Researchers at Columbia University Medical Center found a physical difference in the brain that may serve as a biomarker for depression.
UPI, reporting on a study published in Neuropsychopharmacology, says researchers came across the discovery while comparing the brains of people at high and low risk for depression based on their family history.
“These findings suggest that looking at activity in the DMN may offer an objective method of identifying people who are at risk of developing major depression,” said Dr. Myrna Weissman, a professor of epidemiology at Columbia University Medical Center.
“This may represent a another way toward advancing prevention and early intervention for this major public health issue.”
Using MRI scans, researchers found the DMN system is more active when people are thinking deeply about something, and shown to have increased connections in people with major depressive disorder.
Dr. Jonathan Posner, an associate professor of clinical psychiatry at Columbia University Medical Center said the research could lead to behavioral interventions, such as meditation and mindfulness – the later has been successful in treating addiction and obsessive compulsive disorder.
