Expressive aphasia (also known as Broca's aphasia) is a type of aphasia characterized by partial loss of the ability to produce language (spoken, manual, [ 1 ] or written), although comprehension generally remains intact. [ 2 ] A person with expressive aphasia will exhibit effortful speech. Speech generally includes important content words but ...
In aphasia (sometimes called dysphasia), [a] a person may be unable to comprehend or unable to 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 the Global North. [3]
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] Acquired impairments of communicative abilities are present across all language modalities ...
The Pennsylvania State University. Cynthia K. Thompson is a neurolinguist and cognitive neuroscientist most known for her research on the brain and language processing and the neurobiology of language recovery in people with aphasia. She served as a member of the faculty at Northwestern University (NU) for 30 years as a Distinguished Ralph and ...
Neuroscience of multilingualism is the study of multilingualism within the field of neurology.These studies include the representation of different language systems in the brain, the effects of multilingualism on the brain's structural plasticity, aphasia in multilingual individuals, and bimodal bilinguals (people who can speak one sign language and one oral language).
Receptive aphasia. Wernicke's aphasia, also known as receptive aphasia, [1] sensory aphasia, fluent aphasia, or posterior aphasia, is a type of aphasia in which individuals have difficulty understanding written and spoken language. [2] Patients with Wernicke's aphasia demonstrate fluent speech, which is characterized by typical speech rate ...
Aphasiology is the study of language impairment usually resulting from brain damage, due to neurovascular accident—hemorrhage, stroke—or associated with a variety of neurodegenerative diseases, including different types of dementia. These specific language deficits, termed aphasias, may be defined as impairments of language production or ...
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.
