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 ...
Patients with expressive aphasia may be able to speak in short or very short sentences. ... "Aphasia resulting from acquired brain injury will be diagnosed by a speech-language pathologist or ...
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 ...
Aphasia is a disorder of impaired language production and understanding, but does not impact general cognitive abilities or intelligence. Aphasia is a serious, disruptive disorder, but there is ...
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]
Broca's aphasia is a specific type of expressive aphasia and is so named due to the aphasia that results from damage or lesions to the Broca's area of the brain, that exists most commonly in the left inferior frontal hemisphere. Thus, the aphasia that develops from the lack of functioning of the Broca's area is an expressive and non-fluent aphasia.
