Schizophrenia: symptoms, causes, care and support explained clearly

Schizophrenia is often misunderstood. It does not mean a split personality and it does not usually make a person violent. It is a long-term health condition that can be managed with the right care and support. This article uses information from the NHS, the World Health Organization (WHO) and the US National Institute of Mental Health.

1. Introduction

The NHS describes schizophrenia as a long-term mental health condition that causes a range of psychological symptoms and is often classed as a type of psychosis, which can make it hard for a person to tell their own thoughts from reality ^[1]. The National Institute of Mental Health says it affects how a person thinks, feels and behaves, and that people are usually first diagnosed between ages 16 and 30, after a first episode of psychosis ^[3].

WHO estimates that about 1 in 300 people worldwide live with schizophrenia. It is less common than many other mental disorders and tends to start earlier in men than in women ^[2].

2. Signs and symptoms

The NHS and WHO describe these symptoms ^{[1, 2]}:

• Hallucinations: hearing, seeing or sensing things that are not really there.
• Delusions: fixed false beliefs held despite evidence against them.
• Disorganised thinking and speech: muddled or irrelevant talk.
• Experiences of control: feeling that thoughts or actions are not your own or are placed there by others ^[2].
• Negative symptoms: reduced speech or emotional expression, loss of interest or pleasure, neglecting self-care and withdrawing from people.
• Difficulties with memory, attention and problem-solving ^[2].

The National Institute of Mental Health notes that gradual changes in thinking, mood and social functioning often appear before the first episode of psychosis ^[3].

3. Causes and risk factors

No single cause has been found. The NHS says most experts think it results from a mix of genetic and environmental factors, and that triggers can include a stressful life event or drug misuse ^[1]. WHO says psychosocial factors may influence when it starts and how it progresses, and that heavy cannabis use is linked to a higher risk ^[2].

4. Diagnosis

The NHS says there is no single test. Diagnosis usually follows an assessment by a mental health professional such as a psychiatrist ^[1]. If you notice symptoms in yourself or someone else, contact a doctor as soon as possible, because earlier treatment leads to better outcomes ^[1]. The National Institute of Mental Health also says delays between the start of symptoms and treatment can affect response and long-term health ^[3].

5. Treatment and care

Your psychiatrist decides on a plan to suit you. The sources describe these parts of care ^{[1, 2, 3]}:

• Medicines. The NHS says treatment typically includes antipsychotic medicines, and that taking medicine as prescribed helps ^[1]. Talk to your doctor before making any change to a medicine.
• Talking therapy. Cognitive behavioural therapy can help ^{[1, 2]}.
• Family and psychosocial support. WHO lists psychoeducation, which means learning about the condition, family interventions and rehabilitation such as life-skills training ^[2].
• Community care. WHO recommends care close to home, including primary care, community mental health and day centres, supported housing and employment support ^[2].
• Early psychosis programmes. The National Institute of Mental Health describes coordinated specialty care, a recovery-focused approach to early psychosis in which specialists, the person and the family decide together ^[3].

WHO notes that at least one in three people with schizophrenia can fully recover, while others have periods of worsening and improvement. The NHS says many people recover, although symptoms can return, and that treatment can reduce the effect of the condition on daily life ^{[1, 2]}. The National Institute of Mental Health says treatment can help people pursue school or work, gain independence and keep relationships ^[3].

6. Living well and avoiding relapse

The NHS says managing the condition well lowers the chance of severe relapses. Helpful steps include learning to recognise early warning signs of an episode, taking medicines as prescribed and talking openly with others. Support groups and charities can also help ^[1].

7. Physical health and rights

WHO states that people with schizophrenia die about nine years earlier than the general population, with causes that include heart, metabolic and infectious diseases ^[2]. WHO also says stigma is widespread and can limit access to health care, education, housing and work. It calls for person-centred, rights-based care in which people have a say in their treatment ^[2]. Fewer than one in three people with psychosis receive specialist care, so reaching out for help matters ^[2].

8. When to see a doctor

See a doctor as soon as possible if you or someone you know has symptoms such as hearing or seeing things that are not there, strong unusual beliefs, muddled thinking or withdrawal from daily life ^[1]. Do not wait, because earlier treatment leads to better outcomes ^[1]. If you are in distress or having thoughts of suicide or self-harm, reach out for help right now. In India, call Tele-MANAS on 14416. In the United States, call or text 988. You do not have to cope alone. In the United States, the National Institute of Mental Health also says to call 911 in life-threatening situations ^[3].

In an emergency, call your local emergency number (112 in India, 911 in the United States).

9. Conclusion

Schizophrenia is a serious but manageable condition, and many people recover with medicines, talking therapy and strong support from family and community. It is not a split personality and does not usually make a person violent. Seeking help early gives the best chance of good outcomes.
