Schizophrenia is caused by bad parenting.

Schizophrenia is caused by distinct genetic and environmental risk factors and is not caused directly by poor parenting. It is a prevalent misconception that poor parenting or tough relationships cause schizophrenia. This stereotype could possibly be falser. There are various genetic origins of schizophrenia. Each of them has a minor influence on the overall progression of the illness. Severe childhood stress or trauma, as well as infections that activate the immune system, are all risk factors for developing schizophrenia.

A minor loss on chromosome 22 is another genetic risk factor. All of a person's genetic information is stored on chromosomes. A minor loss on chromosome 22 can predispose a person to not just schizophrenia but also cardiac, immunological, and developmental disorders (cleft palate). There may be certain environmental and psychological elements that contribute to the development of schizophrenia, but they must be objectively proven.
