PSYB32H3 Chapter Notes - Chapter 8: Cognitive Therapy, Amygdala, Prefrontal Cortex
Document Summary
Formal diagnostic listings of mood disorders: diagnosis of depression, major depressive disorder (mdd): requires the presence of five of the following. Genetic vulnerability: used twins, family, and adoption methods to do the research, bipolar disorder is one of the most heritable of disorder. Neurochemistry, neuroimaging, and mood disorder: the most-studied neurotransmitters have been norepinephrine, serotonin, and dopamine, there are 2 types of drugs which are effective in reliving depression, tricyclic drugs. A group of antidepressant medications which prevent some of the reuptake of norepinephrine, serotonin, and/or dopamine by the presynaptic neuron: monoamine oxidase inhibitors. Antidepressant that keep the enzyme monoamine oxidase from deactivating neurotransmitters, thus increasing the levels of serotonin, norepinephrine, and/or dopamine in the synapse. Similar to tricyclic drugs: selective serotonin reuptake inhibitors (ssris, newer antidepressant drugs, treat unipolar depression, the amygdala, hippocampus, prefrontal cortex, and the anterior cingulate are the main brain structures implicated in mdd and bipolar disorder. Current therapies are both psychological and biological.
