Idiopathic generalized epilepsy(IGE)is a group of generalized epilepsy syndromes closely related to genetic factors,with the main clinical manifestation of generalized seizures,which are manifested as generalized or bilateral symmetrical abnormal discharges on electroencephalogram(EEG),and routine MRI is negative.With the use of new methods of MRI,some progress has been made in the study of the mechanism of IGE occurrence and development,but it is still not fully elucidated.In recent years,dynamic functional connectivity(DFC),as a new network analysis method,has been gradually applied to the neuroscientific study of IGE to analyze the association between cognitive dysfunction and dynamic information transfer and integration,which provides valuable new insights into the developmental mechanism of IGE.Insights.In this paper,we summarize the application and progress of DFC research on IGE in recent years,hoping to provide certain reference for IGE research.
