| Research Abstract |
Using the anterior medial temporal lobe atrophy on conventional axial MRI as a marker for argyrophilic grain dementia (AGD), we clinically identified patients with AGD. We performed voxel-based morphometry (VSRAD advance using SPM8 and DARTEL) and examined apolipoprotein E (ApoE) phenotypes in 100 patients with AGD and 100 patients AD to clarify the morphological and genetic features of AGD. VSRAD revealed the AGD group had significantly higher Z-scores, reflecting the medial temporal lobe atrophy, than the AD group. The rate of ApoE4 carrier was significantly lower in AGD group than in AD group (31% vs 59%), suggesting that ApoE4 has less impact on AGD compared to AD.
