Abstract

Insights

The rare co-occurrence of Multiple Sclerosis (MS) and Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL) presents diagnostic challenges. Early inflammatory presentations in CADASIL may indicate a need for immunomodulatory therapies, similar to MS treatment.

Area of Science:

  • Neurology
  • Genetics
  • Immunology

Background:

  • Co-occurrence of Multiple Sclerosis (MS) and Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL) is exceptionally rare.
  • Emerging cases of

Observation:

  • A case of a 25-year-old presenting with cognitive decline, gadolinium-enhancing MRI lesions, and inflammatory cerebrospinal fluid (CSF) is detailed.
  • This presentation raises diagnostic questions regarding "inflammatory CADASIL" versus coexisting MS and CADASIL.

Findings:

  • A literature review identified nine cases of CADASIL with inflammatory presentations.
  • Treatments in these cases varied, including intravenous steroids and MS immunomodulatory therapy.

Implications:

  • Individuals with CADASIL exhibiting immune-mediated inflammatory features may benefit from immunomodulatory treatments.
  • This highlights the importance of considering inflammatory etiologies in CADASIL patients and potential overlap with MS diagnostic criteria.
