| | The catecholamine theory of mood was suggested by Schildraut and Kety. | | | Tetrabenazine (TBZ) depletes catecholamines (NA and DA) and was used to test the Catecholamine Theory of Mood. | | | The catecholamine theory does not distinguish between the roles of DA and NA in depression. |

| | Catecholamine - Wikipedia, the free encyclopedia |
| | Catecholamines cause general physiological changes that prepare the body for physical activity (fight-or-flight response). | | | Some drugs, like tolcapone (a central COMT-inhibitor), raise the levels of all the catecholamines. | | | High catecholamine levels in blood are associated with stress, which can be induced from psychological reaction or environmental stressors such as elevated sound levels or intense light. |

| | Depression: Beyond the catecholamine theory of mood |
| | I have adopted an historical approach beginning with Schildkraut's 1965 Catecholamine Theory of Mood (this theory was covered earlier in the course), before discussing work on biological markers which revealed the importance of serotonin (5-HT) in depression. | | | The CA theory of mood dominated research in this area for several decades. | | | Serotonin (5-HT), and a possible interaction between 5-HT and NA, may play an important role in mood. |
