The neuropathology of depression is related to abnormal inter-regional structural covariance indicating a brain maturational disruption. However, most studies focus on group-level structural covariance aberrance and ignore the interindividual heterogeneity. For that reason, we aimed to identify individualized structural covariance aberrance with the help of individualized differential structural covariance network (IDSCN) analysis.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291722002380_sec_a2\" sec-type=\"methods\"><jats:title>Methods<\/jats:title><jats:p>T1-weighted anatomical images of 195 first-episode untreated patients with depression and matched healthy controls (<jats:italic>n<\/jats:italic> = 78) were acquired.

Despite this heterogeneity, altered edges within subcortical-cerebellum network were often shared by most of the patients. Two robust neuroanatomical subtypes were identified. Specifically, patients in subtype 1 often shared decreased motor network-related edges. Patients in subtype 2 often shared decreased subcortical-cerebellum network-related edges. Functional annotation further revealed that differential edges in subtype 2 were mainly implicated in reward\/motivation-related functional terms.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291722002380_sec_a4\" sec-type=\"conclusions\"><jats:title>Conclusions<\/jats:title><jats:p>In conclusion, we investigated individualized differential structural covariance and identified that decreased edges within subcortical-cerebellum network are often shared by patients with depression.
