Brain stem auditory evoked responses and visual evoked responses in children with tubercular meningitis.

ABSTRACT

Thirty two patients between 6 months and 14 years of age with tubercular meningitis were evaluated for brain stem auditory evoked response (BAER) and Visual evoked responses (VER), within 7 days of admission. Absolute latencies and interpeak latencies were compared with values obtained from normal children. BAER abnormality was found in 56.25% and VER in 28%children, respectively. BAER abnormality correlated with Glasgow Coma Scale at admission and discharge, stage of meningitis, raised intracranial pressure, seizure activity, and poor outcome. VER abnormality correlated with abnormal fundus findings only.
