New Riemannian framework analyzes brain aging and Alzheimer's impact on corpus callosum

Researchers have developed a novel Riemannian shape-space framework to analyze age-related morphological changes in the corpus callosum, a key white-matter structure in the brain. Applied to the OASIS-1 cohort, this method represents CC contours in Kendall shape space, removing translation, rotation, and scale variations. The analysis revealed that the Genu and Anterior Body regions account for a significant portion of age-related shape change in cognitively normal individuals. In contrast, Alzheimer's disease appears to disrupt this typical aging trajectory, explaining less than 0.5% of shape variance. AI

IMPACT This research introduces a novel shape analysis technique that could improve the understanding and diagnosis of neurodegenerative diseases.

    Riemannian Shape Analysis of the Corpus Callosum in Kendall Space: Aging and Alzheimer's Disease

    arXiv:2610.05326v2 Announce Type: replace Abstract: The corpus callosum (CC) is a major white-matter structure and a well-established marker of brain aging, but most studies quantify it using scalar summaries that discard its boundary geometry. We present a Riemannian shape-space…
