Abstract: | Context:With advances in neuroimaging, traditional views regarding the clinicoanatomic correlation in stroke patients with aphasia are being challenged and it has been observed that lesions at a given cortical or subcortical site may manifest with different aphasia profiles.Aims:To study as to whether there is a strict clinicoanatomical correlation between the type of aphasia and lesion site in patients with first ever stroke.Settings and Design:Observational study, based in a tertiary care center.Materials and Methods:Stroke patient''s ≥18 years of age were screened and those with first ever stroke and aphasia were subjected to a detailed stroke workup and language assessment using the Hindi version of Western Aphasia Battery (WAB). Statistical analysis was done with χ2 test with Yates correction and Kruskal-Wallis test. The level of significance was set at P < 0.05.Results:Overall aphasia was detected in 27.9% of the 260 screened cases with stroke. Amongst 60 cases with first ever stroke and aphasia, the aphasia type was: Global (33.33%), Broca''s (28.3%), transcortical motor (13.33%), transcortical sensory (10%), Wernicke''s (8.33%), anomic (5%), and conduction (1.67%) aphasia. A definite correlation between the lesion site and the type of aphasia as per the traditional classification was observed in 35% cases only.Conclusions:No absolute correlation exists between the lesion site and the type of clinical aphasia syndrome in majority of the patients with cortical and subcortical stroke. |
