fMRI Detects Brain Imbalance Linked to Future Teen Depression

A new study suggests an imbalance of functioning in attention-related brain systems may help forecast the course of teen depression.

Researchers discovered faulty connections between frontal and insular brain networks were associated with development of severe depression among teens. Moreover, researchers discovered the abnormal connection patterns predicted increased depressive symptoms two weeks later.

Proper coordination of frontoinsular brain networks help us regulate our attention between external goals and self-focused or emotional thinking.

“The teen years are a time of remarkable growth and opportunity, as young people forge new relationships, learn how to navigate intense emotions, and make the transition to independence. However, it is also during adolescence that a high and growing number of teens experience clinical depression and related mood problems for the first time,” said first author Roselinde Kaiser, PhD, University of Colorado Boulder.

The study appears in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging.

“Our challenge as clinicians, scientists, and parents, is: how do we predict which teens will experience mood problems in the near future?”

Dr. Kaiser and colleagues tested the idea of using fMRI to predict future mood health. They measured the activity of frontoinsular networks while adolescents played a difficult computer game involving emotional images. Current prediction tools mostly use self-reporting, which can be unreliable in teens.

“Our results showed that adolescents who showed imbalanced coordination across brain systems — that is, lower coordination among areas involved in goal-directed attention, and higher coordination among areas involved in self-focused thought — went on to report bigger increases in depression two weeks later, bigger mood swings, and higher intensity of negative mood in daily life,” said Dr. Kaiser.

Network functioning provided a better prediction of future mood health beyond current symptoms — a critical distinction, the authors write, as it suggests that frontoinsular network functioning could predict who might develop more severe depression between two teens with the same current symptoms.

“This very interesting study highlights the important role that frontoinsular circuits, measured using fMRI during the processing of emotional stimuli, may play in regulating our mood, and how impairment in the function of this network may underlie present and ongoing negative mood states,” said Cameron Carter, MD, Editor of Biological Psychiatry: Cognitive Neuroscience and Neuroimaging.

Although the study assessed mood health at only two weeks later, the findings indicate that frontoinsular network functioning may be useful to predict future mood health in teens.

Investigators explain that if their findings are confirmed in longer clinical studies, fMRI scans could provide a neurobiological risk predictor to help guide interventions to prevent severe depression.
