Network-based cortical atrophy predicts longitudinal clinical decline in sporadic behavioral variant frontotemporal dementia.

Key Points

The aim is to investigate how network-based cortical atrophy relates to clinical decline in bvFTD.
Observational analysis of atrophy patterns in bvFTD patients
Assessment of anterior and posterior cortical regions
Longitudinal tracking of clinical outcomes
Atrophy in anterior regions is pronounced at baseline
Posterior default mode network atrophy predicts future clinical decline
Network-based atrophy shows promise as a prognostic tool

Abstract

At baseline, bvFTD is associated with prominent atrophy in anterior cortical regions.Atrophy in the posterior default mode network predicts subsequent clinical decline.Network-based atrophy has potential to be a useful clinical prognostication tool in bvFTD.
