Flashcards in Aphasia Terms Deck (43):
1

word-retrieval deficits with preserved repetition and spontaneous speech

anomia

2

anomia can be a...____ or ____

symptom of aphasia or can be type of aphasia itself

3

typical characteristics of anomis

1.delayed or unable to retrieve words
2.may be specific to certain classes of words
3.may talk around the problem (circumlocution)
4. may substitute general words for a specific thing

4

is anomia a phoneme problem or a semantic, word level problem

it IS a semantic, word-level problem

5

What is paraphasia

production of unintended syllables, words, or phrases during speech.

6

Are paraphasia errors deliberate?

No, substitution errors, not deliberate

7

What type of aphasia usually demonstrates paraphasia

generally found in fluent aphasia

8

3 types of substitutions found in paraphasia

literal, neologistic, and verbal

9

What are literal substitutions

phonemic substitutions, sequential errors (nen for pen, or pet for pen) have a mix fluent or non

10

What are neologisitc substitutions

jargon substitutions (alovit for pen), resulting from severe phonemic substitutions and/or mis-sequencing (Neologisms). Isolated to wernickes or Post or fluent aphasia

11

What are verbal (semantic) substituions

word substitutions (paper for pen); not a circumlocution, which is an intended substitution

12

What is perseverative paraphasia

previous response persists, interferes with retrieval of new response

13

What is stereotypic speech

Oral expression relegated to sub-propositional speech only
i.e. overlearned, rote productions
May be limited to only yes/no, even

14

Agrammatic is usually found in what type of aphasia

non-fleunt oral expression-->brocas

15

Agrammatism is characterized by

Omission of grammatical variety
Omission of functor words (articles, prepositions personal pronouns, verb inflections)
Lack variety, clarity, specificity

16

Examples of description of agrammatic sytntax

likely omitting parts of speech that are obliged to be there, simplifications, not a variety in sentence strucutres

17

Paragrammatism is a descriptor of syntax in

fluent oral expression (typically)

18

Is Paragrammatism is characterized by omission or errors in grammar

errors in grammar

19

Paragrammatism- errors in grammar include

tense markers, misuse of pronouns, confused syntax, and oddly produced sentence forms. Violate grammar and syntax rules

20

What is repetition

“Ability to reproduce, from auditory presentation, patterns of familiar speech sounds”
-Impaired repetition is diagnostically significant
Intact repetition requires whole “circuit”

21

What is oral reading

-Motor speech production of written text
-Ability to phonetically decode written text and
-Ability to motorically produce that code aloud

22

What is reading comprehension

-Understanding the meaning, implications, of written text
-Concrete v. abstract
-Literal v. metaphorical

23

What is alexia

acquired reading disorder; different types

24

Different types of alexia

1. right hemisphere based
2. left hemisphere based- often associated with alexia. Every patient with aphasia will have some degree of alexia

25

Alexia with agraphia (parieto-temporal alexia)

impaired reading and writing

26

Alexia without agraphia (occipital alexia)

Impaired reading, relatively preserved writing

27

Frontal alexia

-Single-word RC for content
-Impaired RC for other parts of speech
-Also impaired writing

28

Written Expression is

Transmission of linguistically organized motor instructions & produced in visual symbol format (not auditory symbol) (G

29

What is agraphia

acquired impairment in written expression. Right or left hemi based. If left, often associated with aphasia

30

Frontal agraphia

Impaired motoric aspects of writing (spelling, formation)

31

Parietal agraphia

Impaired access to, or organization of, graphemes to support meaning

32

Alexic-agraphia

Impaired reading and writing

33

Apraxic-agraphia

Impaired ability to plan/sequence writing movements, even gestures

34

General Category- Nonfluent/anterior. What are the syndromes

Brocas, Transcortical motor, Global, and Transcortical mixed

35

General Category-Fluent/posterior

Wernickes, Conduction, anomic, and transcortical sensory

36

Key symptoms and generally associated site of lesion for Brocas

-agrammatic production
-Broca's and surrounding area

37

Key symptoms and generally associated site of lesion for Transcortical Motor

-agrammatic production~like borca's
-prefrontal cortex of L frontal lobe

38

Key symptoms and generally associated site of lesion for Global

-poor AC, minimal OE
-Posterior & frontal perisylvian language region

39

Key symptoms and generally associated site of lesion for Transcortical mixed

-poor AC, minimal OE~Like Global, but repetition intact
-Diffuse, multifocal damage to frontal, parietal lobes

40

Key symptoms and generally associated site of lesion for Wernicke's

-Poor AC, jargon OE, press for speech
-Wernicke’s area (post part of superior temporal gyrus)

41

Key symptoms and generally associated site of lesion for Conduction

-Severely impaired repetition, otherwise “good” OE
-Association tract beneath posterior temporo-parietal boundary (arcuate fasciculus)

42

Key symptoms and generally associated site of lesion for Anomic

-Word-finding deficits, empty speech
-Angular gyrus (posterior temporo-parietal boundary)

43

Key symptoms and generally associated site of lesion for Transcortical-sensory

-Like Wernicke’s, but repetition intact
-Inferior temporo-occipital border area
