(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.
A type of aphasia characterised by loss of ability to produce but not to comprehend speech, associated with injury to Broca's area in the front left hemisphere of the brain (left frontal lobe)
aphasia in which expression by speech or writing is severely impaired
Anterior, non-fluent, or motor aphasia resulting from damage to the anterior portion of the language dominant cerebral hemisphere: specifically the posterior-inferior portions of the frontal lobe (inferior frontal gyrus); spoken output labelled “telegraphic” and characterized primarily by content words (e.g., nouns, adjectives) and few connector words (e.g., pronouns, articles “the” and “a”, and auxiliary verbs, etc.); listening and reading comprehension better preserved; motor programming problems (apraxia of speech) and limb motor strength difficulties (paralysis or paresis) frequently co-occur.
The partial or complete inability to produce spoken language and use certain grammatical rules, due to damage in the Broca's Area of the brain.
A form of nonfluent aphasia characterised by slow and ‘telegrammatic' speech, where key words are spoken, often in the wrong order, but the words that would usually link them into a sentence or phrase are missing. It is named after the French neurologist, Broca, who first associated this form of aphasia with damage to the left, frontal area of the brain.
an acquired language disorder due to damage in Broca's area and characterized by non-fluent, effortful speech
characterized by nonfluent speech, decreased verbal output, effortful speech, poor grammatical form, poor naming, poor reading, poor writing, can understand better than they can speak; person is usually frustrated because they are aware what they say is not making sense
Aphasia caused by damage to the motor speech area ( Ch. 27).
An infarct to a specific area of the frontal lobe that produces the inability to verbally communicate. Speech is difficult, but comprehension is usually functional or normal
