abstract = {Overlapping psychopathological spectra may reflect an
underlying, general liability for mental illness linked to
shared risk factors and common alterations in
neurodevelopmental processes. In three studies, we
investigated how multi-scale features of brain organization
shape topologically heterogeneous levels of transdiagnostic
vulnerability. Combining meta-analytic cortical thickness
maps of 6 major mental disorders with multi-scale data, we
characterized a transdiagnostic cortical coordinate space
framed by connectomic, cytoarchitectonic, and functional
dimensions, along which synchronized brain alterations are
organized. We identified low-dimensional cortical axes of
co-alteration networks, which indicated that the likelihood
of two brain regions to display synchronized illness
effects, regardless of their location on the cortical
landscape, is related to the degree to which these regions
share cytoarchitectonic profiles and are engaged in similar
functional tasks. Moreover, fronto-temporal epicenters
emerged as potential connectome anchors of shared cortical
alterations. We extended these observations towards symptom
domains and explored a continuous coordinate space in which
individuals with mental disorders are embedded based on the
degree to which they express a combination of pathological
brain imaging patterns – partly crossing categorical
diagnoses. Last, we studied adaptation to transdiagnostic
environmental risk factors during adolescence and found that
adolescents’ vulnerability or resilience to environmental
stressors varies during development. This intra-individual
variability was tied to maturational trajectories of
cortical myelination of association cortices, as well as
microstructural and functional network re-organization. In
my contribution, I will present multi-modal insights into
brain organizational principles shaping transdiagnostic
vulnerability.},
