Neuropsychopharmacology. 2026 Jul 10. doi: 10.1038/s41386-026-02491-2. Online ahead of print. ABSTRACT The structural neuroanatomy underlying Major Depressive Disorder (MDD) remains elusive and even large-scale neuroimaging studies and meta-analyses produced inconsistent outcomes with marginal effect sizes. Furthermore, the replicability of brain-psychopathology associations is under scrutiny, attributable to inadequately powered sample sizes and inflated effect sizes. The present study aimed to examine the effect sizes, replicability, and generalizability of brain structural alterations in MDD, harnessing the wealth of three large-scale clinical cohorts. We used three independent cohorts totaling n = 4021 deeply characterized participants (aged 15-65 years), encompassing MDD patients […]

Hum Brain Mapp. 2026 Jul;47(10):e70595. doi: 10.1002/hbm.70595. ABSTRACT Specific phobia (SPH) is a prevalent anxiety disorder and may involve advanced biological aging. However, limited brain age research has been conducted in anxiety disorders. This mega-analysis investigated brain aging in SPH participants within the ENIGMA-Anxiety Working Group. 3D brain structural MRI scans from 17 international samples (600 SPH individuals, of whom 504 formally diagnosed and 96 questionnaire-based cases; 1134 controls; age range: 22-75 years) were processed with FreeSurfer. Brain age was estimated from 77 subcortical and cortical regions with a publicly available ENIGMA brain age model. The brain-predicted age […]
