Can a person with conduction aphasia repeat sentences?
Conduction aphasia shares with Broca and Wernicke aphasias the inability to repeat sentences, a defective assembly of phonemes, and an impaired naming ability, but it differs from them in the relatively preserved speech production and auditory comprehension.
Why is repetition impaired in conduction aphasia?
The arcuate fasciculus connects these two regions. The classical explanation for conduction aphasia is that damage to the arcuate fasciculus impairs the transmission of information between the Wernicke area and the Broca area. This injury leads to impaired repetition.
What is repetition aphasia?
In aphasia, assessment repetition is a diagnostic tool used to classify aphasia types, determine severity of motor speech disorders (apraxia of speech and dysarthrias), and assess perseveration (abnormal persistence of a previously appropriate response) and echolalia (unnecessary verbal repetition).
What is damaged in conduction aphasia?
Conduction aphasia, also called associative aphasia, is an uncommon form of difficulty in speaking (aphasia). It is caused by damage to the parietal lobe of the brain.
Why is repetition preserved in Transcortical aphasia?
While a relative preservation of repetition in acute transcortical aphasia (TA) has usually been associated with the functional integrity of the speech dominant (left) perisylvian area, recent amytal data (Bando et al., 1986) have suggested a fundamental role of the nondominant (right) hemisphere in language repetition …
Is repetition impaired in Wernicke’s aphasia?
Reading involves the comprehension of written words, and thus reading is also often impaired in Wernicke’s aphasia. As with Broca’s aphasia, repetition is also impaired.
What is called conduction aphasia?
Conduction aphasia is a type of aphasia in which the main impairment is in the inability to repeat words or phrases. Other areas of language are less impaired (or not at all). It is also known as associative aphasia. A person with conduction aphasia can usually read, write, speak, and understand spoken messages.
Is conduction aphasia fluent or Nonfluent?
Fluent aphasia.
| Category | Type |
|---|---|
| Nonfluent | global aphasia |
| Nonfluent | transcortical motor aphasia |
| Fluent | Wernicke’s aphasia |
| Fluent | conduction aphasia |
Can Broca’s aphasia repeat?
The principal difference between transcortical motor aphasia and Broca’s aphasia is in verbal repetition, which is possible in the former and impaired in the latter. Patients with transcortical motor aphasia often have echolalia in the setting of an otherwise nonfluent speech.
Is repetition intact with Broca’s aphasia?
What kind of speech is affected by conduction aphasia?
An acquired language disorder, it is characterised by intact auditory comprehension, coherent (yet paraphasic) speech production, but poor speech repetition. Affected people are fully capable of understanding what they are hearing, but fail to encode phonological information for production.
What do you call repetitive self correction in aphasia?
This repetitive effort to approximate the appropriate word or phrase is known as conduite d’approche. Repetitive self correction is commonly used by Aphasic people of conduction aphasia.
What kind of tests are used to diagnose aphasia?
For example, the Boston Diagnostic Aphasia Examination (BDAE) and the Western Aphasia Battery (WAB) are two commonly used test batteries for diagnosing conduction aphasia. These examinations involve a set of tests, which include asking the person to name pictures, read printed words, count aloud, and repeat words and non-words.
How does conduction aphasia differ from Broca and Wernicke?
Conduction aphasia shares with Broca and Wernicke aphasias the inability to repeat sentences, a defective assembly of phonemes, and an impaired naming ability, but it differs from them in the relatively preserved speech production and auditory comprehension.
