Psychosis

Psychosis is a condition that affects a person’s mind and causes changes to the way that they think, feel and behave. A person who experiences psychosis may be unable to tell the difference between reality and their imagination.

People who experience psychosis are sometimes referred to as psychotic. They may experience:

  • Hallucinations: where they see or hear things that are not there.
  • Delusions:  where they believe things that are untrue.

Psychosis is not a condition in itself; it is a symptom of other conditions. The most common cause of psychosis is a mental health condition, such as schizophrenia or bipolar disorder (manic depression).

Psychosis can also be triggered by physical conditions, such as Parkinson's disease, or as a result of drug or alcohol misuse.

We have specialist teams to support people who are experiencing their first episode of psychosis.  By starting early, these teams can often help people to recover and manage their mental wellbeing.

We also support people through our Adult Mental Health Services and through rehabilitation services for those who have long-term mental health issues.
