Definitions for "Broca's aphasia"
(Synonyms: anterior, expressive, or nonfluent aphasia). A primary deficit in language output (production), in which comprehension is largely unaffected. The defect may involve loss of all propositional speech, or the patient may use a small number of substantive words which are laboriously enunciated and not combined into grammatical phrases. The patient can repeat words, but the repetition has the same abnormalities as the individuals' own speech. The impairment in writing is usually equally severe. The patient is almost always aware of the problem. In right-handers, the lesion is in the left inferior frontal lobe; often there is accompanying paralysis of the lower face or arm on the right side.
A disturbance of speech or reading caused by a defect in the motor (afferent or affector) apparatus of the brain. Comprehension of speech is usually not affected.
Loss of the ability to comprehend language coupled with production of inappropriate language.
