Evaluation of brainstem auditory potential in brucellosis patients with and without neurological involvement.

This study investigated the changes in brainstem auditory evoked potentials (BAEPs) in acute phase of brucellosis. Twenty-two patients with brucellosis without neurologic involvement and seven patients with neurobrucellosis were included. BAEPs were evaluated before treatment. No patient had a symptom of hearing loss. Patients who had neurologic involvement did not show any abnormalities in their BAEPs recording. This study suggests that patients with brucellosis who are in the acute phase of the disease with or without neurological involvement may have normal BAEPs. BAEPs do not seem to be a sensitive method for central nervous system involvement of brucella patients in the acute phase of the disease.
