How are depressive episodes usually triggered?
by a stressful event
What is the psychoanalytic explanation of depression?
suggests that depression occurs when significant losses evoke feelings associated with losses experienced in childhood
What is the genetic influence on mood disorders?
they tend to run in families; studies of identical twins reveal that genetic influence on mood disorders is strong
How is linkage analysis used in research of genetics in relation to depression?
researchers exam the chromosomes of both the affected and unaffected family members
studies that search for correlations between DNA variation and population traits
What are some biological reasons for depression?
depression may be caused by low levels of norepinephrine and seratonin
Drugs that alleviate mania, reduce ______________
How do drugs alleviate depression?
they increase the amount of norepinephrine or serotonin in the blood by blocking reuptake or inhibiting their chemical breakdown
What diet can predispose someone to depression?
a diet with lower levels of omega-3 fatty acids
Describe the brain’s of a person with depression?
the brains of depressed people tend to be less active, especially in an area of the left frontal lobe; in severly depressed patients, it may even be smaller in size
How do anti-depressant drugs that boost serotonin pmotoe recovery in the hippocampus
the hippocampus is important in processing memory and is vulnerable to stress related damage; drugs that boost serotonin may promote recovery by stimulating neurons in this area of the brain
Social-Cognitive perspective of depression
depression may be linked with self-defeating beliefs and negative explanatory style; some believes may arise from lerned helplessness
How do depressed people tend to explain failure?

the brain tissue has an excess of receptors of the neurotransmitter dopamine and drugs that block these receptors, have been found to decrease these symptoms; enlarged fluid-filled areas and a corresponding loss of cerebral tissue is present in those with schizophrenia; also an enlarged thalmus which accounts for difficulty in filtering sensory input
Drugs that interfere with receptors for the neurotrasnmitter ________ can produce negative symptoms of schizophrenia
Where do people with schizophrenia generally have high brain activity?
in the frontal lobe
What do some scientist contend are the reasons for brain abnormalites in schizophrenic patients?
low birth weight, oxygen deprivation, viral infections
What does the role of prenatal environment play into the risk of contracting schizophrenia?
the role of a prenatal environment is demonstrated by the fact that identical twins with the same placenta are more likely to experience schizophrenia (share the disorder)
