A Comparison of Language Features Between Patients With Alzheimer Disease and Their Healthy Counterparts

Introduction: alzheimer disease (ad) is a neurological disorder associated with the progressive damage of memory and problems in communication and language skills. the examination of language in ad was less studied; therefore, this research aimed to compare linguistic characteristics between ad patients and their healthy counterparts. materials and methods: a total of 32 patients with ad (16 women and 16 men) with an mean±sd age of 77±7.41 years, and their healthy peers (19 women and 13 men) with an mean±sd age of 81.34±6.04 years participated in this study. both groups were evaluated with the persian bedside version of western aphasia battery. the results were assessed by the independent t test. the significance level was set at less than 0.05. results: the mean scores of each test and the general criterion for the adversity quotient index were significant between the two groups (p<0.001). the highest difference was in continuous and naming indices, and the least difference was seen in the repeat index. conclusion: the ad considerably affects all oral language skills; therefore, patients are significantly weaker than healthy individuals.
