E) all of the above

The results of CT and structural MRI studies of aphasic patients show that not all aphasic patients have damage limited to the classic Wernicke-Geschwind areas, indicating a more complex relationship between brain damage and aphasia. Many aphasics indeed have extensive damage that includes subcortical white matter, not just the cortical areas traditionally associated with language. Additionally, the pattern of damage often correlates with the type of aphasia, where anterior lesions typically result in expressive deficits and posterior lesions in comprehension deficits, supporting the comprehensive statement that all of the provided options are correct.
