Research Abstract |
Amnestic mild cognitive impairment(aMCI) is considered to be a transitional stage in Alzheimer's disease(AD). Several studies using diffusion tensor imaging(DTI) showed abnormalities of the white matter in aMCI patients. Subjective cognitive impairment(SCI) is thought to be a preclinical stage in the course of AD that may precede aMCI. In this DTI study, we investigated on SCI subjects(n=22) by comparing age matched early AD(n=27), aMCI(n=28) and normal control(NC)(n=28). SCI subjects had lower FA region in the posterior cingulum than NC. This finding may represent early subtle change in the course of dementia.
