Journal ArticleDOI
Subtle in-scanner motion biases automated measurement of brain anatomy from in vivo MRI.
Aaron Alexander-Bloch,Aaron Alexander-Bloch,Liv S. Clasen,Michael Stockman,Lisa Ronan,Francois Lalonde,Jay N. Giedd,Armin Raznahan +7 more
TL;DR: Convergent evidence showed that in‐scanner motion—even at levels which do not manifest in visible motion artifact—can lead to systematic and regionally specific biases in anatomical estimation.
Journal ArticleDOI
Dynamic mapping of cortical development before and after the onset of pediatric bipolar illness.
Nitin Gogtay,Anna E. Ordóñez,David H. Herman,Kiralee M. Hayashi,Deanna Greenstein,Cathy Vaituzis,Marge Lenane,Liv S. Clasen,Wendy Sharp,Jay N. Giedd,David Jung,Tom F. Nugent,Arthur W. Toga,Ellen Leibenluft,Paul M. Thompson,Judith L. Rapoport +15 more
TL;DR: In this article, the authors report the first prospective study of cortical brain development in pediatric bipolar illness for 9 male children, visualized before and after illness onset, and show that the bipolar neurodevelopmental trajectory was generally shared by the children who remained with MDI diagnosis without converting to bipolar I, suggesting that this pattern of cortical development may reflect affective dysregulation in general.
Journal ArticleDOI
Cortical brain development in nonpsychotic siblings of patients with childhood-onset schizophrenia
Nitin Gogtay,Deanna Greenstein,Marge Lenane,Liv S. Clasen,Wendy Sharp,Pete Gochman,Philip Butler,Alan C. Evans,Judith L. Rapoport +8 more
TL;DR: Amelioration of regional GM deficits in healthy siblings was associated with higher global functioning and the process of deficit reduction correlated with overall functioning at the last scan, suggesting a relationship between brain plasticity and functional outcome for these nonpsychotic, nonspectrum siblings.
Journal ArticleDOI
A pediatric twin study of brain morphometry
Gregory L. Wallace,J. Eric Schmitt,Rhoshel K. Lenroot,Essi Viding,Sarah Ordaz,Michael A. Rosenthal,Elizabeth A. Molloy,Liv S. Clasen,Kenneth S. Kendler,Michael C. Neale,Jay N. Giedd +10 more
TL;DR: Understanding the relative contributions of genetic and nongenetic factors on developmental brain trajectories may have implications for better understanding brain-based disorders and typical cognitive development.
Journal ArticleDOI
Childhood onset schizophrenia: cortical brain abnormalities as young adults
Deanna Greenstein,Jason P. Lerch,Philip Shaw,Liv S. Clasen,Jay N. Giedd,Peter Gochman,Judith L. Rapoport,Nitin Gogtay +7 more
TL;DR: Cortical thickness loss in COS appears to localize with age to prefrontal and temporal regions that are seen for both medication naïve and medicated adult onset patients.
