Is Inflammation What's Causing Your Depression? Another culprit: psychological stress, which can cause an increase in these unhealthy habits but also independently increases inflammation. It's a vicious circle: Stress triggers inflammation, which can cause ills ranging from heart disease to pain and depression. Those diseases are stressors themselves, which in turn can lead to more inflammation. Emotional or physical trauma early in life might be a particularly potent cause.

- There is a well studied, although only partially understood phenomenon called inbreeding depression. Inbreeding depression is thought to be caused primarily by the collection of a multitude of deleterious mutations, few in themselves fatal, but all diminishing fitness. Normally, in an outbreeding population these alleles would be selected against, hidden, or corrected by the presence of good alleles (versions of genes) in the population.

What causes depression? Another goal of gene research, of course, is to understand how, exactly, biology makes certain people vulnerable to depression. For example, several genes influence the stress response, leaving us more or less likely to become depressed in response to trouble. A 2003 discovery supports this idea.esearch shows that the hippocampus is smaller in some depressed people. For example, in one fMRI study published in The Journal of Neuroscience, investigators studied 24 women who had a history of depression.
