The two best-known theories are, first, that depression is caused by a [[chemical imbalance]] in the brain; second, that gloomy thinking causes depression. According to the second theory, it is the depression that causes the chemical imbalance (not the other way around).
*The cognitive theories of depression are among the most clearly articulated and well-supported models of depression. According to these theories (e.g., Abramson, Metalsky, & Alloy, 1989; Nolen-Hoeksema, 1991), some individuals have a [[cognitive vulnerability]] that interacts with stress to produce depression. Specifically, people are vulnerable to depression because they have a tendency to generate interpretations of stressful life events (and [[dysphoric moods]]) that have negative implications for their future and for their [[self-worth]].
