- Stammering
- Rapid and pressured speech
- Akathisia (excessive motor activity) shown by wringing of hands, inability to sit still
- Bradykinesia (psychomotor retardation) is shown by the slowing of physical and emotional reactions
- Catatonia (immobility with muscular rigidity or inflexibility)
- Slowness and loss of spontaneity in movement
- Language, memory, and orientation:
- Verbal or written communication skills
- Recall past events
- Aphasia (an inability or impaired ability to understand or produce speech, as a result of brain damage)

- Reaction evoked in the examiner:
- Feelings aroused in the examiner by the patient
- Appearance:
- A detailed cognitive ability testing:
- Gnosia (the ability to name objects and their function)
- Praxis (motor planning to perform a task)
- Prosody (a striking feature of the speech that is interpreted as stress or intonation)
- Visuospatial proficiency (ability to perceive and manipulate objects and shapes in space)
- Specific testing: Based on the physician’s judgment, clinical examination or screening tools can be used that have varying sensitivity and specificity for neurologic and psychiatric disorders, but none are diagnostic for any mental status disorder.
- Addenbrooke's Cognitive Examination-Revised: A 20-minute test to assess attention, executive functioning, language, memory, orientation, and visuospatial proficiency.
- Mini-Mental Status Examination: To assess a wide range of domains, including attention, language, memory, orientation, and visuospatial proficiency.
- Mini-Cog: A brief screening tool of five minutes or less to measure executive functioning, memory, and visuospatial proficiency.
- Montreal Cognitive Assessment: A brief screening tool of 10 minutes or less to assess attention, executive functioning, language, memory, and orientation.
What is a mental status examination?
Mental status examination (MSE) is a structured and systematic assessment of the patient's behavioral and cognitive functioning used as an important diagnostic tool in both neurological and psychiatric diseases.
MSE is useful in helping differentiate between several systemic conditions, neurologic and psychiatric disorders ranging from delirium and dementia to bipolar disorder and schizophrenia.
5 categories of mental status examination
To assess the patient’s mental status appropriately, it is important to have some understanding of the factors of the patient, such as their:
- Age
- Social, cultural, and native language
- Educational background
A mental status examination can be divided into the following five major categories:
- General appearance
- Emotions
- Thoughts
- Cognition
- Judgment and insight
What is the purpose of mental state examination?
Mental status examination (MSE) is a component of all medical examinations and may be viewed as the psychological equivalent of the physical examination that can help identify the presence and severity of several mental health conditions and the risk a patient poses to themselves or others.
MSE aims to evaluate, quantitatively and qualitatively, a range of mental functions and behaviors at a specific point in time that provides important information for diagnosis and assessment of the disorder’s course and response to treatment.
MSE is interpreted along with the presenting history, physical examination, and laboratory and radiologic findings.
