The Mental Status Exam (MSE) is a psychiatry tool used to objectively, descriptively and thoroughly report a patient's mental state at the time of the clinical interview. It contains primarily information observed by the psychiatrist, not symptoms reported
by the patient, with a few exceptions.
The MSE is a part of every psychiatric clinical evaluation. It has a standard format just as the physical exam. It is interpreted in conjunction with the patient's history, physical exam and laboratory studies, leading to differential diagnosis.
Consideration is given to all aspects of mental functioning. The MSE is utilized both for initial diagnosis and for assessing the course of a disorder and its subsequent response to treatment.
