In Hangeul, the graphemes of syllables are organized in horizontal, vertical and mixed (both horizontal & vertical) orientations, and the graphemic position of consonant(s) and vowel(s) within a each syllable needs to be maintained within a square pattern. We investigated the characteristics of writing errors of 9 stroke patients with right hemisphere (RH) lesions and compared it to the performances of 15 normal subjects. The subjects were asked to write to dictation of 90 Korean syllables. One of the interesting findings was that our patients manifested visuospatial errors which are not commonly observed in other language-speaking (e.g., English) patients due to the unique syllabic organizations of Korean writing system. The prominent errors in the RH group could be explained by the impaired RH which normally controls the visuospatial functions.

A callosal disconnection syndrome results in the functional independence of each hemisphere caused by ACA infarction, head injury or callosal operation for epilepsy. Clinical features are characterized by left unilateral tactile anomia, left unilateral agraphia, left unilateral apraxia, difficulty in copying drawings, dyscalculia and alien hand syndrome. Taeumchowe-tang(太陰調胃湯) is used to treat Taeumin(太陰人) Wewansuhanpyohanbyung(胃脘受寒表寒病). A 47 year-old man, following callosal infarction, was detected on MRI with left agraphia, dyscalculia and alien hand syndrome, but no left ideomotor apraxia or left apraxia. He was treated with Taeumchowe-tang. Significant improvement of clinical symptoms was seen, so it is here reported.
