Findings of this population-based sibling-matched cohort study corroborate an association of loss of a co-twin at birth with risk of psychiatric disorders, supporting the hypothesis of twin-bond development in utero.

A population-based analysis demonstrates that surviving twins who lose their co-twins by death are at considerably elevated risks of developing psychiatric disorders.

Measures of sleep features such as spindles and slow waves differentiate between young people with 22q11.2 microdeletion syndrome and healthy controls, and may mediate the relationship between this genotype and psychiatric symptoms.

Patients diagnosed with a cardiovascular disease are at higher risk of psychiatric disorders, independent of familial factors shared between full siblings and comorbid conditions.

A dimensional approach to psychiatry demonstrates the specificity and generalizability of a neurocognitive marker of compulsive behavior and intrusive thought via large-scale online testing.

Cumulative exposure to adverse childhood experiences is associated with lower adult resilience among women in a dose-dependent manner, independent of adult socioeconomic factors and social support, indicating that adult female resilience is consolidated in early life.

The multimodal linked independent component analysis promotes a more integrative understanding of transdiagnostic mechanisms of psychopathology.

Structural differences in adolescent brains associated with binge drinking might be preceding the onset of such behavior, suggesting a reevaluation of studies of the effects of alcohol on the adolescent brain.

In paediatric concussions, there are a multiplicity of ways that brain damage gives rise to symptoms, most of which are missed by conventional statistical approaches and study designs.
