Abstract
In this paper, we examined the ventricle shapes of centenarian brains in comparison with those of elderly, mild cognitive impairment (MCI) and Alzheimer’s Disease (AD). The MRI datasets obtained from Centenarian Study (CS) and the ADNI project are analyzed via the spherical harmonics (SPHARM) shape analysis pipeline. Our results indicate that if the elderly brains are used as comparison baseline, there is no significant difference between centenarian and elderly brains, while the differences between elderly and MCI/AD brains are significant; if the centenarian brains are used as comparison baseline, the differences between centenarian and MCI brains are moderate, but much more significant differences between AD and centenarian brains appear. Further comparisons of volume and shape analysis suggest that ventricle shape characteristics could potentially be a more sensitive biomarker of AD progression than the traditionally assumed ventricle volumes.
