associative aphasia
Definition
Noun: * A type of language disorder: A specific form of aphasia where the primary symptom is a severe inability to repeat words or sentences that have just been heard, while other language functions like spontaneous speech and comprehension may be relatively preserved. It is theorized to result from damage to the neural pathways (association tracts) that connect different language-processing areas of the brain.
Examples of Usage
- The neurologist diagnosed the patient with associative aphasia after noting their profound repetition deficit.
- A key characteristic of associative aphasia is the dissociation between impaired repetition and relatively fluent spontaneous speech.
- The study focused on rehabilitation strategies for individuals suffering from associative aphasia.
Advanced Usage
- In clinical neuropsychology, associative aphasia is often discussed in contrast to other aphasia types, such as Broca's or Wernicke's aphasia, based on the pattern of language deficits.
- The term is sometimes used synonymously with conduction aphasia in some classification systems, though theoretical models of the underlying neurological cause may differ.
Variants and Related Words
- Aphasia (n): The broader category of language impairment caused by brain damage.
- Conduction aphasia (n): A frequently used near-synonym for associative aphasia, emphasizing the disruption in communication between brain regions.
- Disconnection syndrome (n): A theoretical framework in which associative aphasia is considered a classic example, where functions are lost not because a specific center is damaged, but because the connections between centers are severed.
Synonyms
- Conduction aphasia
- Repetition aphasia (descriptive synonym)
Related Phrases
- Repetition deficit: The core symptom of associative aphasia.
- Disconnection hypothesis: The theoretical explanation for the cause of associative aphasia.
Noun
