## Resource

This study analyzes a forty-year cohort of 216 patients at the Mayo Clinic to examine the diverse presentations and clinical outcomes of primary central nervous system vasculitis (PCNSV) . The research identifies that vessel size and histopathologic patterns are the primary drivers of disease heterogeneity, distinguishing between small vessel involvement and medium or large vessel disease . Patients with small vessel disease frequently present with cognitive issues and have better treatment responses, while large vessel involvement is linked to more frequent strokes and a rapidly progressive course. Lymphocytic vasculitis was found to have the most favorable prognosis, whereas granulomatous and necrotizing types were associated with higher disability and mortality rates. The findings emphasize that early recognition of high-risk subsets and the use of aspirin alongside immunosuppressive therapy may significantly improve long-term remission. Overall, the data provides a framework for tailoring treatments based on specific diagnostic indicators to manage this rare and complex neurological condition.
