10. Explain why a multi-factoral model schizophrenia may help in explaining the disorder. Remember there is still no cure for this disease, and the

causes are not known either. The multi-factoral model Illustrates how several biological and

psychological factors may interact in the development of the disorder. In this model, genetic factors create a vulnerability, or

susceptibility, to schizophrenia. Among people who are genetically vulnerable, other factors,

such as trauma during birth, may lead to brain injury and the subsequent development of schizophrenia.

Once the disorder develops, its course may be negatively affected by the family environment or stress. Another factor may be the maturing of the frontal cortex.

The model also suggests that environmental factors alone are not enough to lead to the development of schizophrenia. Thus, people who are not genetically vulnerable are unlikely

to develop the disorder.
