Major Depression Disorder (MDD), most commonly known as “Depression”, is typically thought of as a genetic or neurological disease. However, Dr. Tuhran Canli, Associate Professor of Psychology and Radiology at Stony Brook University, suggests that MDD be recategorized as a result of a parasitic, bacterial, or viral infection. Canli’s paper, Biology of Mood & Anxiety Disorders, argues how possible pathways from these infections could cause MDD.

The causes of MDD are still unclear, therefore the research is delving more into the causes over the treatments. Dr. Canli suggests that by redefining MDD as an infectious disease, it will push future researchers to focus their attention on parasites, bacteria, or viruses.

Canli’s three major arguments for this change of MDD’s etiology are as follows:

1. MDD patients have a loss of energy, typically found in an illness. Also, the “inflammatory biomarkers in MDD suggest an illness-related origin”.

2. Parasitic, bacterial, and viral infections alter emotional behavior in humans.

3. The body is an ecosystem, made for microorganisms and genetics. These infections alter that ecosystem.

The redefinition of the causes of MDD could have significant help in finding the cause and eventual better treatment of the disease. Has depression been an infection all along?
