Pure Anomic Aphasia Caused by a Subcortical Hemorrhage in the Left Temporo-parieto-occipital Lobe.

Abstract

There have been few case reports of pure anomic aphasia and the underlying mechanism remains to be clarified. Wereport a patient in whom pure anomic aphasia was caused by subcortical hemorrhage in the left temporo-parieto-occipital lobe. Based on magnetic resonance images and cerebral blood flow imaging, the structural lesion underlying the pure anomic aphasia was thought to be located at the left temporo-occipital junction.

Confrontation naming in Chinese patients with left, right or bilateral brain damage

“…It is well understood from studies of patients with English as their first language that spontaneous speech is primarily mediated by the left hemisphere, especially Broca's area, which is located at the prefrontal region (Brodman's area 44). Thus, impairment on spontaneous naming is commonly observed in patients with left hemisphere damage, especially in (Kohn & Goodglass, 1985;Kreisler et al, 2000) but not limited to (Damasio et al, 1996;Kreisler et al, 2000;Takeda et al, 1999) Broca's area. For example, Damasio et al (1996) reported that lesions in various locations of the left, but not the right, temporal lobe were associated with naming difficulty.…”
