Psychosis describes when a person loses contact with reality and experiences severe instability (unpredictable changes) in thinking, emotions, and behaviour. It can make people have strange ideas and behave oddly. The main psychotic disorders are schizophrenia and drug-induced psychosis.
Psychosis can have physical (the body), psychological (the mind), and behavioural (the way people act) signs and symptoms.
The physical signs may include:
The psychological signs may include:
The behavioural signs may include:
It is important to be are aware that the signs and symptoms of psychosis can be different for different cultures. For example, in some Aboriginal and Torres Strait Islander communities, being visited by the spirit of a loved one who has passed away or hearing their voice is normal, so it's different to psychosis. In other cultures, these experiences may be signs or symptoms of psychosis.

There is no single cause for psychosis - it is normally the result of a combination of factors. Some people are more at risk of developing a psychotic disorder because of:
There are other factors that can slightly increase the chances of someone developing a psychotic disorder. These factors include having complications at the time of birth or a head injury.
Information about how many Aboriginal and Torres Strait Islander people have a psychotic disorder is not available, but hospitalisation information from 2008-09 shows that Aboriginal and Torres Strait Islander adults were four times more likely to be hospitalised for schizophrenia and delusional disorders than were other Australians.
Research has also found that psychotic disorders are more common among young adult Aboriginal men, especially those who also have substance misuse problems, intellectual impairments, and diabetes.
When helping someone who has a psychotic disorder, it is important that you:
People who are experiencing signs of a psychotic disorder will sometimes try and keep these physical, psychological, and behavioural changes a secret and not talk about them. If you are talking about these changes with the person, it is important to be caring, non-judgemental, and respectful. You should find a quiet place to talk and ask questions, and use words that are easy to understand.
Other ways to help someone who may have a psychotic disorder is to encourage them to:
