(12 cards)
How can aphasia affect input?
- understanding spoken words and sentences
- understanding written words and sentences

- production of spoken words/sentences
- writing words
Define aphasia
an acquired disorder of language processing subsequent to damage to language centres in brain as result of stroke, head injury, brain tumour, neurosurgery, infections, etc
What are the different classifications of aphasia?
- fluent/non-fluent
- expressive/receptive
-brocas, wernickes, conduction
What are the broad syndromes of aphasia?
- brocas
- wernickes
- anomic
- conduction
- global
Why is it useful to classify aphasia with the syndrome approach?
- can be helpful for individual to know type
- can make predictions on how they will present
- can be a helpful first step
Describe brocas aphasia
- good comprehension of words
- impaired production of words
- impaired repitition
- non-fluent production
- ommision of affixes and grammatical morphemes
- ssentence comp impaired
Describe wernicke’s aphasia
- comp of words/sentences impaired
- impaired production of words
- impaired repitition of words
- fluent speech production
- can lack insight into use of incorrect/irrelevant words
- paragrammatic
Describe conduction aphasia
- good comp words/sentences
- good retreival of words but phonological errors (conduite d’approache)
- impaired repitition
- fluent speech production
Describe anomic aphasia
- good comp of sentences/words
- impaired production of words
- good repitition
- fluent production (may appear non-fluent when WFD)
- frequent WFD in connected speech
Describe global aphasia
- impaired comp of words/sentences
- impaired production of words
- impaired repitition of words
- non-fluent speech production
Describe Wernicke-Lichtheim model
- maps onto anatomical regions and shows syndrome of damaged area
