What factors contribute to the development of schizophrenia?

Although the cause of schizophrenia is unknown, it is assumed to be linked to the following factors:

1. Genetics

While there is no one cause for schizophrenia, scientists believe it has a significant hereditary component, specifically an inherited chemical imbalance in the brain.

Schizophrenia is caused by a combination of genes inherited from both parents: If a parent is schizophrenia, a child has a 10 to 15% chance of being schizophrenic; if a sibling is schizophrenic, a child has a 7 to 8% chance of becoming psychotic. The risk increases considerably if more than one family member has the disease.

2. Environmental stress caused by pregnancy

Despite the absence of proof, some experts believe that a child’s schizophrenia may be linked to certain environmental factors that affect the mother during pregnancy, such as:

-drugs or alcohol abuse
-exposure to specific hormonal or pharmacological agents
-getting infected with or being exposed to specific viruses
-extreme anxiety
-nutritional adequacy
