“…Given challenges inherent to neuroimaging research, particularly with clinical developmental samples, big data studies will be essential to continued progress in identifying neurodevelopmental trajectories associated with pediatric anxiety. A growing number of large cross-sectional or longitudinal neuroimaging studies of childhood and/or adolescence are available with measures related to anxiety ( Alexander et al, 2017 ; Casey et al, 2018 ; Evans, 2006 ; Hubbard et al, 2020 ; Jaddoe et al, 2006 ; Jernigan et al, 2016 ; Nooner et al, 2012 ; Pausova et al, 2017 ; Satterthwaite et al, 2016 ; Salum et al, 2015 ; Schumann et al, 2010 ; Somerville et al, 2018 ; Volkow et al, 2018 ). Each of these datasets contains measures of structural and/or functional neuroimaging, anxiety symptoms, and various other relevant measures in cognitive, emotional, social, behavioral, physical, and genetic domains ( Table 1 ).…”
