Q

Key features of Broca’s

A

1.Agrammatism: grammar reduced to simplest forms, limited speech output; omitted yet obligatory parts of speech
2. awkward, effortful articulation
3. Relatively intact A/C, R/C
Generally good awareness/comprehension
4. Somewhat reduced prosody/melody

Global aphsia is severaly impaired in all language modalities

A

AC, RC,
OE, & WE
-Likely nonverbal

Q

Transcortical Motor characteristics

A

REPETITION INTACT!! (so… fluent repetition?)
Impaired spontaneous speech
-Can’t produce own, but can repeat others language…..
-Limited organization & initiation of own speech, -language
Could provide one-word responses (yes, no)
-Otherwise, much like Broca’s
R hemiparesis
Paucity, slowness of moveents

Q

Transcoritcal Motor SOL

A 
more varied, smaller
Outside of Broca’s area!!!
Just anterior to Broca’s,
And/or deep to Broca’s 
May involve supplemental motor areas anterior to 1* motor strip

Q

Transcortical motor aphasia- lesions seperate premotr cortex from Broca’s so…

A

Cannot plan/sequence their own intended language-sentence. But, can repeat someone else’s sequenced phonemes/intended sentence

Q

Transcortical output and syntax

A

agrammatic speech~syntax errors

paraphrasic errors~literal and verbal

19
Q

SOL of wenicke’s aphasia

A

posterior, superior L temporal, auditory association, & surrounding parietal regions
May also involve medial temporal lobe
Angular gyrus

20
Q

Blood supply for Wernicke’s

A

L MCA, inferior division

21
Q

Wernickes issues

A
  • Lack of awareness huge problem
  • No apparent physical issues!! (no hemi)
  • Minimal frustration, sound confused
  • May become depressed, isolated, paranoid
22
Q

Wernicke’s clinical rundown

A

ORAL EXPRESSION- fleunt- sterotypicSYNTAX-paragrammatic- neologisitc~SEMANTICS-nonpropositonal, mosltly propostional- paraphsic errors (unintentional)

23
Q

Wernicke’s output and grammar

A

paraphsic speech~literal, verbal and/or neologistic jargonistic
-intact grammar- mixture of intact and innacuate, variety of syntax

24
Q

SOL for transcorical sensory aphasia

A

posterior temporoparietal region (supramarginal, angular)

Spares Wernicke’s area & arcuate fasciculus

25
Q

Allows brain to auditorily interpret SOMEONE ELSE’S spoken input and send forward to Broca’s for speech repetition! BUT

A

But lesions to association areas prevent Wernicke’s from accessing semantic knowledge or experience or other associational input

26
Q

Transcortical sensory aphasia output and grammar

A
  • full of paraphasia-semantic and neologistic
  • naming severely impaired
  • meaningless speech-intact reptition
27
Q

SOL for conduction

A
  • Arcuate fasciculus, (circuit between Broca’s and Wernicke’s, even though B & W are intact)
  • Anywhere along these fibers… more anterior makes it less fluent; more posterior makes it more fluent
28
Q

In conduction aphasia repitition is disproportionally impaired to

A

spontaneous speech. PRimary feature– CANNOT REPEAT

29
Q

Receptive skills for conduction

A

AC is near normal
May comprehend what they struggle to repeat
RC generally not significantly impaired

30
Q

Conduction Aphasia disrupted repetition

A

Paraphasic—literal
Becomes worse as length increases
Becomes worse as familiarity decreases
More difficult to repeat functor words

31
Q

Describe conduction aphasia in terms of syntax

A

paragrammatic- order of words, misappropriation of syntactical structures. Syntax might not be bad

32
Q

Describe conduction aphasia in terms of semantics

A

paraphasic- verbal (might be related word), neologistic

33
Q

Main problem in conduction aphasia

A

Repetition disproportionately impaired to spontaneous speech!!!

34
Q

Conduction- AC? RC?

A

-AC is near normal
May comprehend what they struggle to repeat
-RC generally not significantly impaired

35
Q

Anomic aphasia main problem

A

Main problem here is word-retrieval!!!!

36
Q

Anomia is a…

A

symptom

37
Q

anomic is a…

A

type of aphasia

38
Q

Anomic aphasia SOL

A
  • Temporal-parietal, generally
  • May extend into angular gyrus (WE, RC)
  • Least SOL-based of all aphasias
39
Q

Anomic fluent?

A

yes-lengthy runs of speech, variety of syntax, not effortful, prosody and melody.

40
Q

anomic syntax?

A

relatively intact, good. Not use paragramtic (most fluents are paragramtic)

41
Q

Anomic AC? RC?

A 
-AC relatively preserved
But may fail to discern qualitative difference between words
-RC may vary
Could be fine
Could be severe
42
Q

Anomic- OE?

A 
Fluent
Good repetition!!
Grammatic!!
Word-finding errors
     No paraphasias
     Yet “empty” speech
      Circumlocutions
Deliberately try to explain thing
Vague quality
43
Q

Anomic WE

A

may vary- fine to severe
