Case of Pure Agraphia in Kana and Romaji Without Sensorimotor Deficits After a Small Infarct of the Posterior Limb of the Internal Capsule
Selective impairment of thalamic radiation projecting to the left frontal cortex due to the plIC infarction can result in pure agraphia. Our findings suggest a specific role of the left anterior plIC in writing Kana and Romaji, specifically in sound-to-letter conversion and postorthographic processes. This case underscores the importance of evaluating writing ability in patients with plIC infarctions to avoid overlooking agraphia.
