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 ...
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]
Although expressive aphasia may be caused by brain damage to many regions, it is most commonly associated with the inferior frontal gyrus, a region that overlaps with motor cortex controlling the mouth and tongue, extending into the periventricular white matter. [3] Not surprisingly, this region has come to be known as "Broca's area". However ...

Global aphasia is a type of aphasia that occurs in people where a large portion of the language center of the brain has been damaged and results in deficits in all modalities of language. [12] Broca's aphasia, also referred to as expressive aphasia, is an aphasic syndrome in which there is damage in left hemisphere, specifically in the Broca's ...
In the classical sense, expressive aphasia is the result of injury to Broca's area; it is often the case that lesions in specific brain areas cause specific, dissociable symptoms, [31] although case studies show there is not always a one-to-one mapping between lesion location and aphasic symptoms. [29]
Damage to the inferior left temporal lobe, which is shown in green, is associated with TSA. Transcortical sensory aphasia is caused by lesions in the inferior left temporal lobe of the brain located near Wernicke's area, and is usually due to minor hemorrhage or contusion in the temporal lobe, or infarcts of the left posterior cerebral artery (PCA). [4]
Global aphasia is a severe form of nonfluent aphasia, caused by damage to the left side of the brain, that affects [1] receptive and expressive language skills (needed for both written and oral language) as well as auditory and visual comprehension. [2]
