Caudate-Centric Triphasic Network Reconfiguration Characterizes the Early Progression of Cognitive Impairment in Parkinson’s Disease: A Simultaneous PET/fMRI Study

Key Points

To investigate how the caudate nucleus influences cognitive impairment progression in early Parkinson's disease (PD).
Simultaneous PET and fMRI imaging techniques used to assess brain activity and connectivity.
Focused on the caudate nucleus and its role in network reconfiguration during early cognitive impairment in PD.
Analyzed the shift from hyperconnectivity to network rigidity during disease progression.
Identified a shift from compensatory hyperconnectivity to rigidity in the brain's functional network.
Demonstrated that dopaminergic metabolic deficits are linked to changes in network connectivity.
Provided evidence supporting targeted neuromodulation strategies for early cognitive impairment in PD.

Abstract

The caudate nucleus is central to the interplay between dopaminergic metabolic deficits and functional network reconfiguration during early PD-CI progression, shifting from compensatory hyperconnectivity to network rigidity. These findings provide a mechanistic framework for targeted neuromodulation strategies in early PD-CI.
