Structural brain alterations in bipolar disorder (BD) have been widely reported, yet the hierarchical organization of cortical morphometric networks and their molecular and cognitive underpinnings remain unclear.

We applied the morphometric inverse divergence (MIND) network approach to structural MRI data from 49 BD patients and 119 healthy controls. Principal MIND gradients were derived using diffusion map embedding, followed by multiscale analyses linking gradient alterations to neurotransmitter systems, cognitive-behavioral domains, and transcriptomic profiles from the Allen Human Brain Atlas. Validation was performed in three independent, cross-scanner, cross-race, and cross-age validation datasets.

Bipolar disorder patients showed significant principal gradient alterations in the left rostral middle frontal and lateral occipital cortices, with network-level decreases in the ventral attention and motor networks and increases in frontoparietal and visual networks. Gradient alterations spatially correlated with acetylcholine (VAChT) and GABA (GABAA/BZ) systems, and were associated with cognitive processes involving executive control and visual attention. Transcriptomic analyses identified gene sets enriched for BD-related GWAS loci, expressed predominantly in excitatory and inhibitory neurons, astrocytes, and oligodendrocytes, with preferential enrichment in cortical layers III-IV and developmental windows spanning early fetal to young adulthood.

These findings reveal disrupted hierarchical cortical organization in BD and link macroscale morphometric alterations to specific neurotransmitter systems and transcriptional architectures. The MIND gradient emerges as a potential biomarker bridging structural disruptions with molecular and cognitive mechanisms in BD.

Early life adversity (ELA) is common and cross-sectionally associated with brain gray matter structure, including cortical thickness, cortical surface area, and subcortical volumes in childhood. However, to which degree ELA influences the trajectory of gray matter macrostructural and microstructural development during childhood and adolescence remains largely unexplored.

We included 6414 participants from the Adolescent Brain Cognitive Development study at ages 9–11, where 1923 were followed to ages 11–13. We used linear mixed-effects models to test for associations between MRI-derived longitudinal measures of gray matter macro- (cortical thickness, surface area, subcortical volume) or microstructure (T1w/T2w ratio) and trauma exposure, parental acceptance, household abuse, and being resilient or susceptible to trauma in terms of developing an internalizing disorder.

At ages 9–11, higher levels of parental acceptance, trauma exposure, and being trauma resilient were associated with lower levels of cortical thickness. In contrast, being trauma susceptible was negatively related to hippocampal volume and cortical surface area. Longitudinally, more parental acceptance at baseline was associated with more cortical thinning between ages 9–11 and 11–13, while more household abuse was associated with less change in T1w/T2w ratio over time.

Parental acceptance and trauma resilience are linked to accelerated pace of apparent cortical thinning in youth aged 9–13 years, while household abuse is associated with slower microstructural development, as reflected by smaller longitudinal changes in the T1w/T2w ratio. Threat and deprivation may be distinctly associated with gray matter developmental trajectories in late childhood.

Low self-esteem is an important and potentially modifiable risk factor for the development and outcome of psychotic disorders. The factors involved in low self-esteem in psychotic disorders are not yet fully understood. The current study aims to investigate the cross-sectional and longitudinal associations between (changes in) self-esteem and severity of psychotic symptoms, internalized stigma, negative reaction to antipsychotics, personal recovery, childhood bullying, childhood trauma, and social support in symptomatically remitted first-episode psychosis (FEP) patients.

Data from the ongoing longitudinal Handling Antipsychotic Medication: Long-term Evaluation of Targeted Treatment study were used. Participants were in symptomatic remission for 3–6 months after the FEP. Cross-sectional associations (N = 299) were investigated through Pearson’s correlations, and longitudinal changes (N = 238) were investigated via linear regressions with inverse probability weighting.

Cross-sectionally, we found that lower self-esteem was related to higher severity of symptoms, higher internalized stigma, higher childhood trauma (specifically emotional neglect), higher childhood bullying, more negative side effects of antipsychotic medication, lower personal recovery, and lower social support. Longitudinally, contrary to our hypothesis, we found that higher baseline internalized stigma, higher childhood trauma (specifically emotional abuse), and a higher baseline negative subjective reaction to antipsychotics predicted an increase in self-esteem after 6 months. Furthermore, a decrease in psychotic symptoms, internalized stigma, and negative subjective reaction to antipsychotics, and an increase in social support predicted an increase in self-esteem.

Early intervention programs for psychotic disorders should target factors related to changes in self-esteem. This might improve self-esteem and thereby promote recovery.
