Reduced medial temporal volume in PS youth relative to TD youth develops in early adolescence. Voxelwise examination of nonlinear group-by-age interactions reveals significant differences in the developmental pattern of bilateral medial temporal lobes. Whereas ICV-adjusted medial temporal volumes are stable in TD youth, PS youth lose medial temporal volumes in late childhood and early adolescence, resulting in lower MTL volumes bilaterally by mid-adolescence.
