Schizophrenia

Schizophrenia is a long-term (chronic) and serious mental illness that affects how you:

• think
• feel
• behave
• understand reality

People with schizophrenia may struggle with daily life, work and social activities.

Schizophrenia is the most common psychotic disorder in Australia. It usually starts in the late teenage years or early adulthood. It is more common in males than females.

Schizophrenia has a wide range of symptoms, including symptoms of psychosis. Psychosis is a condition where a person loses touch with reality.

Symptoms are grouped into 3 main types.

Positive symptoms

These are changes in thoughts or behaviours, such as:

• delusions — strong beliefs that aren't true or based on reality
• hallucinations — seeing or hearing things that aren't there
• unusual movements — such as repeated actions or staying still for a long time (catatonia)

Negative symptoms

Negative symptoms mean a person loses behaviours or emotions that most people have.

These may include:

• showing less emotion — having a blank face or a dull voice
• lack of motivation — not wanting to do daily activities
• less interest in things that used to be enjoyable
• avoiding people and social situations

Cognitive symptoms

These affect thinking and daily life, including:

• disorganised speech and thinking — talking in a way that jumps between topics or is hard to understand
• trouble focusing or paying attention
• forgetting things more easily

The exact cause of schizophrenia is unknown. It is believed to be caused by a mix of genetics, life experiences and brain chemistry.

• Genetics — having a close family member with schizophrenia may increase your risk.
• Life experiences such as pregnancy complications, infections, high stress, childhood trauma or social isolation may play a role.
• Brain chemistry — imbalances in brain chemicals, such as dopamine, serotonin and glutamate are linked to psychosis and thinking difficulties.

Drugs, such as marijuana, LSD or speed can make psychotic symptoms worse in people with schizophrenia. Sometimes, drug use may trigger schizophrenia.

Your doctor or mental health professional may diagnose schizophrenia through a mental health assessment.

To be diagnosed, you must have at least 2 or more of the following symptoms for at least one month:

• delusions
• hallucinations
• disorganised speech
• unusual movements
• negative symptoms

At least one of the symptoms must be delusions, hallucinations or disorganised speech.

The symptoms must also:

• make it hard for you to work, interact with other people or take care of yourself
• continue for at least six months (including the one month period)
• not be caused by substance abuse or another mental illness

A psychiatrist usually confirms the diagnosis and advises on the best treatment.

Schizophrenia has no cure, but treatment can manage symptoms and improve daily life. Early and regular treatment is important to prevent relapses.

Medicines

Medicine is the main treatment for schizophrenia. Antipsychotic medicines can reduce symptoms, such as hallucinations and delusions.

Some people develop side effects to medicine. This is why you should have regular check-ups with your psychiatrist or doctor.

Therapy and support

Psychological therapy can help people understand and manage their symptoms and learn new ways of coping. Options may include:

• cognitive behaviour therapy (CBT) — teaches ways to challenge delusions and cope with symptoms
• psychoeducation — teaches social skills to help with communication and daily activities
• family therapy — helps loved ones understand schizophrenia and provide support
• employment and education support — helps people return to work or study

Hospital and crisis treatment

Some people may need short-term hospital care if they:

• are at risk of harming themselves or others
• have severe hallucinations or delusions
• cannot take care of themselves

Living with schizophrenia can be challenging and is different for everyone. The right support can help you manage your condition.

Having family, friends and health professionals for support makes a big difference. A safe and stable home is important, especially during times when symptoms get worse.

Community services

Some people need help with daily tasks, such as cooking, cleaning or managing money. Community services can provide support.

People with schizophrenia have a higher risk of homelessness. Some may need special housing with care staff who assist with daily needs and medicines.

Lifestyle

Lifestyle changes can help you feel better. Try to:

• eat healthy
• stay active
• avoid drugs and alcohol

Schizophrenia cannot always be prevented, but you can lower the risk if you:

• take care of your mental health
• manage stress
• avoid using drugs
• get help early if you notice unusual thoughts or behaviours

Your doctor can refer you to a public mental health service or a private psychiatrist, psychologist or private hospital.
