New year🎊, new preprint📰 Using multimodal brain-age prediction models trained and tested on 4-wave MRI data from #ABCD, we examined how deviations in brain age align with changes in internalising and externalising symptoms across 10 waves. 1/4🧵
Synchrony between brain age maturation and internalising and externalising symptoms across adolescence
Abstract Background: Adolescence is a period of rapid neurobiological and behavioural change, yet it remains unclear how deviations from normative brain maturation relate to the development of interna...
