When you’re asked to localize the lesion in a patient with aphasia, do you suddenly feel speechless?
At a loss for words to categorize the type of aphasia?
Never fear—here is the decision tree for patients w/aphasia and the associated anatomic correlates
Three main questions:
- Fluency? Nonfluency indicates damage to the FRONTAL language regions anterior to the fissure of Rolando
- Comprehension? Impaired comprehension indicates damage to the TEMPOROPARIETAL language regions posterior to the fissure of Rolando
- Repetition? Impaired repetition indicates damage within the core PERISYLVIAN language zone
The answers will lead you both to the type of aphasia and the location of the lesion.
