발달성 말더듬: 전도실어증과의 연계성에 대한 고찰

초록

Little research has been conducted on the probable correlates betweenlanguage and speech disorders. This study is mainly aimed to provide a plausibleneurological explanation on the probable correlates between developmental stutteringand conduction aphasia based on the recent findings from neuro-imagingresearch associated with the neural bases of the respective speech and languagedisorder. The explanation can be summarized as the following: Both disorders,although seemingly different, can be considered as disorders in sensori-motor integrationwhose neuro-anatomical area is arcuate fasciculus(AF) or sylvian fissure atthe parietal-temporal boundary(Spt). Different symptoms associated with each ofthe disorders can be explained by the notion that while developmental stutteringviewed as a disorder due to the “reduced” function in sensori-motor integration,conduction aphasia can be considered as a disorder due to the “disrupted” functionin sensori-motor integration.
