The medical model

Explanation:

The medical model refers to the way psychiatrists view the signs and symptoms of schizophrenia.

This model states that mental disorders are brain diseases and relies on pharmacological treatment to cure them.  It explains the origin of the diseases based on physiological factors.

In this example, Gina and Tina are identical twins, however only one of them has been diagnosed with schizophrenia. Since schizophrenia tends to run in families, we could explain this difference by using the medical model stating that the origin of schizophrenia is in the brain and Gina was exposed to a different set of experiences than her sister, which in turned triggered the Schizophrenia, which had its origin on physiological factors.
