What are the Developmental Trajectories for Gray and White Matter?
NIMH scanned children every 2 years for 8-10 years (N=1000 scans; ages 4-22) Analysis in collaboration with UCLA (P. Thompson), MNI (A. Evans)

Thompson/Sowell 2003 (N=45) Von Economo 1929

Cortical Thinning During Brain Development:
Primary Cortices -> Association Cortices 13 children scanned with MRI every 2 years for 8 years What is the dynamic trajectory of cortical thinning? Gogtay/ Thompson PNAS 2004

Time-Lapse Map of Brain Development (PNAS, 2004)

Childhood Onset Schizophrenia
(COS; N=94) Onset before age 13; Unmodified DSM IIIR/IV criteria Premorbid IQ >70; No Primary Neurological Disorder Severe, treatment refractory Rare (~ 1 in 30,000 – 50,000) Continuous with adult onset schizophrenia but somewhat less confounded (e.g., substance abuse)
7
Derailment of Teenage Brain Development 1
Derailment of Teenage Brain Development 1. Teens with Schizophrenia show a progressively spreading wave of gray matter loss (Thompson PNAS 2001) 2. Worse SANS, SAPS, and CGAS scores at follow-up correlate with greater loss at follow-up 3. Follows trajectory of normal brain maturation but exaggerated (up to 5% loss/year; worst in frontal cortex)
