Study Population: A total of 2530 children, adolescents, and adults will be recruited. Most subjects will not be able to complete all procedures. We seek to comprehensively study 150 juveniles with only a current anxiety disorder, 60 juveniles with current major depression, 150 juveniles with no psychiatric disorder, 100 adults with major depression, 60 adults with an anxiety disorder, and 150 adults with no psychiatric disorder. To achieve this, we are recruiting 2530 individuals.
Design: Subjects will be tested using fMRI paradigms designed to examine brain regions engaged when processing motivationally salient stimuli, as assessed during attention, memory, social interaction, reward, and fear-conditioning paradigms. After these initial fMRI tests, subjects with depression or an anxiety disorder receive treatment. Treatment will comprise open treatment with either fluoxetine or CBT, augmented with computer-based attention retraining, delivered in a randomized-controlled design, with random assignment to either active or placebo attentiontraining regimens. Adolescent subjects then will be re-tested after eight-weeks using only the attention, memory, and conditioning paradigms.
Outcome Measures: Prior imaging studies note that tasks requiring attention modulation, emotional memory, social interchange, and fear conditioning engage brain regions previously implicated in adult mood and anxiety disorders. These regions include most consistently the amygdala and ventral prefrontal cortex. Moreover, imaging studies of reward function implicate the striatum and prefrontal cortex in adult mood disorders. As a result, we hypothesize that attention, memory, social interaction, reward, and conditioning paradigms will engage the amygdala, ventral prefrontal cortex and striatum in both psychiatrically healthy and impaired subjects. Moreover, we hypothesize that these healthy and psychiatrically impaired groups will differ in the degree of engagement.
Juvenile subjects also will be treated for eight-weeks, and a subset will be re-tested with fMRI. We predict that pre-treatment abnormalities in neural circuitry will predict response to treatment, such that increased amygdala and prefrontal activation will occur in individuals who show the strongest response to treatment. Moreover, we hypothesize that effective treatment will normalize abnormalities in attention and emotional memory, as manifest in fMRI.
