Neuro-affective Response to Light in Depressed Adolescents and Young Adults

Sponsor: University of Pittsburgh

Summary

The goal of this neuroimaging pilot study is to understand developmental differences in the impact of therapeutic wavelength light (blue light) versus a non-therapeutic wavelength (red light) on emotional brain function in depression. The main questions this study aims to answer are: * Does acute exposure to blue light (vs red light) stabilize emotional brain function in depressed individuals? * Are stabilizing effects of blue light (vs red light) stronger for blue light in adolescents than young adults? Participants will complete: * A magnetic resonance imaging brain scan, in which we will examine the effect of blue versus red light on emotional brain function at rest and in response to rewards and losses. * A pupillometry test of sensitivity to blue vs red light * Clinical interviews and surveys * Screening measures for drug and alcohol use, MRI safety, and current pregnancy \[if relevant\] * Home sleep tracking with sleep diary and actigraphy for one week
