3. Much of the model remains biological

But clearly there are protective factors

The researchers looked at twins born in Denmark and found that if one identical twin had schizophrenia, the other twin (with the same genes) was also affected in about a third of cases. For non-identical twins, who only share on average half of their genes, this was true only in about 7% of cases. Based on these figures, the researchers calculated that 79% of the risk of developing schizophrenia was down to their genes.

While the findings suggest genes do play an important role in schizophrenia, this is only an estimate and the true picture is likely to be more complicated. Environmental factors clearly still have an influence on whether the person actually develops schizophrenia.
