- Brainstem auditory evoked responses (BAERs) were studied in eighteen patients
with brainstem strokes, and the results were correlated with the clinical and radiological localization.
The absence of all ipsilateral waves (or all except wave I) was caused by acute, relatively
extensive lesions impinging on the inferolateral part of the pons.
The late wave abnormalities (III-V delay or poor wave V formation) which more often
occurred on the contralateral side of the lesions, generally resulted from dorsally situated
The pontomesecephalic lesions sparing dorsal or inferolateral areas as well as medullary
lesions tended to produce normal BAERs.
We conclude that BAER is an effective clinical aid in localizing braintem stroke if it is interpreted
with respect to the three dimensional brainstem auditory pathway.
