in terms of cause and effect, why might the theory that a pathogenic, or unhealthy, family is the root cause of schizophrenia be reversed?

According to this theory, the familial schizophrenia may be triggered by environmental conditions and therefore it is reversible.

Explanation:

The cause and effect theory states that the environmental conditions play key roles for the development of a specific state, thereby these factors can be manipulated to reverse their adverse effects on certain diseases. In this regard, it has been interestingly shown that a healthy lifestyle can reverse and prevent cognitive diseases as schizophrenia disorder.
