Progressive dementia developed during a 15‐month period in a 56‐year‐old woman with serologically and clinically documented primary Sjögren's syndrome. Findings from magnetic resonance imaging and angiography were normal, but a brain biopsy disclosed perivascular lymphocytic inflammation in leptomeningeal and parenchymal vessels. Treatment with high‐dose corticosteroids produced rapid and nearly complete resolution of the dementia.
