- Differentiating SZ
- Reliability

- Biological Explanation
- Genetics
- Genetic predisposition
- DRD2 & 2A Serotonin Receptor
- Evaluation
- Concordance Rates not 100%
- Gottesman - concordance rate for MZ-50% DZ-17% GenPop-1%
- Small sample size- MZ twins rare & only 1% of them may have SZ
- Diff to separate genetic& environmental- they share same environment
- Tienari
- Concordance Rates not 100%
- Genetic predisposition
- Dopamine Hypothesis
- SZ result of ^dopamine
- caused by: excess release of dopamine, excess of dopamine receptors, over sensitivity of dopamine receptors

- Diathesis Stress Model links genetic predisposition to SZ < life events
- Genetic vulnerability leads to biochemical abnormality
- Dopamine system
- Disrupted family comm. could trigger development of SZ
