Document Summary
Dsm only describes a pattern of symptoms, doesn"t offer explanation or suggest treatment. The etiology directs us to effective treatment methods. Etiology the cause, or set of causes of a disorder. Factors can be grouped into diff models, according to how they cause disorder. 4 models biological, behavioural, environmental etiological, cognitive. Twin studies determine whether a disorder has a genetic link. Further study is required to determine how specific genes cause disorder. Biomodel assumes that a psychological disorder results from malfunction in the brain (medical model) Concordance: 2 twins share a traits heritability can be estimated by comparing concordance rates of identical and fraternal twins. Specific genes: studies can be contradictory and inconclusive. Far from discovering how specific genes develop and maintain psychological disorders. Neurotransmitter activity is part of the etiology of psychopathology, but it is not the whole story.
