DSA 28 Language Disorders Flashcards
why is facial weakness more common in someone who has Broca’s aphasia?
Broca’s area is next to the motor representing the mouth; the next nearest motor cortex is the hand and arm
which hemisphere is mostly affected when Broca’s aphasia is present?
left hemisphere (dominant hemisphere)
is there any body weakness with Wernicke’s aphasia?
no because Wernicke’s area is the temporal lobe, the motor cortex and sensory cortex are not located in this region
what is the major difference in therapy for Wernicke’s aphasia vs. Broca’s aphasia?
speech therapy is beneficial in Broca’s while it is not in Wernicke’s aphasia
how can you differentiate between conduction aphasia vs. Broca’s/Wernicke’s aphasia?
can’t repeat phrases
what is global aphasia?
nonfluent aphasia with impaired comprehension; arcuate fasciculus, Broca’s, and Wernicke’s areas are affected
what are the associated physical findings with someone who has global aphasia?
right hemiparesis and right hemianopsia
where is the lesion for global aphasia?
usually middle cerebral artery
what artery supplies main speech centers?
left MCA
describe clinical presentation of Wernicke’s (receptive) aphasia.
fluent, impaired comprehension/repetition, no weakness
describe clinical presentation of Broca’s (expressive) aphasia.
non-fluent, comprehension intact, impaired repetition, commonly right hemiparesis
where is Broca’s area usually located?
in the left inferior frontal lobe
what is a finding typically associated with Wernicke’s aphasia?
sensory disturbances
describe clinical presentation of conduction (associative) aphasia.
fluent, intact comprehension, poor repetition
what causes conduction aphasia?
damage to the arcuate fasciculus which connects Broca’s and Wernicke’s areas
