Other Aphasia Types

Question 1

Mixed Nonfluent Aphasia - AC?

Answer 1

Poor AC
Not good enough to be Broca’s
But better than Global

Question 2

Mixed Non fluent Aphasia - RC?

Answer 2

Mild RC deficits

Question 3

Mixed Nonfluent Aphasia expressive

Answer 3

Like Broca’s
Agrammatic
Mod repetition deficits
Decreased speech initiation
Awkward articulation
Effortful articulation
Motor planning, programming

Question 4

Mixed Nonfluent Aphasia word finding deficits?

Answer 4

yes-substantives, pictures, action words

Question 5

Subcortical aphasias

Answer 5

Acquired language disorders d/t brain damage in subcortical, white matter structures and/or subcortical grey matter

Question 6

What aphasia is INDIRECT consequence of disruption in this transfer/editing/processing system

Answer 6

subcortical aphasias

Question 7

SOL for subcortical (thalamic) aphasias

Answer 7

Thalamic nuclei
BG
Internal Capsule
White matter/periventricular areas…?

Question 8

What is the thalamus involved in?

Answer 8

• is a sensory-relay station -receives input from peripheral sensory receptors
• sends sensory stimuli to cortical structures for perception and process
• involved in motor processes,
• relays motor input from cerebellum to motor cortex

Question 9

What happens if a lesion occurs in the thalamus

Answer 9

can’t relay sensory feedback from periphery, or transport motor info to and from the cerebellum.

Question 10

Thalamic (subcortical) aphasia receptive skills

Answer 10

Typically Good AC

MAY be mod impaired

Question 11

Thalamic (subcortical) aphasia expressive

Answer 11

-Anomia is hallmark
Cant access words
Confrontation naming deficits
Rare paraphasias
-Excellent repetition
-Good syntax & artic
-Just can’t access lexicon

Question 12

Subcortical aphasias associated w/ lesions in BG

Answer 12

Relatively few studies characterizing subcortical aphasias due to lesions in the BG
“worse” if cortical lesion AND a subcortical BG lesion?

Question 13

Subcortical Aphasias associated w/lesions in BG

Answer 13

Has some type of role in automatized speech and language?
Motor? Slow, nonfluent, effortful
Yet also cases of impaired comprehension
“Mixed” ?
With some features of confused/mis-used grammar
“Fluent”?

Question 14

BG what do they do?

Answer 14

Modulates, regulates, refines voluntary motor movements

Question 15

Internal capsule (subcortical) aphasia is

Answer 15

2-way hi-way connecting cortex to brainstem (BS) spinal cord (SC)

Question 16

Internal Capsule (Subcortical) Aphasia- aphasic characterisitcs

Answer 16

Anterior IC lesions = non-fluent

Posterior IC lesions = fluent

Question 17

Bi/Multilingual Aphasia

Answer 17

You can be aphasic in one or both languages
Are some cases of being aphasic in L1 today, and aphasic in L2 tomorrow
There is a diversity of patient-presentation:
Levels of severity & patterns of recovery between each language

Question 18

Bi/multi-lingual aphasia involves different SOLs:

Answer 18

EFs (PFC, FL, & extensions…)
Attention, inhibition, working memory
Self-monitoring components of EFs
Might be “aphasic” due to atypical SOLs (PFC, FL), rather than “expected” SOLs of language circuits
