A typical patient with Broca's aphasia will misinterpret "the man is bitten by the dog" by switching the subject and object to "the dog is bitten by the man." This is exemplified by the difficulty to understand phrases or sentences with unusual structure. Because comprehension is substantially impaired for more complex sentences, it is better to use simple language when speaking with an individual with expressive aphasia. Individuals with Broca's aphasia understand most of the everyday conversation around them, but higher-level deficits in receptive language can occur. In general, word comprehension is preserved, allowing patients to have functional receptive language skills. They are usually aware of their communication deficits, and are more prone to depression and outbursts from frustration than are patients with other forms of aphasia. ![]() Self-monitoring is typically well preserved in patients with Broca's aphasia. For example, a person with expressive aphasia might say "Smart. A communication partner of a person with aphasia may say that the person's speech sounds telegraphic due to poor sentence construction and disjointed words. The omission of function words makes the person's speech agrammatic. However, function words like conjunctions, articles, and prepositions are rarely used except for "and" which is prevalent in the speech of most patients with aphasia. The speech of a person with expressive aphasia contains mostly content words such as nouns, verbs, and some adjectives. įor example, in the following passage, a patient with Broca's aphasia is trying to explain how he came to the hospital for dental surgery: Intonation and stress patterns are also deficient. The prosody of a person with Broca's aphasia is compromised by shortened length of utterances and the presence of self-repairs and disfluencies. Long pauses between words are common and multi-syllabic words may be produced one syllable at a time with pauses between each syllable. Individuals with expressive aphasia may only produce single words, or words in groups of two or three. Misarticulations or distortions of consonants and vowels, namely phonetic dissolution, are common. īroca's (expressive) aphasia is a type of non-fluent aphasia in which an individual's speech is halting and effortful. Expressive aphasia also differs from apraxia of speech, which is a motor disorder characterized by an inability to create and sequence motor plans for speech. Expressive aphasia differs from dysarthria, which is typified by a patient's inability to properly move the muscles of the tongue and mouth to produce speech. Expressive aphasia contrasts with receptive aphasia, in which patients are able to speak in grammatical sentences that lack semantic significance and generally also have trouble with comprehension. It is one subset of a larger family of disorders known collectively as aphasia. It is caused by acquired damage to the anterior regions of the brain, such as Broca's area. Typically, comprehension is mildly to moderately impaired in expressive aphasia due to difficulty understanding complex grammar. In very severe forms of expressive aphasia, a person may only speak using single word utterances. The person's intended message may still be understood, but their sentence will not be grammatically correct. Speech generally includes important content words but leaves out function words that have more grammatical significance than physical meaning, such as prepositions and articles. A person with expressive aphasia will exhibit effortful speech. ![]() Broca's aphasia, non-fluent aphasia, agrammatic aphasiaīroca and Wernicke are two areas involved in language formationĮxpressive aphasia, also known as Broca's aphasia, is a type of aphasia characterized by partial loss of the ability to produce language ( spoken, manual, or written), although comprehension generally remains intact. ![]()
