adult language Flashcards
neurologically based language disorder caused by various types of neuropathies
aphasia
neuropathies that cause aphasia
CVA, tumors, hydrocephalus, hypoxia, anoxia, infections
caused by a block or interrupted blood supply to the brain
ischemic cva
caused by bleeding in the brain due to ruptured blood vessels with hypertension
hemorrhagic
types of nonfluent aphasias
global
broca’s
transcortical motor aphasia
mixed transcortical
site of lesion for global aphasia
Middle Cerebral artery
global aphasia results in
severe verbal expression
speech production and comprehension deficits
minimal to noncommunication
broca’s site of lesion
posterior inferior left frontal lobe
characteristics of broca’s aphasia
verbal expression - decreased length of utterance, nouns and verbs, reduced prosody
auditory comp - relative strength
reading comp - similar to auditory
written expression - predom of content words
broca’s strengths
manage to communicate, relevant responses, aware of speech problems
site of lesion for transcortical motor aphasia
anterior superior left frontal lobe
characteristics of transcortical motor
similar to broca’s but retain ability to repeat
lesion for mixed transcortical
arterial border of the brain; damage spares and isolates broca’s
characteristics of mixed transcortical
limited spontaneous speech
automatic communication
severe echolalia
severely impaired reading, reading comp, and writing
assessment for aphasia
patient interview, chart review
aud comp - point to items, follow commands, y/n
verbal expression - fluent vs nonfluent automatic speech, sentence completion, rep
reading - letter/word/phrase/sentence
written - spelling, grammatical structure
formal aphasia assessment
BDAE
WAB
BASA
types of fluent aphasia
wernickes
transcortical sensory
conduction
anomic
subcortical
wernicke’s lesion
usually the posterior one third of the temporal gyrus
characteristics of wernicke’s aphasia
verbal expression - effortless, prosodic
pressed for speech, poor rep
auditory comp - impaired at the word level
reading comp - deficits at word level
written - mirrors verbal expression
strengths of wernicke’s
comprehension of repetitive and personal information, maintain correct syntax/artic/prosody
transcortical sensory aphasia lesion
temporoparietal region of brain
