What are the causes of schizophrenia?
<|assistant|>
The cause of schizophrenia is not fully understood, but it is known to be a complex neurobiological disorder that is usually attributed to a combination of environmental, genetic and neural factors. Increasing evidence suggests that the disorder is often linked to abnormalities in certain regions of the brain. There is also some evidence that certain life events such as stress or poor parental care in childhood can lead to a higher risk of developing the disorder.
