Document Summary
Very few causes in psychology because there are so many possibilities. Equifinality: a lot of different paths to get one outcome. Rates of mood disorders are very high in relatives of probands (the person with the disorder) Relatives of bipolar probands are more likely to suffer from unipolar depression. Relatives of probands are 2-3 percent more likely to have mood disorders than the general population. Adoption studies suggest that both nature and nurture are important. Identical twins: if one has a mood disorder, the other twin is 3 times as likely to have a mood disorder than the general public. Severe mood disorders seem to have a stronger genetic link. There is some variability between the sexes. Dopamine is closely related to our reward system. People with endocrine disorders have a stronger possibility of mood disorders. People with mood disorders have less suppression. Sleep disturbance is one of the flagstones of mood disorders.
