Resting-state functional connectivity patterns are altered in adolescents diagnosed with gender dysphoria

Background

While several studies showed altered functional connectivity (FC) patterns in brain resting-state networks in transgender adults, it is unclear whether such patterns also exist in children and adolescents diagnosed with gender... [ view full abstract ]

Aim(s)

We aimed to address both above-described research questions by determining how FC patterns in boys diagnosed with GD, girls diagnosed with GD, cisgender boys (CBs) and cisgender girls (CGs) are related to each other. [ view full abstract ]

Main Outcome Measures

We included 31 pre-pubertal children (18 boys) and 40 adolescents (19 boys) diagnosed with GD and 39 prepubertal (21 boys) and 41 adolescent (20 boys) cisgender controls. Using independent component analysis we identified the... [ view full abstract ]

Methods

FC connectivity within the SMNs, auditory network, visual networks, DAN, left and right WMNs, DMN and SN. [ view full abstract ]

Results

In cisgender children, no group differences in FC in any of the networks were observed. In cisgender adolescents, we found a sex difference in FC within the SMN-II and DMN. In the same networks we found a difference between... [ view full abstract ]

Conclusion

In adolescents diagnosed with GD we found evidence for sex-atypical FC patterns within the SMN-II and DMN. In visual network-II, no sex differences were found but boys diagnosed with GD differed from all other groups. Hence,... [ view full abstract ]
