Could depression actually be a form of infectious disease?
Could depression actually be a form of infectious disease?
Major depressive disorder (MDD) should be re-conceptualized as an infectious disease, according to Turhan Canli, PhD, Associate Professor of Psychology and Radiology at Stony Brook University.

According to topix.com, Dr.Canli suggests that major depression may result from parasitic, bacterial, or viral infection. He presents examples that illustrate possible pathways by which these microorganisms could contribute to the etiology of MDD.

MDD remains highly prevalent disease with some 15 to 20 percent of the population experiencing MDD at some point. Recurrence is common, and pharmacological treatments have not changed. Because the causal aspects of the disease are not clearly defined, research to find causes remains paramount to help improve treatments.

"Given this track record of MDD, I propose reconceptualizing the condition as some form of infectious disease," said Dr. Canli,. "Future research should conduct a concerted effort search of parasites, bacteria, or viruses that may play a causal role in the etiology of MDD."

First, he points out that patients with MDD exhibit illness behavior such as loss of energy, and that inflammatory biomarkers in MDD also suggest an illness-related origin. Second, he describes evidence that parasites, bacteria and viruses that infect humans in a way that alters their emotional behavior. Thirdly, Dr. Canli brings the notion of the human body as an ecosystem for microorganisms and the role of genetics.

Based on these points, Dr. Canli suggests a major research step would be to conduct large-scale studies with depressed patients, controls, and infectious-disease related protocols to determine the association or causal nature of infectious disease and depression.
