Aphasia, also known as dysphasia, [a] is an impairment in a person’s ability to comprehend or formulate language because of damage to specific brain regions. [2] The major causes are stroke and head trauma; prevalence is hard to determine, but aphasia due to stroke is estimated to be 0.1–0.4% in developed countries. [3]
Expressive aphasia can also be caused by trauma to the brain, tumor, cerebral hemorrhage [25] and by extradural abscess. [26] Understanding lateralization of brain function is important for understanding which areas of the brain cause expressive aphasia when damaged. In the past, it has been believed that the area for language production ...
He did this on the basis of the location of brain injuries that caused aphasia. Receptive aphasia in which such abilities are preserved is also known as Wernicke's aphasia. In this condition there is a major impairment of language comprehension, while speech retains a natural-sounding rhythm and a relatively normal syntax.

Other causes of Wernicke's Aphasia include brain trauma, cerebral tumors, central nervous system (CNS) infections, and degenerative brain disorders. [ 14 ] In the case of brain tumors, infections, or degenerative brain disorders, examples in which damage to the brain can be ongoingly progressive, it is likely that the aphasia will coincidingly ...
The location of the brain lesion and type of the aphasia can then be inferred from the observed symptoms. The Minnesota Test for Differential Diagnosis is the most lengthy and thorough assessment of sensory aphasia. It pinpoints weaknesses in the auditory and visual senses, as well as reading comprehension.

Global aphasia typically results from an occlusion to the trunk of the middle cerebral artery (MCA), [2] which affects a large portion of the perisylvian region of the left cortex. [7] Global aphasia is usually a result of a thrombotic stroke, which occurs when a blood clot forms in the brain's blood vessels.
