An auditory test battery composed of seven behavioral and electrophysiologic measures, in addition to pure tone testing, was administered to 33 subjects with definite multiple sclerosis. More than 40% of the subjects with normal peripheral hearing presented with subjective complaints of hearing difficulties. Auditory brainstem response (ABR) was found to be(More)
Monosyllabic rhyme words were dichotically presented to normal and complete split-brain subjects. In the normal adult population, only one of the words in the dichotic condition was identified. Hence, normal performance was about 50%, with a small but significant right-ear advantage. The split-brain patients yielded the expected marked left deficit, as seen(More)
A follow-up report on the dichotic digits test (DDT) demonstrates that this procedure has good sensitivity to central auditory nervous system (CANS) pathology while remaining relatively resistant to mild-to-moderate high-frequency cochlear hearing loss. The DDT's test-retest reliability and short administration time make it an attractive screening procedure(More)
1. There appears to be a relationship among the improved overall behavior of this patient, anatomical changes in the brain, and enhanced performance of both psychophysical and electrophysiological central auditory tests.2. The right-sided peripheral hearing loss was one of the primary indicators for further diagnostic workup, but probably is unrelated to(More)
The ABR interaural latency difference (ILD) from 15 patients with brain stem lesions was compared to the ILDs from patients with VIIIth nerve tumors, cochlear pathology, and a normal control group. All patients in the study had to meet the criteria of bilaterally symmetrical hearing for pure-tone thresholds in order to offset the effect of hearing loss on(More)
Since the inception of the auditory brain stem response (ABR) as a test of brain stem integrity in the mid-1970s, much has been learned about its advantages and limitations. Although ABR remains perhaps the best audiologic test for brain stem disorders, its sensitivity is dependent on the type and various characteristics of the lesion. Behavioral tests,(More)
