The findings of the present study suggest that the connections within the DMN regions, primarily involving parahippocampal and prefrontal hub regions, are dysregulated in AUD individuals leading to possible neurocognitive deficits and increased impulsivity as observed in the current study and the previous studies. Specifically, the identification of specific connectivity patterns in discrete frequency bands in different stages of AUD may aid in diagnostic and intervention strategies based on brain circuits. These may include connectivity-guided clinical applications such as transcranial magnetic stimulation (e.g., [170]), deep brain stimulation (e.g., [171]), neurofeedback (e.g., [172]), and cognitive training [173], which have been implemented in neuropsychiatric conditions including alcohol/drug addiction and are becoming important tools for treating AUD.
