Acute psychosis is a state in which a person can be found at a given moment; a person in that state has often lost contact with reality partially or completely.

Symptoms and causes

Symptoms and causes


  • Delusions= a type of imaginary idea that one has about oneself; the person cannot distinguish between what is real and what is not.
  • Hallucinations= things you perceive that are not really there (e.g. hearing voices or seeing ghosts)
  • Confusion: coherent conversations can hardly take place, forgetting what one is doing, etcetera.

How do you recognise that someone has acute psychosis?

The person often has a confused way of talking, mixes up things and speaks gibberish. Usually the answers to questions are short. He/she may sometimes adopt a petrified posture that virtually does not change. There is hardly any eye contact, the person usually looks to the side of you. A sort of suspicion/watchfulness.
