A mnemonic for the components of the mental state examination.

Appearance, behaviour, speech, mood, thought, perception, cognition, insight

Expansion

  • Appearance and behaviour: self-care, clothing, eye contact, rapport, psychomotor activity, abnormal movements
  • Speech: rate, rhythm, volume, quantity, form (flight of ideas, poverty of speech)
  • Mood and affect: mood is the subjective, sustained state reported by the patient; affect is the objective, observed and moment-to-moment. Note whether affect is reactive and congruent
  • Thought: form (loosening of associations, thought block), content (delusions, obsessions, preoccupations), and possession (thought insertion, withdrawal, broadcasting)
  • Perception: hallucinations (specifying modality), illusions, depersonalisation
  • Cognition: orientation, attention, memory, using a formal tool if indicated
  • Insight: does the patient recognise the experiences as abnormal and as illness, and do they accept the need for treatment
  • Risk: to self, to others, from others, and of neglect. Never omitted

The mood and affect distinction is the one most often confused: mood is the climate, affect is the weather.

Risk assessment should be explicit and specific, covering suicidal ideation with plans and intent, self-harm, harm to others including dependants, and safeguarding concerns.
