Leucoencéphalopathies vasculaires chez des patients sans facteur de risque vasculaire ni mutation de NOTCH3Â : description clinique et radiologique

The identification of vascular leukoencephalopathy in young patients without any vascular risk factors should lead the clinician to perform a complete work-up to search for treatable conditions including high blood pressure. Patients with vascular leukoencephalopathy usually present with astasia-abasia. In this context, cerebral MRI, cannot perfectly discriminate between patients with CADASIL from those with acquired small-vessel disease of the brain so that sequencing of NOTCH3 gene exons 2-24 is recommended.
