Insights
Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL) is a genetic brain disease causing strokes and dementia. Currently, no specific treatment exists for this progressive condition.
Area of Science:
- Neurology
- Genetics
- Vascular Biology
Context:
- CADASIL is a rare, inherited cerebrovascular disorder affecting small arteries, primarily in the brain.
- It manifests in mid-adulthood with symptoms including recurrent ischemic events, migraines, mood disorders, and cognitive decline.
- MRI reveals characteristic white matter changes, particularly leukoencephalopathy.
Purpose:
- To describe the clinical and genetic features of Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL).
- To highlight the progressive nature and significant impact of CADASIL on affected individuals.
Summary:
- CADASIL is an autosomal dominant arteriopathy caused by mutations in the Notch3 gene on chromosome 19.
- The disease leads to progressive neurological deficits, including strokes, dementia, and mood disturbances.
- Onset typically occurs in mid-adulthood, with a mean survival of approximately twenty years post-diagnosis.
Impact:
- CADASIL represents a significant challenge in neurodegenerative disease management due to the lack of specific treatments.
- Understanding its genetic basis and clinical progression is crucial for developing targeted therapies and improving patient care.
- This research underscores the importance of early diagnosis and genetic counseling for families affected by CADASIL.
Abstract:
CADASIL (cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy) is a diffuse disease of small arteries, predominating in the brain. It starts during mid-adulthood and is characterized by recurrent ischaemic events (transient or permanent), attacks of migraine with aura, severe mood disorders, subcortical dementia and at MRI white periventricular leukoencephalopathy. CADASIL is an autosomal dominant disease. The gene Notch3 on which the mutation was detected is located on chromosome 19. There is so far no specific treatment and death occurs after a mean of twenty years.
