How reward sensitivity and the body clock relate to first bipolar episodes in teens

Integrated Reward-Circadian Rhythm Model of First Onset of Bipolar Spectrum Disorders in Adolescence

What this research studies

If you're a teen or the parent of a teen at risk for bipolar disorder, this project follows adolescents over time to see how their responses to rewards and their daily sleep/activity rhythms change before any bipolar symptoms appear. The team measures brain activity linked to reward, behavioral tests and questionnaires of reward responsivity, and objective sleep and circadian measures such as actigraphy and sleep diaries, along with other biological and clinical data. Investigators will test whether chronically high or increasing reward sensitivity and ongoing social/circadian rhythm disruption, alone or together, signal higher risk for first onset of bipolar spectrum disorders. The aim is to find early warning patterns that could eventually guide prevention or early intervention for at-risk youth.

Who could benefit from this research

Good fit: Ideal candidates are adolescents roughly 12–20 years old who have mood symptoms or a family history suggesting higher risk for bipolar spectrum disorders.

Not a fit: People without adolescent-age mood symptoms or family risk, or adults outside the 12–20 age range, are unlikely to be eligible or to benefit directly from this project.

Why it matters

Potential benefit: If successful, this work could reveal early warning signs that enable earlier prevention or targeted support for adolescents at risk for bipolar disorder.

How similar studies have performed: Prior research has linked reward sensitivity and circadian disruption separately to bipolar disorder, but testing an integrated reward–circadian model longitudinally in adolescents at high risk for first onset is a novel approach.
