Symptoms of Wernickes aphasia
What are the clinical features of Wernicke’s aphasia and where is the lesion responsible for it?
Wernicke’s aphasia is characterized by fluent speech, good articulation, good or sometimes exaggerated prosody (the expressivity of language), impaired naming, phonemic and semantic paraphasias, poor auditory and reading comprehension, impaired repetition, and fluent but empty writing.
It is usually caused by damage to the posterior sector of the left auditory association cortex, Brodmann area 22.
Often there is involvement of Brodmann areas 37, 39, and 40, or all three.
