The purpose of this study was to evaluate the functional network connectivity (FNc) changes between the dorsal attention network (DAN) and the other seven intrinsic networks relevant to attention, visual\u2013spatial, executive and motor functions in PD with or without FOG. Forty\u2010three idiopathic PD patients (21 with FOG [FOG+] versus 22 without FOG [FOG\u2212]) and 18 healthy controls (HC) were recruited in this study. The data\u2010driven independent component analysis (ICA) method was used to extract and analyze the above\u2010mentioned resting\u2010state networks (RSNs). Compared with FOG\u2212, FOG+ displayed decreased positive connectivity between the DAN and medial visual network (mVN) and sensory\u2010motor network (SMN) and increased negative connectivity between the DAN and default mode network (DMN). The within\u2010network connectivity in the SMN and visual networks were decreased, whereas the connectivity within DMN was increased significantly in FOG+. Correlation analysis showed that the clock drawing test (CDT) scores were positively correlated with the functional connectivity of mVN (\n                    <jats:italic>r<\/jats:italic>\n                    \u00a0=\u00a00.573,\n                    <jats:italic>p<\/jats:italic>\n                    \u00a0=\u00a00.008) and lateral visual network (lVN) (\n                    <jats:italic>r<\/jats:italic>\n                    \u00a0=\u00a00.510,\n                    <jats:italic>p<\/jats:italic>\n                    \u00a0=\u00a00.022), the Timed Up and Go Test (TUG) duration were negatively correlated with the connectivity of SMN (\n                    <jats:italic>r<\/jats:italic>\n                    \u00a0=\u2009\u22120.629,\n                    <jats:italic>p<\/jats:italic>\n                    \u00a0=\u00a00.003), and the Frontal Assessment Battery (FAB) scores were negatively correlated with the connectivity of DMN in FOG+.
