Introduction: Aphasia is a common manifestation of stroke and evaluation of relationships of aphasia and brain topography could lead to better understanding of cognitive neurophysiology.
Methods: 100 stroke patients with aphasia admitted in Valie-Asr hospital, Khorasan since April 2003 were enrolled in this prospective cross-sectional study. Diagnosis of stroke and aphasia was made by a neurologist and topography of involved cerebrovascular territories confirmed by topographic maps of brain in CT scan.
Results: Global, Broca and Wernicke subtypes of aphasia constituted 52%, 40% and 6% of the cases, respectively. Based on the usual nourishment of Broca and Wernicke areas by anterior and posterior cortical branches of the middle cerebral artery, 79% of Global, 47% of Broca and 50% of Wernicke aphasias had compatible infarct topography. The infarct topography in other cases was not congruent with the involved linguistic areas of their brain.
Conclusion: Specific cerebrovascular topography for subtypes of aphasia in stroke patients was not found. The effects of cerebrovascular lesions on linguistic functions are not predictable by their topography in CT scan.
