Brain scanning can preach teen depression weeks before their mood changes, study suggests



Brain scans can PREDICT teen depression weeks before their mood change, study suggests

  • About half of all people who eventually experience depression have their first episode in adolescence
  • Depression in adolescents and adolescents may be hard to diagnose using subjective tests
  • Researchers from Colorado in Colorado discovered that brain awareness systems work differently in teenagers who are or will be depressed
  • They claim that the tests could be a faster and more precise way to capture depression on previous

Clinical depression in teenagers can be diagnosed faster and more precisely by brain searches, suggesting a new study.

Researchers found that an imbalance in functioning in attention-related brain systems can help predict the course of teen depression.

They explained that proper network coordination in the brain helps us regulate our attention between external goals and self-focused or emotional thinking.

But the University of Colorado, Boulder, researchers found abnormalities in network coordination were not only apparent in teens with more severe depression, but predicted increased depressive symptoms two weeks later.

& # 39; Teen years are a time With remarkable growth and opportunity as young people mature new relationships, learn to navigate intense emotions and make the transition to independence, the study says first author Dr. Roselinde Kaiser.

& # 39; However, during adolescence, a high and growing number of teens experience clinical depression and related mood problems for the first time.

& # 39; Our challenge as clinicians, researchers and parents is: how do we predict which teens will experience mood problems in the near future? & # 39;

Dr. Kaiser, an assistant professor in the Department of Psychology and Neuroscience at the University of Colorado Boulder, and her colleagues tested the idea of ​​using MRI to predict future mood health.

They measure the activity of frontoinsular networks, while teens played a difficult computer game with emotional images.

She said that current prediction tools mostly use self-reports, which can be unreliable in teenagers.

& # 39; Our results showed that young people who showed unbalanced coordination across brain systems say dr. Kaiser.

& l39; [1945941] Lower coordination among areas involved in targeted attention and higher coordination between areas involved in self-focused thought – continued to report major increases in depression two weeks later, greater mood swings, and higher intensity of negative mood in daily life. "

She said that the network function provided a better prediction of future mood health in addition to current symptoms – a critical difference, as it suggests that frontoinsular network works, predicting who can develop more severe depression between two teenagers with the same Current Symptoms

The results were published in the journal Biological Psychiatry: Cognitive Neuroscience and Neuroimaging.

"This very interesting study highlights the important role that frontoinsular circulation measured by MRI during the treatment of emotional stimuli can play. to regulate our mood and how weakening in this network's function can support current and ongoing negative mood states, "said Dr. Cameron Carter, editor of the magazine.

Although the study assessed mood health within just two weeks later, he said that the results suggests that frontoinsular networking k works, can be useful to predict future mood health in teens.

If confirmed in longer clinical studies, the research team said their findings suggest that the measure could provide a neurobiological risk prediction to help control interventions to prevent severe depression.
