developed by Northwestern Medicine® scientists, a breakthrough
approach that provides the first objective, scientific diagnosis for
depression. The test identifies depression by measuring the levels of
nine RNA blood markers. RNA molecules are the messengers that
interpret the DNA genetic code and carry out its instructions.
The blood test also predicts who will benefit from cognitive
behavioral therapy based on the behavior of some of the markers. This
will provide the opportunity for more effective, individualized
therapy for people with depression.
In addition, the test showed the biological effects of cognitive
behavioral therapy, the first measurable, blood-based evidence of the
therapy's success. The levels of markers changed in patients who had
the therapy for 18 weeks and were no longer depressed.
"This clearly indicates that you can have a blood-based laboratory
test for depression, providing a scientific diagnosis in the same way
someone is diagnosed with high blood pressure or high cholesterol,"
said Eva Redei, who developed the test and is a professor of
psychiatry and behavioral sciences at Northwestern University Feinberg
School of Medicine. "This test brings mental health diagnosis into the
21st century and offers the first personalized medicine approach to
people suffering from depression."
