Abstract

This case report describes a 32-year-old male with a familial history of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), presenting with right-sided weakness and visual disturbances. The symptoms, consistent with a transient ischemic attack (TIA), resolved spontaneously. Subsequent evaluation, including MRI brain imaging, revealed a high T2 signal in subcortical white matter in the frontal and parietal lobes, consistent with CADASIL. Positive NOTCH3 testing confirmed the diagnosis, leading to the initiation of antiplatelet and statin therapy under the care of both stroke and neurology teams.

How strong is the evidence?

Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
