Psychotic disorders: describing the presentation

Describe the experiences and their effects

Psychotic presentations may include unusual beliefs, perception-like experiences, disorganized speech or behaviour, and changes in emotional expression or activity. Describe each finding rather than assuming that one experience accounts for the whole presentation.

Establish onset, persistence, distress and changes in functioning. Clarify the person’s understanding of the experiences and any uncertainty about them. The form of an experience and the explanation attached to it should be recorded separately.

Primary psychosis is not the only explanation

Psychotic symptoms can occur in mood disorders, neurocognitive presentations, substance-related states and other medical contexts. The relationship between symptoms, mood episodes, cognition and exposure history matters. A primary psychotic disorder cannot be inferred from hearing voices alone.

Longitudinal history and collateral observations may clarify the course and level of change. State what is known, what is reported and which alternative explanations have not yet been examined.

Culture and language are part of assessment

A belief or experience that seems unusual to the interviewer may be accepted in the person’s cultural or religious setting. Explore its meaning and the reference group before treating it as pathological. Unfamiliar metaphors and second-language expression can be misread.

For postgraduate discussion, compare the phenomenological description with the episode timeline and functional account. Consult the full classification reference for diagnostic requirements. The website does not provide an automatic diagnostic checklist or treatment recommendation.

For your next supervision discussion

Describe an unusual experience and the belief explaining it in separate sentences. Which contextual facts, cultural meanings and longitudinal findings would help distinguish the possible clinical interpretations?
