Brain Age Gap Associations with Externalising Behaviours in Youth: A Longitudinal Investigation in the Adolescent Brain Cognitive Development (ABCD) Cohort

Angela Asikin, Rachel Visontay, Emma Krogh Devine, Lindsay M. Squeglia, Hollie R. Byrne, Louise R. Mewton

This study investigates the association between brain age gap and externalising behaviours in youth, finding a cross-sectional link that weakens over time.

The Brain Age Gap as a Predictor of Alcohol Initiation in Adolescence

Hollie R. Byrne, Rachel Visontay, Emma Krogh Devine, N. E. Wade, Joanna Jacobus, A.J. Moore, Lindsay M. Squeglia, Louise R. Mewton

The paper examines if deviations in brain aging (BrainAGE) predict alcohol initiation and use behavior in adolescents, finding a link with initiation but not with drinking patterns.

Longitudinal Neurocognitive Trajectories in a Large Cohort of Youth Who Use Cannabis: Combining Self-Report and Toxicology

Natasha E. Wade, Ryan M. Sullivan, Alexander L. Wallace, Rachel Visontay, Veronica Szpak, Krista M. Lisdahl, Marilyn Ann Huestis, Priscila Dib Gonçalves, Hollie R. Byrne, Louise R. Mewton, Joanna Jacobus, Susan Frances Tapert

The paper examines how cannabis use onset and THC/CBD exposure affect neurocognitive trajectories in adolescents using longitudinal data from the ABCD Study.

Unified Multi-Cohort Harmonisation and Normative Modelling of Neuroimaging Data via Hierarchical GAMLSS

Mai Phuong Ho, Nikita K. Husein, Lei Fan, Rachel Visontay, Hollie R. Byrne, Emma Krogh Devine, Lindsay M. Squeglia, Perminder Singh Sachdev, Jiyang Jiang, Wei Xiong Wen, Louise R. Mewton

This paper introduces a hierarchical GAMLSS framework for harmonizing and modeling neuroimaging data across multiple cohorts, showing improved removal of cohort effects and preservation of biological signals.

Age- and alcohol-related differences in adolescent neurometabolite levels

Maria I. Perica, Anna E. Kirkland, Louise R. Mewton, Lindsay M. Squeglia

This study examines age- and alcohol-related differences in neurometabolite levels in the dorsal anterior cingulate cortex of adolescents using magnetic resonance spectroscopy.

Structural Covariance Network Properties Predictive of Early Adolescent Alcohol Initiation

Hollie R. Byrne, Rachel Visontay, Emma Krogh Devine, Natasha E. Wade, Joanna Jacobus, Lindsay M. Squeglia, Louise R. Mewton

This study finds that structural covariance network properties in children aged 9-10 years predict early alcohol initiation before age 15.
