A new blood test diagnoses major depression in teens—an approach that offers an objective diagnosis by measuring a specific set of genetic markers.
The current method of diagnosing depression is subjective. It relies on the patient’s ability to recount his or her symptoms and the physician’s ability and training to interpret them.
Diagnosing teens is an urgent concern because they are highly vulnerable to depression and difficult to accurately diagnose due to normal mood changes during this age period.
The test also is the first to identify subtypes of depression. It distinguished between teens with major depression and those with major depression combined with anxiety disorder. This is the first evidence that it’s possible to diagnose subtypes of depression from blood, raising the hope for tailoring care to the different types.
“Right now depression is treated with a blunt instrument,” says Eva Redei, a professor of psychiatry and behavioral sciences at Northwestern University Feinberg School of Medicine and lead investigator of the study, published in Translational Psychiatry.
“It’s like treating type 1 diabetes and type 2 diabetes exactly the same way. We need to do better for these kids.
“This is the first significant step for us to understand which treatment will be most effective for an individual patient,” adds Redei. “Without an objective diagnosis, it’s very difficult to make that assessment. The early diagnosis and specific classification of early major depression could lead to a larger repertoire of more effective treatments and enhanced individualized care.” [continue reading…]

Depressed teens who report low levels of impairment related to drug or alcohol use tended to respond better to depression treatment than depressed teens with higher levels substance-related impairment, according to an analysis of data from the NIMH-funded Treatment of SSRI-Resistant Depression in Adolescents (TORDIA) study. However, it is unclear whether less substance-related impairment allowed for better response to depression treatment, or if better treatment response led to less substance-related impairment. The study was published in the December 2009 issue of the Journal of the American Academy of Child and Adolescent Psychiatry. [continue reading…]

In a prospective study of over 1800 interviewed young Finnish twins, early-onset depressive disorders at age 14 significantly predicted daily smoking, smokeless tobacco use, frequent illicit drug use, frequent alcohol use and recurrent intoxication three years later, even among those adolescents who were not users at baseline.
