What happens in the brain of a depressed person?

Depression causes the hippocampus to raise its cortisol levels, impeding the development of neurons in your brain. The shrinkage of brain circuits is closely connected to the reduction of the affected part’s function. While other cerebral areas shrink due to high levels of cortisol, the amygdala enlarges.

What part of brain does depression affect?

Areas that play a significant role in depression are the amygdala, the thalamus, and the hippocampus (see Figure 1). Research shows that the hippocampus is smaller in some depressed people.
