mental status examination
Also written as: MSE — Mental Status Examination
A systematic assessment of a patient's psychological functioning, including appearance, behavior, cognition, and mood at the time of evaluation.
Full Definition
The Mental Status Examination is a structured clinical assessment that provides a snapshot of a patient's mental state during a specific encounter. It systematically evaluates multiple domains including appearance and behavior, speech, mood and affect, thought process and content, perceptual disturbances, cognition, insight, and judgment. The MSE is distinct from psychiatric history in that it focuses on observations made during the current examination rather than historical information. Results are documented using standardized terminology and help clinicians diagnose mental health conditions, assess capacity, and determine appropriate interventions. The MSE is a core component of psychiatric evaluations and is often required in legal and forensic contexts.
Usage
Usage note: Use 'mental status examination' (not 'mental state examination') in American clinical documentation. Can be abbreviated as MSE after first use.
