10 psychosis facts and figures

In this article we will describe 10 facts and figures about psychosis; focusing on its symptoms, causes, and treatment.

Psychosis is when people lose contact with reality. This might involve seeing or hearing things that other people cannot see or hear (hallucinations) and believing things that are not actually true (delusions).

Let’s start with the basics.

1. Definition

Psychosis is a mental health condition characterised by a disconnection from reality. It can involve hallucinations (seeing or hearing things that aren’t there), delusions (false beliefs), and impaired insight.

2. Symptoms

Common symptoms include hallucinations, delusions, disorganised thinking, and grossly disorganised or abnormal motor behaviour. Negative symptoms, such as reduced emotional expression and lack of motivation, may also be present.

3. Causes

Causes of psychosis include:

  • Schizophrenia
  • Bipolar disorder
  • Depression
  • Substance abuse
  • Severe stress or trauma
  • Medical conditions affecting the brain (e.g. brain tumours, cerebral lupus (SLE), infections).
4. Prevalence

Psychosis affects approximately 3% of people at some point in their lives. Schizophrenia, a common psychotic disorder, affects about 1% of the global population.

5. Age of onset

Psychosis typically emerges in late adolescence to early adulthood, though it can occur at any age. The average age of onset for schizophrenia is late teens to early 20s for men, and late 20s to early 30s for women.

6. Early signs

Early warning signs of psychosis can include a drop in grades or job performance, difficulty thinking clearly, paranoia, social withdrawal, and a decline in personal hygiene.

7. Diagnosis

Diagnosing psychosis involves a comprehensive evaluation by a mental health professional, including a detailed history, mental status examination, and neuroimaging (e.g. CT scan) and blood tests to rule out other conditions.

8. Treatment

Treatment typically includes antipsychotic medication, which help reduce the severity of symptoms, and psychotherapy, such as cognitive-behavioral therapy (CBT), which helps individuals manage their symptoms and improve functioning.

9. Complications

People with a history of psychosis are more likely to:

  • Have drug or alcohol misuse problems, or both. Some people use drugs and alcohol as a way of managing the symptoms of psychosis. But, it can make symptoms worse or cause other problems
  • Self harm or commit/attempt/suicide.
10. Prognosis

The prognosis for psychosis varies. With early and appropriate treatment, many individuals can manage their symptoms effectively and lead productive lives. However, untreated psychosis can lead to significant impairment and a poorer outcome.

Stigma and support

Stigma surrounding psychosis can hinder individuals from seeking help. Support from family, friends, and mental health professionals is crucial for recovery. Education and awareness can help reduce stigma and improve outcomes for those affected.
