Insights

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a genetic small vessel disease caused by NOTCH3 mutations. This review explores CADASIL pathogenesis, diagnosis, and treatment, highlighting NOTCH3

Area of Science:

  • Neurology
  • Genetics
  • Vascular Biology

Background:

  • Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is the most common hereditary cerebral small vessel disease (CSVD).
  • Pathologically, CADASIL involves a non-atherosclerotic, non-amyloid angiopathy affecting cerebral arteries.
  • NOTCH3 gene mutations were identified as the cause in 1996, though other genetic CSVDs mimic the phenotype.

Purpose of the Study:

  • To review current progress in CADASIL, focusing on clinical, neuroimaging, pathological, and genetic aspects.
  • To provide insights into the pathogenesis, diagnosis, and personalized therapy of hereditary CSVDs.
  • To highlight the role of NOTCH3 mutations in CADASIL and differential diagnoses.

Main Methods:

  • Literature review of studies on CADASIL and other hereditary CSVDs.
  • Synthesis of current knowledge on clinical presentation, neuroimaging findings, and pathology.
  • Analysis of genetic factors, diagnostic criteria, and therapeutic strategies.

Main Results:

  • NOTCH3 mutations are central to CADASIL, a well-recognized hereditary disorder.
  • Other genetic CSVDs can present similarly, necessitating careful differential diagnosis.
  • Understanding NOTCH3's role in pathogenesis remains an active area of research.

Conclusions:

  • CADASIL is a distinct NOTCH3-associated CSVD, but shares features with other hereditary CSVDs.
  • Comprehensive understanding of clinical, genetic, and pathological aspects is crucial for diagnosis and management.
  • Further research is needed to elucidate the precise role of NOTCH3 in CADASIL pathogenesis.
