Naming difficulties in alexia with agraphia for kanji after a left posterior inferior temporal lesion. 1994

Department of Neurology, University of Tokyo, School of Medicine, Japan.

The case is described of a patient with alexia and agraphia for kanji, and severe anomia after a subcortical haemorrhage in the left posterior inferior temporal area. Magnetic resonance imaging at four months after onset showed a lesion in the inferior temporal and fusiform gyri, extending from the temporo-occipital junction toward the anterior third of the temporal lobe. Comparison with other reported cases of alexia with agraphia and anomia made it clear that when accompanied by severe anomia, the lesions extended either forward to the anterior part of the middle temporal gyrus or medially to the parahippocampal gyrus. It is suggested that the disconnection of association fibres between the parahippocampal, fusiform, middle, and inferior temporal gyri, especially between the parahippocampal gyrus and the other temporal gyri, or the cortical damage to the posterior part of these gyri is essential for the production of anomia.

D008279	Magnetic Resonance Imaging	Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.

D000381	Agraphia	Loss or impairment of the ability to write (letters, syllables, words, or phrases) due to an injury to a specific cerebral area or occasionally due to emotional factors. This condition rarely occurs in isolation, and often accompanies APHASIA.

D000849	Anomia	A language dysfunction characterized by the inability to name people and objects that are correctly perceived. The individual is able to describe the object in question, but cannot provide the name. This condition is associated with lesions of the dominant hemisphere involving the language areas, in particular the TEMPORAL LOBE.
