| Abstract: | We report the case of a 61-year-old woman with a left thalamic hemorrhage causing agraphia of Kanji (morphograms). Single-photon
emission computed tomography (SPECT) showed a decrease in the blood flow in the left thalamus from the superior temporal convolution
to the parietal lobe, as well as in the frontal lobe while computed tomography showed no remarkable lesions in the cortex.
The agraphia in this case may be due to the thalamic lesion itself, but the SPECT findings strongly suggest that a secondary
cortical lesion may be involved in producing the higher cognitive disorder. |
