Two women (43- and 55-year-old) patients showed normal MRI, inflammatory cerebrospinal fluid (CSF) findings, and moderate response to immunotherapy in long-term follow-up. A broad panel of antibodies was negative for the 43-year-old patient. However, indirect immunohistochemistry showed serum\/CSF antibodies with a distinctive reactivity pattern on rat brain sections. The 55-year-old patient showed anti-glutamic acid decarboxylase in serum and CSF. Five control SS patients without neurological symptoms did not have anti-neuronal antibodies. Anti-neuronal antibody investigation may contribute to the differential diagnosis of neurological involvement in SS.<\/jats:p>","DOI":"10.4103\/ant.ant-d-25-00027","type":"journal-article","created":{"date-parts":[[2026,8,6]],"date-time":"2026-08-06T08:01:02Z","timestamp":1786003262000},"page":"237-241","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Anti-Neuronal
