Impaired spatial dynamic functional network connectivity and neurophysiological correlates in functional stroke mimics

Abstract

The present study investigated spatial dynamic functional network connectivity (dFNC) in patients with functional hemiparesis (i.e., functional stroke mimics, FSM). The aim of this work was to assess dynamic brain states, which represent distinct dFNC patterns that reoccur in time and across subjects. Resting-state fMRI data were collected from 15 patients with FSM (mean age=42.3±9.4, female=80%) and 52 age-matched healthy controls (HC, mean age=42.1±8.6, female=73%).
