A Study Of The Relation Between Chinese Agraphia And The Location Of Brain Damage

Objects: To study the relation between Chinese agraphia and the locations of brain damage, the plasticity of the adjacent structure of the damage, the mechanism of Chinese agraphia and its theoretical basis of the rehabilitation model. Methods: ABC and CAB were used to examine the abilities of oral and written language and other cognitive dysfunction. The morbidity difference between the left and the right was compared. Then computerized image-processing technology was used to standardize and reconstruct the 2D/3D skull CT/MM images. The results substracted by the controls were showed directly. Results: In 63 cases, 48 cases were injuried on the left heminsphere, of which 30 were aphasic and 32 were agraphic. 15 cases were injuried on the right heminsphere, of which 3 were aphasic and agraphic. The morbidity difference between the left and right was signicant. The image-processing results showed that AAg nidi focused on the left deep albae of FL and PL, PAg nidi focused on the posterior parts of the left 1st and 2nd of FL, MAg nidi were dispersed near the left basal ganglion and thalamus. VAg nidi focused on the left OL. Coii cl its ion: Chinese agraphia is relevant to extensive area of the brain and writing behavior relys on the cooperation of the whole neuromechanism. Different types of agraphia have their own characters. Chinese agraphia has a special relation with the location of brain damage. .Some parts may be responsible for some writing ability.
