Aphasia Part 2 Flashcards
pure word deafness
- loss of ability to understand spoken speech
- written comprehension intact, intact written/verbal production
pure word deafness: behavior and anatomy dissociate from…
Wernicke’s aphasia
subcortical aphasia: lesions
- internal capsule and putamen
- anterior limb of the internal capsule and putamen
- left posterior internal capsule/putamen
- left anterior/posterior internal capsule, putamen, and thalamic
subcortical aphasia: lesions in internal capsule and putamen
aphasia shared features of both Broca’s and Wernicke’s, but did not completely resemble either
subcortical aphasia: lesions in the anterior limb of the internal capsule and putamen
- severe impaired dysarthric speech
- adequate phrase length (4-6 words)
- mild word repetition deficit
- mild to moderate anomia
- mild auditory comprehension deficit
- mild to moderate reading problems
- marked to severe writing deficit
- persisting right hemiplegia
subcortical aphasia: left posterior internal capsule/putamen lesions
- fluent speech
- adequate phrase length
- intact syntax
- mild or no articulatory problems
- severe auditory comprehension problems
- severe anomia
- repetition errors in sentences more than single words
- reading/writing moderately impaired
subcortical aphasia: left anterior/posterior internal capsule, putamen, and thalamic lesions
- global aphasia
- spontaneous speech limited to sterotypic monosyllables
- phrase length of one word
- severe dysarthria
- no evidence of syntax
- auditory comprehension, naming, reading, and writing severely impaired
- persisting right hemiplegia
subcortical aphasia: related disorders
- perseveration
- motor speech disorders
- hemiplegia
- impaired sensory motor efficiency
- emotional lability/catastrophic response
- visual field blindness
- visual agnosias
perseveration
continuation of an activity beyond where it is appropriate
motor speech disorders
- dysarthria
- apraxia of speech
hemiplegia
right paresis/paralysis
visual field blindness
- right homonymous hemianopsia
- patient unable to see to the right of midline
- most associated with posterior lesions
visual agnosias
- visual object, color, prosopagnosia
- agnosia
prosopagnosia
inability to identify faces
agnosia
inability to identify something
visual field blindness: related disorders
- auditory agnosias
- tactile agnosias
- modification of pre-morbid personality
- difficulty dealing with the abstract
- short attention span
- reduced intellectual functioning
- mild memory retention deficits
- increased ego-centricity
- need for order
- fatigue easily
- incontinence
- seizures
- breathing difficulties
- dysphagia
auditory agnosia
good with nonspeech sounds, difficulty with words
difficulty dealing with the abstract
figurative language, sarcasm
short attention span
alternating, sustained, divided, joint, selective
mild memory retention deficits
recall strategies
increased ego-centricity
difficulty putting themselves into someone else’s shoes
