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]
Conduction aphasia is a mild language disability, and most people return to their normal lives. [11] [14] Broca's and Wernicke's aphasia are commonly caused by middle cerebral artery strokes. [15] Symptoms of conduction aphasia, as with other aphasias, can be transient, sometimes lasting only several hours or a few days.

Global aphasia occurs due to a lesion in the perisylvian cortex, including Broca's and Wernike's areas. [ 1] 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 ...
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 ...
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, intact syntactic ...
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.
