5

Broca's clincial rundown

grammar-sterotypic~nonpropostional

6

Key features of Broca's

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

7

Additional diagnoses often associated with Broca's aphasia

1.Apraxia (motor planning, programming, intiation)
2. R hemiplegia (paralysis) hand, arm, leg
3.R hemiparesis (weakness) hand, arm, leg, face
4.Dysarthria (weakness)

8

Artery that supplies Brocas

left middle cerebral artery, superior branch

9

Broca's aphasia additional SOL

White matter deep to Broca's. Superior longitudinal fasciculus (dorsal) . Extreme capsule (ventral)

10

Broca's clinical rundown two

ORAL EXPRESSION-->nonfleunt--SYNTAX-- agrammatic--OUTPUT-- telegraphic
SEMANTICS- severe anomia (not retrieving words)

11

Global aphsia is severaly impaired in all language modalities

AC, RC,
OE, & WE
-Likely nonverbal
-Alert & aware, can recognize people, places
-May gesture, use facial expression, point
-Cannot communicate through symbolic language

12

SOL of Global

entire perisylvian region

13

Blood Supply of Global aphasia

Blood supply from both major branches of MCA
-Damage to BOTH anterior and posterior language regions

14

Transcortical Motor characteristics

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

15

Transcoritcal Motor SOL

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

16

Blood supply to Transcortical Motor

ACA, and anterior branch of MCA

17

Transcortical motor aphasia- lesions seperate premotr cortex from Broca's so...

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

18

Transcortical output and syntax

agrammatic speech~syntax errors
paraphrasic errors~literal and verbal

19

SOL of wenicke's aphasia

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

20

Blood supply for Wernicke's

L MCA, inferior division

21

Wernickes issues

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

22

Wernicke's clinical rundown

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

23

Wernicke's output and grammar

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

24

SOL for transcorical sensory aphasia

posterior temporoparietal region (supramarginal, angular)
Spares Wernicke’s area & arcuate fasciculus

25

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

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

26

Transcortical sensory aphasia output and grammar

-full of paraphasia-semantic and neologistic
-naming severely impaired
-meaningless speech-intact reptition

27

SOL for conduction

-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

In conduction aphasia repitition is disproportionally impaired to

spontaneous speech. PRimary feature-- CANNOT REPEAT

29

Receptive skills for conduction

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

30

Conduction Aphasia disrupted repetition

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

31

Describe conduction aphasia in terms of syntax

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

32

Describe conduction aphasia in terms of semantics

paraphasic- verbal (might be related word), neologistic

33

Main problem in conduction aphasia

Repetition disproportionately impaired to spontaneous speech!!!

34

Conduction- AC? RC?

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

35

Anomic aphasia main problem

Main problem here is word-retrieval!!!!

36

Anomia is a...

symptom

37

anomic is a...

type of aphasia

38

Anomic aphasia SOL

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

39

Anomic fluent?

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

40

anomic syntax?

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

41

Anomic AC? RC?

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

42

Anomic- OE?

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

43

Anomic WE

may vary- fine to severe
