Brainstem auditory evoked potentials in patients with primary Sjögren's syndrome without central nervous system involvement.

This study confirms that in pSS patients without clinical central nervous system impairment, auditory pathway disturbances could be found. Disorders of brain bioelectrical activity may be a consequence of ongoing autoimmune process. Key Points • BAEP abnormalities confirmed the clinically observed involvement of the central nervous system in patients with pSS. • Brain bioelectrical activity dysfunctions in pSS patients may be a consequence of ongoing inflammatory and/or immunological processes.
