Mental Status Examination

The MSE is the psychiatric equivalent of the physical examination. It provides a structured, objective snapshot of a patient’s current cognitive and emotional status.


Domain Key Components
Appearance & Behavior Grooming, hygiene, posture, eye contact, agitation, or psychomotor retardation.
Speech Rate, volume, quantity, and fluency.
Mood & Affect Mood (subjective, e.g., “depressed”); Affect (objective, e.g., “flat,” “blunted,” “labile”).
Thought Process & Content Process (logic, flow, e.g., flight of ideas); Content (delusions, suicidal/homicidal ideation).
Perception Presence of hallucinations (auditory, visual) or illusions.
Cognition Level of consciousness, orientation, attention (e.g., serial 7s), memory, and executive function.


High-Yield Clinical Notes:

  • Observation: The MSE begins the moment you meet the patient.
  • Safety First: Always explicitly assess for suicidal or homicidal intent as part of the thought content evaluation.
  • Documentation: Use clear, descriptive language. Focus on what is observed (e.g., “patient avoids eye contact”) rather than using vague, subjective interpretive labels.
