What is psychosis?

Psychosis is a state of mind in which a person loses touch with reality. Psychosis itself is not an illness. However, it can be a symptom caused by some mental illnesses. This symptom is called a psychotic episode. 



What causes psychosis?

Psychosis can be caused by:


  • Developing mental illness, such as schizophrenia or bipolar mood disorder


  • Excessive intake or abuse of alcohol and drugs


  • Reactions to emotional stress caused by severe personal trauma


  • Physical injury or the onset of another illness


  • A chemical imbalance in the brain


A chemical imbalance that interrupts the normal transmission of information from one part of the brain to another can result in many of the symptoms of psychosis.


    Types and Symptoms


    What are the early signs of a psychotic episode? 


    Early signs of a psychotic episode can be hard to detect but can include:


    • A drop in grades or job performance


    • Declining self-care and personal hygiene


    • Sleep disturbances


    • Changes in appetite


    • Difficulty concentrating and remembering things


    • Strong and inappropriate emotional responses, or none at all


    • Spending more time alone than usual and feeling withdrawn


    • Becoming suspicious of others


    • Feeling depressed, anxious, tense, irritable and/or angry


    • Confused thinking


    Everyday thoughts can become jumbled making it hard to remember things or follow a conversation. This affects a person’s ability to express themselves clearly.

    A combination of some of the signs above can indicate a person is experiencing the early stages of a psychotic episode.

    What are the symptoms of a psychotic episode? 


    Symptoms of a psychotic episode include:




    A delusion is a fixed or false belief that is not shared by others of similar culture and/or is inconsistent with the affected person’s social background. There are a variety of different types of delusions:


    1. Paranoid delusion

    A paranoid delusion involves believing you are being watched or singled out for some sort of harmful purpose, or are disliked.

    2. Grandiose delusion

    A grandiose delusion involves believing you have special powers.       

    3. Depressive delusion

    A depressive delusion is a belief of personal guilt or responsibility for some horrific event that you had no direct part in, or believing you are not fit to be with others.                                          

    4. Delusion of control

    A delusion of control involves believing an outside force is controlling your thoughts, feelings or actions.



    Hallucinations include seeing, hearing, smelling, tasting or feeling something that is not physically there. Hearing voices that no-one else can hear is the most common type of hallucination.


    Changed feelings

    During a psychotic episode, the affected person can experience an extreme change in the way they feel and express emotions.  

    There is sometimes a sense of flatness, often called blunted affect, where they feel less than they used to or experience an elevated mood.


    Changed behaviour 

    Someone experiencing a psychotic episode will often behave differently from normal.

    Treatment and Self-Care


    Can psychosis be treated? 

    Yes.  Early treatment is important as this can reduce the risk of a serious mental illness developing. 

    It is also important to recognise the signs of psychosis early, as the longer psychosis goes untreated the greater the disruption to the affected person and their whānau.


    How is psychosis treated? 


    Determining the best treatment will depend on factors such as how severe the symptoms are, how long they have been present and what the apparent cause is. 

    The symptoms of psychosis are best treated with medication, which can provide a rapid decrease in symptoms and relief for the affected person. 

    Whānau psychosis support, specialised types of counselling and psychotherapy can help reduce stress levels.


    Early psychosis intervention increases the chances of a rapid recovery.
