Communication Disorders Flashcards
1
Q
Basis for diagnosis of Aphasias
A
- Site of lesion in the brain
- Blood vessels involved
2
Q
Affected areas for Fluent Aphasia
A
- Temporal Lobe
- Wernicke’s Area
- Regions of Parietal Lobe
3
Q
Types of Fluent Aphasia
A
- Wernicke’s Aphasia
- Conduction Aphasia
4
Q
Wernicke’s Aphasia Characteristics
A
- aka “receptive aphasia” (impaired comprehension)
- Lesion: posterior region of superior temporal gyrus
- articulation unimpaired
- Impaired writing
- Poor naming ability
5
Q
Conduction Aphasia Characteristics
A
- Lesion: supramarginal gyrus, arcuate fasciculus
- Severe impairment with repetition
- Good comprehension
- Word-finding difficulties
- Reading intact, writing impaired
6
Q
Brain Areas affected with Non-Fluent Aphasia
A
-frontal lobe of the dominant hemisphere (anterior speech center)
7
Q
Characteristics of non-fluent aphasia
A
- poor word output; impairment in rhythm and inflection
- poor articulation
- increased effort for speech
8
Q
Types of Non-fluent Aphasia
A
- Broca’s Aphasia
- Global Aphasia
9
Q
Broca’s Aphasia Characteristics
A
- Lesion: 3rd Convultion of Frontal Lobe
- “Expressive aphasia” (Broca = boca)
- Reading/comprehension intact
- Impaired repetition/naming skills
- Frustration
- Motor impairment typical due to proximity of broca’s area to motor cortex
10
Q
Most Common form of aphasia
A
Broca’s Aphasia
11
Q
Global Aphasia Characteristics
A
- Lesion: frontal, temporal, parietal lobes
- Comprehension and expression severely impaired
- May use nonverbal skills for communication
12
Q
Verbal Apraxia
A
- Understands verbal expression but unable to initiate due to poor motor planning
- Lesion: left frontal lobe adjacent to Broca’s area
13
Q
Dysarthria
A
- UMN lesion causing weakness of muscles used to speak
- Speech often “slurred”
