RESUMEN
Objective: As the cerebrovascular diseases [CVD] are among the most common anomalies that are directly or indirectly affecting the auditory cortex, studying in this area is important. We tried to evaluate the function of CANS in a group of 50-70 years old cerebrovascular accident [CVA] patients with no hearing complaint by competing sentences test [CST] as a dichotic speech test
Method and Material: This cross-sectional analytical study was conducted at Loghman-e-Hakim hospital between 22, august 1999 and 20, July 2000 in a group of 30 normal 50-70 years old persons and a group of 40 patients with CVA including 30 patients with abnormal CT scan and 10 patients with normal CT scan
Results: The results point out the mean scores of CST in the normal group were at normal range [80-100%] in both ears. And mean scores of CST decreased in the patients groups. There were significant difference between mean scores of CST in the patients with CVA and control groups
Conclusion: CST seems to be a valuable test in the CANS test batteries for the cerebrovascular diseases
