Summary
Systemic lupus erythematosus (SLE) often involves the central nervous system (CNS) early, with neuropsychiatric symptoms like migraines and depression. Neuroimaging and lab tests aid diagnosis, as CNS involvement remains a leading cause of mortality in SLE patients.
Area of Science:
- Neurology
- Immunology
- Rheumatology
Context:
- Central nervous system (CNS) involvement is increasingly recognized in early systemic lupus erythematosus (SLE), often preceding formal diagnosis.
- Non-focal neuropsychiatric symptoms, including migraines and depression, are clinically predominant in CNS involvement.
- Traditional diagnostic signs of SLE are less reliable for diagnosing CNS involvement.
Purpose:
- To review current literature on the features of CNS involvement in SLE.
- To explore recent pathophysiological models, including autoimmune processes.
- To highlight advancements in diagnosing CNS involvement, such as neuroimmunological tests and 15O-positron emission tomography.
Summary:
- Early CNS involvement in SLE is common, presenting with neuropsychiatric symptoms.
- Advanced diagnostics like neuroimaging and specific lab tests are crucial for early detection.
- Corticosteroids are the preferred pharmacotherapy, though CNS complications remain a significant cause of mortality.
Impact:
- Improved diagnostic strategies for CNS involvement in SLE patients.
- Enhanced understanding of the pathophysiology of cerebral lupus.
- Identification of CNS complications as a critical factor influencing long-term survival in SLE.
