Primary Sjogren's syndrome with central nervous system involvement.

Abstract

Our findings demonstrate that CNS involvements in PSS have great clinical variability and could precede the classic sicca symptoms by years. Primary Sjogren's syndrome can mimic multiple sclerosis (primary progressive multiple sclerosis or relapsing remitting multiple sclerosis), therefore a screening test for PSS should be considered in suspected cases. A well-defined management protocol awaits studies with larger case numbers.
