Central nervous system (CNS) involvement in rheumatic diseases presents diagnostic challenges. This review synthesizes knowledge on diagnosing and managing CNS issues in common rheumatic conditions, aiding clinical decision-making.
Area of Science:
- Neurology
- Rheumatology
- Immunology
Background:
- Central nervous system (CNS) involvement is a complex challenge in autoimmune rheumatic diseases.
- Existing reviews often focus on specific rheumatic conditions rather than a broader syndromic approach.
Purpose of the Study:
- To synthesize current knowledge on the diagnosis and management of CNS manifestations in prevalent adult rheumatic conditions.
- To shift focus from neurological syndromes to rheumatological diagnoses.
Main Methods:
- Narrative review of MEDLINE-searched articles (2019-2024) using keywords: "central nervous system", "rheumatic diseases", "systemic lupus erythematosus", "rheumatoid arthritis", "Sjögren syndrome", "vasculitis".
- Exploration of pathophysiological mechanisms, diagnostic tools (syndromic reasoning, autoantibodies, imaging), differential diagnoses, and treatment options.
Main Results:
- Discusses the link between autoimmunity and CNS pathology.
- Emphasizes diagnostic tools like autoantibody profiles and imaging for inflammatory activity.
- Provides a stepwise approach to neurological syndromes with diagnostic flowcharts and updated treatments.
Conclusions:
- Highlights the importance of a semiology-based approach combined with advanced diagnostics for CNS rheumatic manifestations.
- Suggests future research incorporating advanced imaging techniques like functional MRI and MR spectroscopy.
