Psychosis

Also called Psychotic episode

Psychosis is when a person loses some contact with reality. This might involve seeing or hearing things that other people cannot (hallucinations) or believing things that are not true (delusions). It can be a symptom of conditions such as schizophrenia or bipolar disorder, or be triggered by stress, drugs, alcohol, lack of sleep or a physical illness.

What it is

Early help makes a difference. Many areas have specialist early intervention teams for people having their first episode.

Treatment usually includes antipsychotic medicines, talking therapies and social support.

Common signs

  • Hearing voices or seeing things others do not
  • Strong beliefs that others do not share
  • Muddled thinking or speech
  • Feeling very suspicious or fearful
  • Withdrawing from others
  • Changes in sleep and self-care

How it is usually diagnosed

  • Assessment by a mental health professional
  • Tests to rule out physical causes, such as blood tests or a brain scan

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Mental health assessment letters
  • Care plans
  • Medicine lists and blood test monitoring
  • Discharge letters

Questions to ask your doctor

  • What might have caused this episode?
  • What are the side effects of the medicine?
  • Who do I contact if symptoms come back?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Thoughts of harming yourself or others, or a person who is very distressed or unsafe: call 112
