AbstractGiven that extensive cerebral regions are co-atrophic in semantic dementia (SD), it is not yet known which critical regions (SD-semantic-critical regions) are really responsible for the semantic deficits of SD. To identify the SD-semantic-critical regions, we explored the relationship between the degree of cerebral atrophy in the whole brain and the severity of semantic deficits in 19 individuals with SD. We found that the gray matter volumes (GMVs) of two regions [left fusiform gyrus (IFFG) and left parahippocampal gyrus (IPHG)] significantly correlated with the semantic scores of patients with SD. Importantly, the effects of the IFFG remained significant after controlling for the GMVs of the IPHG. Moreover, the effects of the region could not be accounted for by the total GMV, general cognitive ability, laterality of brain atrophy, or control task performance. We further observed that each atrophic portion of the IFFG along the anterior posterior axis might dedicate to the loss of semantic functions in SD. These results reveal that the IFFG could be a critical region contributing to the semantic deficits of SD.
