We have three main findings. First, patients with AUD showed increased FCs in the anterior SN, dorsal DMN, and ventral DMN compared to healthy adults. Patients with AUD also showed decreased FCs in the posterior SN, ventral DMN, and right ECN. Second, patients with AUD showed decreased gray matter volume in neural areas implicated in all the triple networks. Lastly, there was a negative correlation between the gray matter volume and FC in anterior SN, dorsal DMN, and ventral DMN.
