The 2 main symptoms of psychosis are:
- hallucinations – where a person hears, sees and, in some cases, feels, smells or tastes things that do not exist outside their mind but can feel very real to the person affected by them; a common hallucination is hearing voices
- delusions – where a person has strong beliefs that are not shared by others; a common delusion is someone believing there’s a conspiracy to harm them
The combination of hallucinations and delusional thinking can cause severe distress and a change in behaviour.
Experiencing the symptoms of psychosis is often referred to as having a psychotic episode.
