1. Understanding psychosis


What causes psychosis?

It is not known what exactly causes mental health problems. However, a combination of biological, psychological and social factors can influence their development, including:

    the way a person’s brain works
    difficulties during childhood
    life events

Symptoms can emerge in response to stress, substance use or social changes. The combination of biological vulnerability and stress, which can lead to psychosis, is called the stress–vulnerability model.
