Abstract

Background and Aim: Cerebrovascular accident is a neurological disorder involves central nervous system. Studies have shown that it affects the outputs of behavioral auditory tests such as dichotic auditory verbal memory test. The purpose of this study was to compare this memory test results between patients with cerebrovascular accident and normal subjects.
Methods: This cross-sectional study was conducted on 20 patients with cerebrovascular accident aged 50-70 years and 20 controls matched for age and gender in Emam Khomeini Hospital, Tehran, Iran. Dichotic auditory verbal memory test was performed on each subject.
Results: The mean score in the two groups was significantly different (p<0.0001). The results indicated that the right-ear score was significantly greater than the left-ear score in normal subjects (p<0.0001) and in patients with right hemisphere lesion (p<0.0001). The right-ear and left-ear scores were not significantly different in patients with left hemisphere lesion (p=0.0860).
Conclusion: Among other methods, Dichotic auditory verbal memory test is a beneficial test in assessing the central auditory nervous system of patients with cerebrovascular accident. It seems that it is sensitive to the damages occur following temporal lobe strokes.
