mutation in the Notch 3 gene. Cognitive impairment, which is the second most
frequent clinical manifestation, worsens with recurrent stroke. Comparison studies between the pre- and poststroke
phases in CADASIL have not yet been performed in Asia. Here we describe the clinical characteristics of both the pre-
and poststroke phases and identified the risk factors for stroke in CADASIL.
Methods
Fifty-three consecutive patients were investigated. Patients were divided into two groups depending on the
presence (poststroke group; n=31) or absence (prestroke group; n=22) of clinically overt stroke. All patients underwent
an MRI scan with the same protocol. Cognition was assessed by applying detailed neuropsychological tests.
Results
The poststroke group exhibited an increase in lacunae and cerebral microbleeds. The memory scores on the
Alzheimer’s Dementia Assessment Scale cognitive subscale and the number of correct Stroop color-naming scores were
lower in the poststroke group than in the prestroke group. Hypertension was more prevalent in the poststroke group,
while chronic headache was more prevalent in the prestroke group.
Conclusions
These findings suggest that cerebral microbleeds as well as lacunae predict the risk of clinically overt
stroke, which leads to a worsening of frontal-lobe function in CADASIL. Key Words: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL),
