aphasia Flashcards
(17 cards)
categories of aphasia
nonfluent
fluent
subcortical
characteristics of nonfluent
limited agrammatic effortful halting slow speech impaired prosody
types of nonfluent
broca’s
global
transcortical motor
mixed transcortical
what is fluent aphasia
fluency is intact, less meaningful speech; usually good flow, articulation, and prosody
types of fluent aphasia
wernickes
conductive
anomic
transcortical sensory
where is brocas aphasia and wernickes aphasia
both in left hemspiher
lesion to Broca’s area which is in posterior inferior frontal gryrus
lesion to wernickes are in posterior portion of superior temporal gyrus
repetition for broca’s and wernicke’s
both impaired repetition
area of transcortical motor
anterior superior frontal lob of language hemisphere
characteristics of transcortical motor
rigid upper extremities (motor), slow movement or no movement at all, generally good comprehension, good repetition
mixed transcortical aphasia
spares broca’s and wernickes, impairs language association areas; like global but CAN repeat
mixed transcortical aphasia
caused by watershed stroke; spares broca’s and wernickes, impairs language association areas; like global but CAN repeat
global aphasia
most severe
affects comprehension and expression both wernickes and broca’s
impaired repetition
wernicke;s
impaired repletion word finding issues poor comprehension poor self monitoring jargon
transcortical sensory
lesion in temporoparietal lobe, may affect occipital
poor comprehension
good repetition
fluent but empty speech
what is damaged in conduction aphasia
arcuate fasciculus *(temporal, parietal, area 41 and 42 auditory cortex)
characteristics of conductive aphasia
grossly impaired repetition, relatively preserved language comprehension
explain all the aphasias
broca’s- nonfluent; posterior inferior frontal gyrus; poor repetition
transcortical motor- nonfluent; anterior superior frontal lobe in language hemisphere; rigid to little movement; good comprehension, good repetition
mixed transcortical- nonfluent; poor language overall but doesn’t affect broca’s or wernickes, like global but good repetition
global- impaired broca and wernickes
wernicke- fluent; poor comprehension, poor repetition but fluent speech; posterior portion of superior temporal gyrus
conduction- fluent, rare, arculate fasciculus; good comprehension very poor repetition
transcortical sensory- fluent, temporoparietal lesion, poor comprehension good repetition, no meaning in speech
anomic- usually result of aphasias kind of affects all areas
