Aims and objectives:
• To assess patients with cerebrovascular accidents (CVA), in order to ascertain the presence and types of language deficits.
• Assess for any possible association between lesion site and pattern and degree of language impairments.
• To determine if the degree of language deficits are more in left hemisphere pathology.
Materials and methods: An observational study was conducted over a period of 1 year in the Department of ENT and Head-Neck Surgery and Department of Neuromedicine in a Tertiary Care Hospital. Poststroke patients were evaluated. Stable patients were selected. Both hemorrhagic and ischemic stroke patients were included. We had used the Western Aphasia Battery (WAB) to assess the faculty of Language in the study population and computed the Aphasia Quotient, based on which we categorized language function.
Results: In our study, the number of patients with Infarction as the pathologic process was greater than those with hemorrhage. A total of 40% of cases had exclusively subcortical lesions. In our study, young stroke (stroke in patient under 50 years of age), was present in 14%. Aphasia was present in 40% of the patients. Crossed aphasia was seen in one patient (4%). Based on the aphasia quotient obtained from WAB, we categorized the aphasia as mild (4%), moderate (12%), and severe (24%). We had a preponderance of nonfluent aphasia.
Conclusion: The frequency of poststroke aphasia was higher in our study (40%) than that seen in earlier studies. We have seen a preponderance of nonfluent aphasia in our study with global aphasia (50%) being the commonest subtype. Significant association (p < 0.05) was found between left-sided lesions and the presence of aphasia.
