Could Depression Be Caused By An Infection? by Bret Stetka.
Late last year, Turhan Canli, an associate professor of psychology and radiology at Stony Brook University, published a paper in the journal Biology of Mood and Anxiety Disorders asserting that depression should be thought of as an infectious disease. “Depressed patients act physically sick,” says Canli. “They’re tired, they lose their appetite, they don’t want to get out of bed.” He notes that while Western medicine practitioners tend to focus on the psychological symptoms of depression, in many non-Western cultures, patients who would qualify for a depression diagnosis report primarily physical symptoms, in part because of the stigmatization of mental illness.
“The idea that depression is caused simply by changes in serotonin is not panning out. We need to think about other possible causes and treatments for psychiatric disorders,” says Canli.
His assertion that depression results from infection might seem far-fetched, or at least premature, but there are some data to bolster his claim.
