White matter disturbances in major depressive disorder: a coordinated analysis across 20 international cohorts in the ENIGMA MDD working group

Laura S van Velzen, +81 more
- 01 Jul 2020 - 
TL;DR: In this paper, the authors examined WM anisotropy and diffusivity in 1305 MDD patients and 1602 healthy controls (age range 12-88 years) from 20 samples worldwide, which included both adults and adolescents, within the MDD Working Group of the Enhancing Neuroimaging Genetics through Meta-Analysis (ENIGMA) consortium.
Journal ArticleDOI

Increased power by harmonizing structural MRI site differences with the ComBat batch adjustment method in ENIGMA.

Joaquim Radua, +133 more
- 01 Sep 2020 - 
TL;DR: Whether the batch adjustment method, ComBat, can further reduce site-related heterogeneity and thus increase statistical power and recommend applying the ComBat function to attenuate potential effects of site in ENIGMA projects and other multi-site structural imaging work.
Journal ArticleDOI

Cortical thickness across the lifespan: Data from 17,075 healthy individuals aged 3-90 years

Sophia Frangou, +211 more
- 17 Feb 2021 - 
TL;DR: In this paper, the authors used fractional polynomial regression to quantify the association between age and cortical thickness, and computed normalized growth centiles using the parametric Lambda, Mu, and Sigma method.
Journal ArticleDOI

Greater male than female variability in regional brain structure across the lifespan

Lara M. Wierenga, +194 more
- 12 Oct 2020 - 
TL;DR: The ENIGMA (Enhancing Neuro Imaging Genetics through Meta‐Analysis) Consortium presents the largest‐ever mega‐analysis of sex differences in variability of brain structure, based on international data spanning nine decades of life, finding significant patterns of greater male than female between‐subject variance.
Journal ArticleDOI

Association of Structural Magnetic Resonance Imaging Measures With Psychosis Onset in Individuals at Clinical High Risk for Developing Psychosis: An ENIGMA Working Group Mega-analysis.

Maria Jalbrzikowski, +136 more
- 01 Jul 2021 - 
TL;DR: In a case-control study, baseline T1-weighted magnetic resonance imaging (MRI) data were pooled from 31 international sites participating in the ENIGMA Clinical High Risk for Psychosis Working Group as discussed by the authors.
