A Case of the Fluent Form of Primary Progressive Aphasia Presenting as Conduction Aphasia

ABSTRACT

Primary progressive aphasia(PPA) can be classified into nonfluent and fluent types. The fluent PPA usually manifests as Wernicke's or transcortical sensory aphasia. We report a 61-year-old right-handed woman who presented with a fluent PPA. An aphasia test revealed fluent speech and intact comprehension but decreased repetition and naming, consistent with conduction aphasia. Other cognitive functions and activities of daily living were preserved. Brain MRI and SPECT respectively showed a focal atrophy and a hypoperfusion in the left temporal lobe.
