Fluent aphasias Flashcards
fluent speech
- relatively well-preserved fluency
- speech is abundant (are talking and using long sentences)
- verbal output in the range of 100-200 words per minute
- normal phrase length of 5 to 8 words
- no trouble with grammar
- precise articulation
- normal prosody
- normal auditory comprehension
- meaningless words
What are the fluent aphasias?
- Wernicke’s
- conduction
- anomic
- transcortical sensory
a lesion to where causes wernicke’s aphasia?
usually left posterior, temporal - often extending up into parietal lobe
Wernicke’s aphasia auditory comprehension:
impaired/poor
Wernicke’s aphasia
- impaired repetition skills
- naming and repetition impaired
- poor word finding/word retrieval (“empty speech)
- speech may be filled up with general words
Wernicke’s aphasia
- fluent speech (little meaning conveyed)
- paraphasias (verbal/non-semantic, semantic, phonemic/literal)
- neologistic jargon
- relative lack of awareness of errors
logorrhea or press of speech - normal prosodic and generally intact grammatical forms
- impaired reading comprehension and writing skills
- perseverations
Wernicke’s aphasia
- normal articulation (no AOS present)
- turn taking problems
- difficulty maintaining topic
- lack of insight into their disability (not fully aware)
- lack of frustration in failed to communicate
- not hemiplegic
a lesion to where causes conduction aphasia?
lesion to lower parietal lobe, involves arcuate fasciculus, supramarginal gyrus, or small part of wernicke’s area
what is the hallmark of conduction aphasia?
the inability to repeat or imitate speech
conduction aphasia auditory comprehension
impaired, but often only mildly
Conduction aphasia characteristics
- better recognition of errors/better self-monitoring (self-corrections)
- word finding/naming problems
- paraphasias (phonemic, semantic and verbal), neologisms (less frequent/rare)
- good phrase length, syntax and prosody of language
- variable reading and writing problems
a lesion to where causes anomic aphasia?
lesion to angular gyrus area or lower temporal lobe
characteristics of anomic aphasia
- word retrieval problems during spontaneous speech
- difficulty naming when asked to name pictures or objects
anomic aphasia auditory comprehension
better auditory comprehension, good
anomic aphasia characteristics
- thought formulation difficulties
- repetition is usually intact or just mildly impaired
- syntax is OK and normal articulation
- normal or near normal oral reading and writing
- paraphasias (verbal)
