Neurologic complications of primary Sjogren's syndrome

Primary Sjogren's syndrome has a wide clinical spectrum, ranging from an exocrinopathy to a systemic process and even extending to B-lymphocyte neoplasia. We describe a patient with this syndrome who developed central nervous system involvement manifested by involuntary dystonic movements of the mouth and larynx. We believe that the neurological involvement in this patient is part of his basic disease. Further studies are required to define more accurately the frequency, severity and spectrum of the neurological manifestations associated with primary Sjogren's syndrome.
