A Breakthrough in Diagnosing Depression: The First Blood Test to Predict the Illness

A Breakthrough in Diagnosing Depression: The First Blood Test to Predict the Illness

Posted: April 20, 2012

Story highlights


Results of research by a team of researchers at Northwestern Feinberg School of Medicine in Chicago were published in Translational Psychiatry on April 17th, showing that a blood test can diagnose depression in teens. This marks the development of a biologically-based diagnostic tool for mental illness, similar to diagnostic tools available for most physical illnesses. Currently, a depression diagnosis in teens relies on a patient’s willingness and capacity to accurately report symptoms and their physician’s subjective observations. A more objective diagnostic tool may lead to earlier diagnoses, thus potentially preventing other risk factors of teen depression including substance abuse, a range of physical illnesses and suicide.

NARSAD Grantee, Adelaide Robb of the Children’s National Medical Center in Washington, D.C. comments with cautious optimism in the article: “Taking something from an animal model and saying it means something in people is making a big leap. A finding among 14 is not the same as saying something is present in 1,000 people.” She continues by acknowledging that this is a solid first step that gives researchers an idea of where to look for further blood-test development. “If we could identify several subtypes of depression, we could, hopefully, target treatments for subsections of people with certain abnormal neurochemicals,” she says.
