Question | Answer |
---|---|
Aphasia: | acquired neurological impairment of processing for receptive and/or expressive language. Result of brain injury, head trauma, CVA, tumor or infection. |
Diagnosis of aphasia | based on the site of lesion in the brain and the blood vessels involved. Patients with aphasia are classified based on observation of fluent or non-fluent aphasia. |
Prognosis of aphasia | dependent on the individual patient, location, and extent of the lesion. |
characteristics associated with aphasia with a poor prognosis: | perseveration of speech, severe auditory comprehension impairments, unreliable yes/no answers, and the use of empty speech without recognition of impairments. |
Fluent Aphasia Common lesions: | temporal and parietal lobes of the dominant hemisphere |
fluent aphasia Word output and speech production: | are functional |
fluent aphasia Prosody | is acceptable, but empty speech/jargon |
fluent aphasia Speech: | lacks any substance, use of paraphasias |
Types of Fluent Aphasia: | Conduction Aphasia, Wernicke's Aphasia |
Wernicke's Aphasia Lesion: | posterior region of superior temporal gyrus, Also known as “receptive aphasia” |
Wernicke's Aphasia Comprehension (reading/auditory) is : | impaired |
Wernicke's Aphasia | Good articulation, use of paraphasias |
Wernicke's Aphasia | Impaired writing |
Wernicke's Aphasia | Poor naming ability |
Conduction Aphasia Lesion: | supramarginal gyrus, arcuate fasciculus, Severe impairment with repetition |
Conduction Aphasia , | Intact fluency |
Conduction Aphasia | good comprehension |
Conduction Aphasia Speech: | interrupted by word-finding difficulties |
Conduction Aphasia reading/ writing: | Reading intact, writing impaired |
Non-Fluent Aphasia Common lesions: | frontal lobe of the dominant hemisphere. Poor word output and dysprosodic speech |
Non-Fluent Aphasia | dysprosodic speech |
Non-Fluent Aphasia | Poor articulation and increased effort for speech |
Non-Fluent Aphasia Content: | is present, but impaired syntactical words |
Types of Non-Fluent Aphasia | Broca's Aphasia Global Aphasia |
Broca's Aphasia Lesion: | 3rd convolution of frontal lobe |
Broca's Aphasia | Also known as “expressive aphasia” |
Broca's Aphasia | Most common form of aphasia |
Broca's Aphasia | Intact auditory and reading comprehension |
Broca's Aphasia | Impaired repetition and naming skills |
Broca's Aphasia | Frustration with language skill errors |
Global Aphasia Lesion: | frontal, temporal, parietal lobes |
Global Aphasia Comprehension (reading/auditory) | is severely impaired |
Global Aphasia | Impaired naming, writing, repetition skills |
Global Aphasia | May involuntarily verbalize; usually without correct context |
Global Aphasia | May use nonverbal skills for communication |
