Abstract
-
Brainstem auditory evoked potentials (BAEPs) were evaluated in 22 patients with tuberculous meningitis to determine the incidence of abnormal BAEPs in tuberculous meningitis and the possible effect of variable factors on the incidence of abnormal BAEPs. Of 22 patients tested, 19 (86.4%) had abnormal interpeak latencies in one or both ears. I-III interpeak latenies were increased in 14 patients (63.6%) and III-V interpeak latencies in 7 patients (31.8%). Meningeal enhancement in brain CT or MRI was significantly correlated with abnormal BAEPs, especially with I-III interpeak latencies.
