What is the difference btw Broca's and Wernicke's aphasia?
- Broca's = nonfluent speech but good comprehension
- Wernicke's = fluent speech but poor comprehension
In this disorder, the pt can hear speech but can’t interpret it---similar to listening to a foreign language.
What is the difference btw conduction and global aphasia?
- conduction = fluent speech but good comprehension (damage to Arcuate fasciculus)
- global = nonfluent speech AND poor comprehension (Perisylvian region)
This is an acquired disorder of language caused by brain damage.
What is global aphasia?
- the most severe form of aphasia
- destruction of entire perisylvian language zone
- essentially no language
What is amnesia?
an impairment of recent memory, with deficient new learning
What does damage to the Arcuate fasciculus cause?
Wernicke’s area is in the left posterior superior temporal region in the posterior part of Broadmann’s area ____.
Wernicke’s area is involved in ______ (but not _____).
auditory comprehension but not audition
