The present study aimed to evaluateone the communicative skills, discourse, in adult right and left hemispheres damaged Persian speaking patients due to cerebrovascular accident (CVA) using the Persian version of the Montreal Protocol for the Evaluation of Communication (M.E.C.).
Findings indicated that damage to the right and left hemispheres of the brain leads to discourse impairments. However, damages to the right hemisphere increases the severity of linguistic impairments more than damages to the left hemisphere. All patients who had the weakest performance in the sub-tests of protocol skills, their temporal lobe was damaged. In RHD, those patients who had the weakest performance in the sub-tests of protocol skills, their damages were located in the temporal lobe. As a result, it seems that damage to the temporal lobe in the right hemisphere of the brain leads to impaired discourse skills. In LHD group, damages to the frontotemporal and temporal-parietal areas in the left hemisphere of the brain cause some impaiments to the discourse skills of LHD patients. Therefore, based on these datas, it may be claimed that there is a direct relationship between the degree of impairments of discourse and pragmatic skills and the location of the brain lesion.
