Aphasia Flashcards
(31 cards)
What is aphasia?
Without language
Acquired language disorder caused by disturbance in the language system after language has been established
Results from localized brain damage
Stroke leading cause
Includes deficits in spoken and written language
Aphasia Considerations
NOT:
A developmental disorder
Psychological problem
Motor speech disorder
Intellectual impairment
IS:
A language disorder
How is aphasia classified?
Site of lesion
Behavioral symptoms:
Fluency
Motor output
Comprehension
Repetition
Reading and writing
Naming
Fluency
Qualitative aspect of communication and speech used to describe its forward flow, including phrasing, intonation and rate
Fluent speech:
May include jargon, neologisms, circumlocution and logorrhea.
Nonfluent speech:
Short, choppy phrases with telegraphic quality missing morphemes and other grammatical omissions and errors. Slow and labored speech
Motor output
May be compromised after stroke and co-occur with aphasia
Comprehension
Ability to understand spoken language
Most experience some degree of comprehension deficit
Repetition
Ability to repeat verbal stimuli major factor in differentiating among aphasia syndromes
Naming
Word retrieval, anomia, paraphasia, jargon and neologisms
Reading and writing
Deficits often parallel to verbal language deficits
Concomitant deficits to aphasia: Physical
Hemiparesis: Weakness on one side of body where contralateral hemisphere is damaged
Dysphagia: Paresis/paralysis and sensory impairment involving neck and face may lead to difficulty chewing and swallowing
Anomia
Difficulty naming entities
Incorrect response may continually be produced even if they recognize that it’s incorrect
Jargon
Meaningless/irrelevant speech with typical intonation rate and patterns of language
Strong flow, syntactically correct and rich but makes no sense
Neologisms
Making up a new word and using it confidently; may not be aware that they aren’t saying what they are thinking
May be included in jargon
Paraphasia
Saying the wrong word
Phonemic paraphasia: Saying a different word that sounds phonetically similar (i.e. paint for pasta)
Semantic paraphasia:
Saying a different word in same semantic category (i.e. chicken for pasta)
Circumlocution
Using unnecessarily large number of words to express an idea followed by anomia and word finding difficulties
Logorrhea
Excessive, verbose talkativeness leading to jargon
Aphasia syndromes
Wernickes
Anomic
Conduction
Transcortical sensory
Broca’s
Transcortical motor
Mixed transcortical
Global
Wernickes aphasia
Fluent, no comprehension, no repetition
Characteristics:
Rapid-fire strings of sentences with little pause. Filled with jargon, neologism, logorrhea.
Lesion: Superior and posterior temporal lobe of dominant hemisphere
Anomic aphasia
Fluent, comprehends, repeats
Characteristics:
Anomia naming difficulty most difficult with few deficits in other modalities.
Conduction aphasia
Fluent, comprehends, no repetition
Characteristics:
Paraphasia
Hallmark repetition difficulty with mild to moderate anomia
Lesion: Temporal-parietal region of brain, arcuate fasciculus
Transcortical sensory aphasia
Fluent, no comprehension, repetition
Characteristics:
Strong repetition leading to echolalia
Lesion: Border of temporal and occipital lobe
Broca’s aphasia
Not fluent, comprehends, no repeat
Characteristics:
Short sentences, labored speech, low repetition.
Lesion: Anterior frontal lobe of broca’s area of language dominant hemisphere
Transcortical motor aphasia
Not fluent, comprehends, repeats
Characteristics:
Difficulty initiating speech and writing, better repetition than spontaneous speech
Lesion:
Frontal lone
Mixed transcortical aphasia
No fluent, no comprehend, repeats
