Monoamine Theory of Depression

Abnormalities within the monoamine systems causative of depression - often too low amounts of the one of these NTs:
◦ Serotonin
◦ Norepinephrine
◦ Dopamine

5

Inflammatory Theory of Depression

Low levels of chronic inflammation from either active illness or persistent heightened level of corticosteroids from “stress” produce a toxic inflammatory milieu where neurodegeneration increases and neurogenesis is inhibited.

6

What IL might be associated with depression?

IL-6 - also associated with increased risk of heart disease and Alzheimer's

7

Structural Theory of Depression

Depression is caused by abnormal changes in brain areas that can be identified premorbidly and are exacerbated in active illness - atrophy of the prefrontal cortex, amygdala, and hippocampus suggestive

8

Network Hypothesis of Depression

It is not specifically an altered brain area that causes depression but aberrancies in the tracts between areas. Diffusion tension imagery has revealed white matter abnormalities in the tracts between the medial prefrontal cortex, amygdala, and hippocampus.
