Topological and geometric signatures of brain network dynamics in Alzheimer's disease. [PDF]
Abstract INTRODUCTION This study explores magnetic resonance imaging (MRI) as a promising non‐invasive approach to monitor Alzheimer's disease (AD) and related dementias. We investigate whether dynamic functional connectivity (dFC), which captures time‐varying neural interactions, can reveal sex‐specific brain network disruptions in AD that ...
