Document Summary
Continuum with normality almost everyone gets depressed at some point during their life. Prevalence of major depression 13% of men and 20% of women. #4 disability among those age 5+ (world health organization) cost = billion/year in u. s. Not restricted to any age group but common among adolescents and adults. Mania = extreme happiness, energy, self-confidence, invincibility, loss of inhibition, recklessness, grandiosity, drug abuse. Mz twins: 30-40% concordance for major depression (60% for bipolar) No genetic connection between depression and bipolar disorder. Zoloft, prozac, etc. are ssri (selective serotonin reuptake inhibitors) Only help about 2/3 of people, takes weeks to take effect. Other evidence that dopamine and norepinephrine are involved. 21% of women vs. 13% of men will experience major depressions. Genetic and hormonal versus social role explanations. Internal/global/stable explanatory style -> stress -> learned helplessness (aka depression) As we saw with schizophrenia, the causes of mental illness are seldom unitary.
