About the Presentations

Childhood Onset Schizophrenia: Rare But Worth Studying
Judith L. Rapoport, MD
Across all of medicine and pediatrics, the study of very early-onset forms of illness has contributed much to our knowledge of the underlying biology and genetics of the disease. For 20 years the NIMH has been observing children and adolescents with onset of schizophrenia before age 13, a rare and severe form of psychosis. Several striking results have emerged. Children with schizophrenia have a high rate of very early problems with speech, language and motor development, and almost one-third had symptoms of autism spectrum disorder. Brain abnormalities were more striking than in adult-onset patients, and were progressive. Genetic studies showed a high rate of rare deletions or duplications in risk genes for the disorder. Finally, many treatment refractory children responded to clozapine as has been seen in adults. Ongoing studies of the biology of the illness will be discussed.

When Noise Is Not Noise: The Role of Spontaneous Fluctuations in Brain Function Throughout Life
Xavier Castellanos, MD
Throughout her storied career, Judith Rapoport has overturned the scientific dogma of the day on multiple occasions. At the NIMH she has always encouraged high-risk/high-reward scientific inquiry. Dr. Castellanos worked with Dr. Rapoport for a decade, during which they initiated a landmark longitudinal study of brain structure in people with ADHD that continues to be remarkably productive under her leadership. Inspired by Dr. Rapoport’s encouragement to “always go for the jugular,” Dr. Castellanos hypothesized that ultra-low frequency spontaneous fluctuations in the brain reveal fundamental physiological principles underpinning brain self-organization, and that examining such low frequencies offers a path to understanding the physiology of ADHD. This link between behavioral and cognitive inconsistency and brain architecture is now being actively investigated.

Accelerating the Pace of Psychiatric Research: The Promise of New Models and Methods
Michael Milham, MD, PhD
Over years of working together, Xavier Castellanos has repeatedly challenged Dr. Milham to think outside the box and stressed the need to change science at the cultural level, not just at the bench. Psychiatry remains the only field of medicine without objective biological measures of the presence of illness or treatment response. Dr. Milham will discuss recent advances in imaging methodologies and their potential to lead to the development of clinical tools to aid in diagnosis, treatment selection and assessment. He will also discuss recent efforts to promote open neuroscience as a means of accelerating the pace of scientific discovery, in particular the 1000 Functional Connectome Project and the International Neuroimaging Data-Sharing Initiative. Co-founded by Dr. Milham, these endeavors have distributed thousands of brain images to researchers globally, yielding novel insights into brain architecture and the impact of psychiatric disorders such as ADHD.

The Contribution of Temperamental Biases to Adult Development
Jerome Kagan, PhD
Dr. Kagan will present conclusions on a study of a group of infants followed from 4 months to age 18 years:

  • The high reactive infants are biased to become shy, timid toddlers. As they grow, their timidity is muted somewhat, but they develop unrealistic anxieties. They are at higher than average risk for social anxiety and depression during adolescence. Brain imaging reveals a thicker cortex in a small area in the ventromedial prefrontal region of the right hemisphere. They also show shallow habituation of the BOLD signal during repetitions of unfamiliar scenes.
  • The low reactives become sociable, fearless toddlers and as adolescents are free of unrealistic worries. Importantly, the few low reactives who reported social anxiety or depression (mainly females) did not possess a thicker cortex in the ventromedial area and did not show a large BOLD signal to the amygdala during the unexpected scenes. Clinicians could use these biological markers to differentiate adolescents with the same DSM diagnosis.

Is the Glass Half Empty or Half Full? Behaviorally Inhibited Children Learn About the Social World
Nathan A. Fox, PhD
Jerome Kagan first described the temperament of behavioral inhibition in 1984 and he linked behavioral and physiological profiles to circuitry in the brain that underlie responses to novelty and fear. Infants with the temperament of behavioral inhibition display heightened motor reactivity and emotional distress when confronted with novel or unfamiliar events. As they get older, some display social reticence, withdrawal and developing anxiety, while others present as quiet, thoughtful and reflective. Dr. Fox will discuss mechanisms that contribute to the developmental trajectories of behaviorally inhibited children, including research on the importance of brain systems underlying motivations to approach or withdraw. He will also tie these findings to the significant contributions that Dr. Kagan has made to our understanding of the biology of individual differences.

Temperament’s Fingerprint: Attention as a Mechanism for Socioemotional Development
Koraly Perez-Edgar, PhD
As first described by Dr. Jerome Kagan, behavioral inhibition is a biologically-based temperamental trait marked by sensitivity to novelty and discomfort in social situations. It is also one of the strongest markers of risk for anxiety. Yet, for most children, maturational and environmental forces work in tandem to ameliorate this risk. A growing literature suggests that attentional biases to evocative stimuli may play a causal role in emerging anxiety. Specifically, attention biases to threat are evident in both children and adults with anxiety and children temperamentally at risk for developing anxiety. There is a systematic relation between these biases and risk at the behavioral, genetic and neural level. This attention bias also moderates the emergence of social withdrawal. Building on the work of Drs. Kagan and Fox, Dr. Pérez-Edgar will examine this pattern within a larger biobehavioral context reflected in the neural and genetic correlates of inhibition and anxiety.
