Aphasias & Brain Lesions Flashcards
(26 cards)
A patient presents with sentences that make no sense, word substitution and neologisms but speech remains fluent.
What type of aphasia is this? [1]
Where is the lesion occurring? [1]
Wernicke’s (receptive) aphasia
- lesion of the superior temporal gyrus
Wernicke’s (receptive) aphasia is normally supplied by which artery? [1]
inferior division of the left MCA
Where is Broca’s aphasia occuring? [1]
Due to a lesion of the inferior frontal gyrus
Broca’s aphasia is due to a lesion of the inferior frontal gyrus. It is typically supplied by the [1]

A. Broca’s aphasia
B. Wernicke’s aphasia

Temporal lobe
A patient is noted to have no speech and appears to understand little of what is said to him - global aphasia
Dysarthria
A patient is noted to speak fluently but makes little sense with mulitple word substitutions and neologisms. He also has difficulty understanding what people are saying to him - Wernicke’s aphasia
