Mental State Examination
Introduction to Mental Status Examination
Mental status examination (MSE) is a clinical assessment tool mental health
professionals use to evaluate a patient's mental state, including their behaviour,
mood, thought processes, and cognitive functioning. It is typically conducted during
the initial assessment and throughout treatment to monitor changes in the patient's
mental status.
The MSE involves systematic observation and evaluation of various aspects of the
patient's mental state, including appearance, behaviour, speech, thought content,
mood, and cognition. The clinician may also assess the patient's insight, judgment,
and overall level of functioning.
The MSE aims to help the clinician diagnose mental health conditions, develop an
appropriate treatment plan, and monitor the patient's progress over time. It is an
essential tool for clinicians working in various settings, including hospitals, clinics,
private practices, and mental health facilities.
Components
General Appearance and Behavior
General Appearance
1. Physique and body habitus (built): Observe the patient's body shape and
size, including their height, weight, and build.
2. Physical appearance (height, weight): Record the patient's height and
weight, as well as any relevant physical features or abnormalities.
3. Looks comfortable/uncomfortable: Observe whether the patient appears
comfortable or uncomfortable, restless, or agitated.
4. Physical health: Evaluate the patient's overall physical health, including any
visible signs of illness, injury, or disability.
5. Grooming, hygiene, self-care: Assess the patient's level of grooming,
hygiene, and self-care. Observe if they are well-groomed, have good
personal hygiene, and appear to take care of themselves.
6. Dressing (adequate, appropriate): Evaluate the patient's choice of clothing,
whether it is adequate for the weather and situation and appropriate for the
occasion.
7. Facies (non-verbal expression of mood): Observe the patient's facial
expressions, noting any signs of distress, anxiety, depression, or other

emotions.
8. Effeminate/masculine on MSE: It is not appropriate to assess the patient's
gender identity or expression during the mental status examination as it is
not relevant to their mental health status. It is important to use inclusive and
respectful language and avoid making assumptions based on the patient's
appearance or behavior.
Attitude towards examiner
1. Cooperation/guardedness/evasiveness/hostility/combativeness/haughtiness:
Observe the patient's behaviour towards the examiner. Do they cooperate,
seem guarded, evasive, hostile, combative or haughty?
2. Attentiveness: Observe the patient's level of attentiveness during the
interview. Are they actively engaged in the conversation or appear distracted
or disinterested?
3. Appears interested/disinterested/apathetic: Note the patient's level of
interest in the interview. Do they appear interested in what is being
discussed, or do they seem disinterested or apathetic?
4. Any ingratiating behaviour: Observe if the patient displays any ingratiating
behaviour, such as excessive flattery or attempts to please the examiner.
5. Perplexity: Note if the patient seems perplexed or confused by the questions
or conversation during the examination.
It is important to note that a patient's attitude towards the examiner can be
influenced by various factors, such as their cultural background, personality
traits, and mental health condition. The examiner should use a non-judgmental
and empathetic approach to establish rapport and build trust with the patient.
Comprehension, Gait and posture
Accessing comprehension, whether it is intact or impaired, is a critical aspect of
a mental status examination (MSE). Here are some guidelines for assessing
comprehension:
1. Ask the patient to follow simple commands: Ask the patient to perform tasks
such as "Close your eyes," "Point to the ceiling," or "Give me your right
hand." This will give you an idea of their ability to understand and carry out
simple instructions.
2. Ask the patient to repeat a sentence: Choose a simple sentence, such as
"The cat sat on the mat," and ask the patient to repeat it back to you. This
will assess their ability to understand and recall information.
3. Ask the patient to answer questions: Ask the patient questions about their
personal information, such as their name, age, and address. You can also
Mental State Examination
2
ask questions about current events or general knowledge to assess their
comprehension.
4. Use visual aids: If the patient is struggling to understand verbal instructions,
you can use visual aids such as pictures or diagrams to help them.
If the patient's comprehension is impaired, you should try to determine the
extent of the impairment. You can do this by asking more complex questions or
tasks, such as asking the patient to follow multi-step instructions or to explain a
concept in their own words. Additionally, you can assess their reading and
writing abilities to determine the level of impairment further. It is important to
note whether the impairment is partial or complete, as this can help inform
treatment and management strategies.
To assess gait and posture, a healthcare provider may observe the patient while
they are walking, standing, sitting, or lying down. They may look for
abnormalities in the way the patient moves or positions themselves, such as
limping, slouching, or leaning to one side. The provider may also assess the
patient's balance, coordination, and muscle strength.
Abnormal gait and posture can be caused by a variety of factors, including
injury, disease, or neurological conditions. A healthcare provider may refer the
patient for further testing or imaging to determine the underlying cause of any
abnormalities observed during the assessment.
Motor activity
To assess motor activity and related signs during a Mental State Examination
(MSE), a healthcare provider may observe the patient's movements and
behavior during the assessment. Here are some ways that the provider can
access specific signs:
Increased/decreased motor activity: The provider can observe the patient's
level of activity, including how much they move and whether they are
agitated or lethargic. They may ask the patient to perform simple
movements or tasks to further assess motor function.
Excitement/stupor: The provider can observe the patient's level of
responsiveness to their surroundings. Excitement may be characterized by
restlessness, agitation, or over-activity, while stupor may involve reduced
responsiveness, slowed movements, or a lack of activity.
Abnormal involuntary movements (AIMs): The provider can observe the
patient for any involuntary movements such as tics, tremors, or akathisia.
They may ask the patient to perform specific tasks to see if these
movements are present during different activities.
Mental State Examination

Restlessness/ill at ease: The provider can observe the patient for any signs
of restlessness, such as fidgeting or pacing, or signs of being ill at ease,
such as avoiding eye contact or exhibiting anxious behavior.
Catatonic signs: The provider can observe the patient for any abnormal
motor behaviors such as mannerisms, stereotypies, posturing, or waxy
flexibility. They may ask the patient to perform certain movements or
postures to assess these behaviors.
Conversion and dissociative signs: The provider can observe the patient for
any signs of pseudoseizures or possession states, such as sudden loss of
consciousness, unusual movements, or apparent alteration of
consciousness or identity.
Social withdrawal, Autism, compulsive acts, rituals or habits, reaction time:
The provider can ask the patient specific questions to assess their level of
social engagement or their tendency to engage in compulsive or ritualistic
behaviors. They may also ask the patient to perform specific tasks to assess
their reaction time or motor function.
It's important to note that the presence or absence of these signs can be
indicative of underlying mental or physical health conditions, and healthcare
providers may use these observations to inform a diagnosis or treatment plan.
Social manners and non-verbal behaviour
Assessing social manner and non-verbal behavior can be done through a
Mental State Examination (MSE) which involves observing and evaluating the
patient's behavior during the interview. Here are some ways to assess social
manner and non-verbal behavior:
1. Increased or decreased behavior: Observe if the patient's behavior is
heightened or subdued compared to what is expected in the given situation.
2. Inappropriate behavior: Assess if the patient's behavior is appropriate or not
for the given context. For example, laughing during a serious discussion can
be considered inappropriate.
3. Eye contact: Evaluate the patient's eye contact during the interview. Eye
contact can vary from gaze aversion, staring vacantly, staring at the
examiner, hesitant eye contact, and normal eye contact.
To assess eye contact, ask the patient to maintain eye contact with you while
you ask questions. Observe how they maintain eye contact and whether they
break it frequently or avoid it altogether.
Additionally, you can also ask open-ended questions and observe their reactions
to assess their non-verbal behavior. Pay attention to their body language, facial
expressions, and tone of voice.

It's important to remember that the interpretation of social manner and nonverbal behavior should be done with consideration to cultural and personal
differences. It's also important to maintain a non-judgmental attitude while
assessing and interpreting the patient's behavior.
Rapport
Assessing rapport between the clinician and the patient can be done through
observation during the Mental State Examination (MSE). Here are some ways to
assess rapport:
1. Observation of verbal and non-verbal behavior: Assess how the patient
responds to the clinician's questions, whether they are open or closed off,
whether they maintain eye contact or avoid it, and how they use their tone of
voice.
2. Empathy: Assess whether the clinician is able to show empathy towards the
patient and their situation, and whether the patient perceives this empathy.
This can be done by observing the tone of the clinician's voice, the words
they use, and the way they respond to the patient's feelings.
3. Establishment of a working relationship: Assess whether the clinician is able
to establish a working relationship with the patient. This can be done by
observing the level of trust and confidence that the patient displays towards
the clinician.
To assess rapport, the clinician can begin by introducing themselves to the
patient and establishing a safe and comfortable environment for the interview.
They can use open-ended questions and active listening skills to encourage the
patient to open up and express their thoughts and feelings. Additionally, the
clinician can use reflection and validation to show empathy towards the patient.
It's important to note that rapport can take time to establish, and it may be more
challenging with some patients than others. It's also important to maintain a nonjudgmental attitude and to be respectful of cultural and personal differences.
Hallucinatory behaviour
Assessing hallucinatory behavior during the Mental State Examination (MSE)
involves observing the patient's behavior, including their verbal and non-verbal
communication, in response to auditory or visual hallucinations. Here are some
ways to assess hallucinatory behavior:
1. Observation of verbal and non-verbal behavior: Observe the patient's facial
expressions, body movements, tone of voice, and the content of their
speech.
2. Assessment of the context: Determine if the patient's behavior is appropriate
for the context of the interview or if it seems to be a response to internal
Mental State Examination
5
stimuli.
3. Assessment of the patient's insight: Determine whether the patient
recognizes that their experiences are not based in reality.
Some specific behaviors that may indicate hallucinations include:
1. Smiling or crying without reason: Observe whether the patient displays
emotions that seem unrelated to the conversation or situation at hand.
2. Muttering or talking to self: Observe whether the patient appears to be
engaged in a conversation with someone who is not present.
3. Odd gesturing: Observe whether the patient displays gestures or
movements that seem to be in response to internal stimuli.
To assess hallucinatory behavior, the clinician can ask the patient about their
experiences and whether they are hearing or seeing things that others cannot.
The clinician should also inquire about the content of the patient's experiences
and whether they are distressing or interfering with their daily functioning. It's
important to maintain a non-judgmental attitude and to be respectful of the
patient's experiences. If the patient is experiencing distressing hallucinations,
the clinician may need to refer them for further evaluation or treatment.
Speech
Rate and quantity of speech
Assessing rate and quantity of speech during the Mental State Examination
(MSE) involves observing the patient's speech and communication patterns.
Here are some ways to assess rate and quantity of speech:
1. Observation of verbal behavior: Observe the patient's verbal behavior,
including whether they are speaking or not, and if they are, the quantity and
rate of their speech.
2. Assessment of the context: Determine if the patient's speech is appropriate
for the context of the interview.
3. Assessment of the patient's insight: Determine whether the patient
recognizes that their speech patterns are not based in reality.
Some specific behaviors that may indicate changes in rate and quantity of
speech include:
1. Speech present or mutism: Observe whether the patient is speaking or not.
2. Spontaneous productivity: Assess the patient's ability to initiate speech on
their own.
3. Rate of speech: Observe whether the patient's speech is rapid or slow.
Mental State Examination

4. Pressure of speech: Assess whether the patient's speech is pressured,
meaning that they are speaking quickly and with a sense of urgency.
5. Poverty of speech: Observe whether the patient is speaking in short,
concise sentences with minimal elaboration or detail.
To assess rate and quantity of speech, the clinician can ask the patient openended questions and observe their responses. The clinician can also ask the
patient to describe their thoughts and feelings and observe their ability to
express themselves. It's important to maintain a non-judgmental attitude and to
be respectful of the patient's communication patterns. If the patient is
experiencing changes in speech that are concerning, the clinician may need to
refer them for further evaluation or treatment.
Volume, tone and pitch of speech
MSE typically stands for "mental status examination," which is a clinical
assessment tool used by mental health professionals to evaluate a patient's
current mental state. When it comes to assessing volume, tone, and pitch of
speech during an MSE, here are some guidelines:
Volume:
Increased volume: If the patient's speech is loud, yelling, or shouting, you
would describe it as "increased volume" or "loud."
Decreased volume: If the patient's speech is soft or whispering, you would
describe it as "decreased volume" or "quiet."
Normal volume: If the patient's speech is at a normal volume, you would
describe it as "normal volume."
Tone:
Increased tone: If the patient's speech has an exaggerated or heightened
emotional quality, you would describe it as "increased tone" or "emotional."
Decreased tone: If the patient's speech is flat or lacking in emotional
expression, you would describe it as "decreased tone" or "flat."
Normal tone: If the patient's speech has a normal emotional quality, you
would describe it as "normal tone."
Pitch:
High pitch: If the patient's voice is high-pitched or squeaky, you would
describe it as "high pitch."
Low pitch: If the patient's voice is low or monotone, you would describe it as
"low pitch."

Normal pitch: If the patient's voice has a normal pitch, you would describe it
as "normal pitch."
It's important to note that these descriptors are not mutually exclusive, and a
patient's speech may exhibit more than one quality at the same time. For
example, a patient may speak loudly with an increased emotional tone and a
high pitch. The key is to observe and describe the patient's speech as
accurately and objectively as possible.
Flow and rhythm of speech
Assessing the flow and rhythm of speech during an MSE requires careful
observation and attention to detail. Here are some guidelines for assessing
specific aspects of speech:
Flow and Rhythm:
Smooth: If the patient's speech flows smoothly, without interruptions or
pauses, you would describe it as "smooth."
Hesitant, blocking: If the patient's speech is interrupted by frequent pauses,
hesitations, or blocks, you would describe it as "hesitant" or "blocking."
Dysprosody: If the patient's speech is characterized by a disturbance in the
rhythm, timing, or melody of speech, you would describe it as "dysprosody."
Stuttering/Stammering/Cluttering:
Stuttering: If the patient repeats or prolongs sounds or words, or
experiences involuntary pauses, you would describe it as "stuttering."
Stammering: If the patient has difficulty initiating speech or experiences
frequent repetitions or hesitations, you would describe it as "stammering."
Cluttering: If the patient's speech is characterized by rapid or irregular
speech patterns, with words and phrases overlapping or blending together,
you would describe it as "cluttering."
Accent:
Any accent: If the patient speaks with an accent, you would note the type of
accent and any impact it may have on communication.
Thought and Language Process:
Circumstantiality: If the patient's speech is characterized by excessive
detail, irrelevant information, or a tendency to digress or get off topic, you
would describe it as "circumstantial."
Tangentiality: If the patient's speech is characterized by frequent tangents,
or a tendency to stray from the topic at hand, you would describe it as
"tangential."

Verbigeration: If the patient's speech is characterized by frequent repetition
of words or phrases, you would describe it as "verbigeration."
Stereotypies: If the patient's speech is characterized by repetitive or
ritualistic patterns of speech, you would describe it as "stereotypies."
Flight of Ideas: If the patient's speech is characterized by rapid shifts in topic
or ideas, with minimal connection between them, you would describe it as
"flight of ideas."
Clang associations: If the patient's speech is characterized by the use of
words that sound alike but have no connection in meaning, you would
describe it as "clang associations."
Remember, when assessing the flow and rhythm of speech, it's important to be
objective and descriptive in your observations, avoiding judgments or
assumptions about the patient's speech patterns.
Mood and Affect
Mood
Assessing mood during an MSE involves both subjective and objective
measures, and it's important to evaluate the quality, stability, reactivity, and
persistence of the patient's mood. Here are some guidelines for assessing
specific aspects of mood:
Quality of Mood:
General warmth, euphoria, elation, exaltation, ecstasy: If the patient's mood
is characterized by a general feeling of happiness, excitement, or joy, you
would describe it as "warm," "euphoric," "elated," "exalted," or "ecstatic."
Anxious, restless: If the patient's mood is characterized by a general feeling
of anxiety, nervousness, or restlessness, you would describe it as "anxious"
or "restless."
Sad, irritable, angry, despair: If the patient's mood is characterized by a
general feeling of sadness, irritability, anger, or despair, you would describe
it as "sad," "irritable," "angry," or "despaired."
Shallow, blunted, indifferent, restricted, inappropriate: If the patient's mood is
characterized by a shallow, blunted, indifferent, restricted, or inappropriate
emotional expression, you would describe it as such.
Labile: If the patient's mood is characterized by frequent or rapid shifts in
emotional expression, you would describe it as "labile."
Anhedonia: If the patient experiences a reduced ability to experience
pleasure or enjoyment, you would describe it as "anhedonia."
Mental State Examination

Subjective and Objective Measures:
Subjective: Asking the patient directly, "how do you feel?" can provide
valuable information about the patient's self-reported mood state.
Objective: Observing the patient's nonverbal behavior, such as facial
expressions, body posture, and tone of voice, can also provide important
clues about the patient's mood state.
Stability, Reactivity, and Persistence of Mood:
Stability: If the patient's mood remains relatively consistent over time, you
would describe it as "stable."
Reactivity: If the patient's mood is easily influenced by environmental or
interpersonal factors, you would describe it as "reactive."
Persistence: If the patient's mood persists over a period of time, you would
describe it as "persistent."
It's important to note that mood assessment is a complex process that requires
careful observation, active listening, and empathy. As with all aspects of the
MSE, it's essential to maintain a non-judgmental, supportive, and empathic
approach to the patient.
Affect
Assessing affect during an MSE involves evaluating the quality, range, depth,
and appropriateness of the patient's emotional expression. Here are some
guidelines for assessing specific aspects of affect:
Quality of Affect:
Flat or blunted: If the patient's affect is flat or blunted, meaning there is little
or no emotional expression, you would describe it as such.
Restricted or constricted: If the patient's affect is restricted or constricted,
meaning emotional expression is limited in range or intensity, you would
describe it as such.
Labile or unstable: If the patient's affect is labile or unstable, meaning
emotional expression is variable and rapidly changing, you would describe it
as such.
Appropriate: If the patient's affect is appropriate, meaning emotional
expression is consistent with the content of the patient's thoughts or the
environment, you would describe it as such.
Inappropriate: If the patient's affect is inappropriate, meaning emotional
expression is not consistent with the content of the patient's thoughts or the
environment, you would describe it as such.
Mental State Examination

Congruent: If the patient's affect is congruent, meaning emotional
expression is consistent with the content of the patient's thoughts or the
environment, you would describe it as such.
Range of Affect:
Broad: If the patient's affect is broad, meaning there is a wide range of
emotional expression, you would describe it as such.
Restricted or narrow: If the patient's affect is restricted or narrow, meaning
emotional expression is limited in range, you would describe it as such.
Depth or Intensity of Affect:
Normal: If the patient's affect has a normal depth or intensity, meaning
emotional expression is appropriate for the situation and environment, you
would describe it as such.
Increased: If the patient's affect has an increased depth or intensity,
meaning emotional expression is exaggerated or extreme for the situation
and environment, you would describe it as such.
Blunted: If the patient's affect has a blunted depth or intensity, meaning
emotional expression is reduced or absent for the situation and
environment, you would describe it as such.
Appropriateness of Affect:
Appropriate: If the patient's affect is appropriate, meaning emotional
expression is consistent with the content of the patient's thoughts or the
environment, you would describe it as such.
Inappropriate: If the patient's affect is inappropriate, meaning emotional
expression is not consistent with the content of the patient's thoughts or the
environment, you would describe it as such.
It's important to note that affect assessment is a complex process that requires
careful observation, active listening, and empathy. As with all aspects of the
MSE, it's essential to maintain a non-judgmental, supportive, and empathic
approach to the patient.
Thought
Stream and form of thought
To assess the stream and form of thought on MSE, the mental health
professional may observe the patient's speech and ask questions designed to
elicit information about the patient's thoughts and perceptions. The following are
some key areas to assess:
Mental State Examination
11
1. Spontaneity: The ease with which a person generates ideas and responses.
Is the patient able to answer questions without difficulty or do they struggle
to come up with answers?
2. Productivity: The amount of speech and ideas generated by the patient. Is
the patient talkative or quiet? Do they seem to have a lot to say or do they
struggle to come up with ideas?
3. Flight of ideas: Rapid shifts in topic that may be difficult to follow. Does the
patient jump from topic to topic without clear connections between them?
4. Prolixity: Excessive talkativeness or wordiness. Does the patient ramble on
without getting to the point?
5. Poverty of content: Lack of substantive ideas or content. Does the patient
provide vague or superficial responses to questions?
6. Thought block: A sudden interruption in the flow of thought. Does the patient
stop talking abruptly or struggle to find words?
7. Continuity of thought: The coherence and connectedness of a person's
ideas. Do the patient's ideas flow logically from one to another?
8. Loosening of association: The lack of logical connection between ideas. Do
the patient's ideas seem disjointed or unrelated to one another?
9. Tangentiality: A tendency to move away from the topic at hand. Does the
patient answer questions tangentially rather than directly?
10. Circumstantiality: Excessive and unnecessary detail provided in a response.
Does the patient get bogged down in irrelevant details?
11. Illogical thinking: Lack of logical coherence or reasoning. Do the patient's
ideas seem irrational or illogical?
12. Perseveration: Repetition of the same idea or response. Does the patient
repeat the same response to different questions?
13. Verbigeration: Repetitive and meaningless speech. Does the patient use
nonsensical words or phrases repeatedly?
Assessing the stream and form of thought can provide valuable insights into a
person's mental state and functioning. Mental health professionals use the
information gathered during the MSE to diagnose mental health conditions,
develop treatment plans, and monitor progress over time.
Content of thought
Assessing the content of thought is an important component of the Mental
Status Examination (MSE) used by mental health professionals to evaluate a
Mental State Examination
12
person's mental state and functioning. The following are some key areas to
assess when evaluating the content of thought:
1. Preoccupations: Persistent, intrusive thoughts that a person cannot dismiss
or control. Does the patient seem preoccupied with a particular thought or
idea?
2. Obsessions: Intrusive thoughts or impulses that cause significant anxiety or
distress. Does the patient have obsessions that interfere with their daily
functioning?
3. Phobias: Intense, irrational fears of specific objects or situations. Does the
patient have a phobia that interferes with their daily functioning?
4. Delusions: Fixed, false beliefs that are not shared by others in the same
culture or community. The following are different types of delusions that may
be assessed:
Persecution: Belief that one is being targeted or persecuted by others.
Reference: Belief that random events or objects have a special significance
or meaning specifically for oneself.
Grandeur: Belief that one is exceptionally powerful, important, or talented.
Love: Belief that someone is in love with oneself.
Jealousy: Belief that one's partner or spouse is unfaithful.
Guilt: Belief that one is responsible for something terrible or that they have
committed a terrible crime.
Nihilism: Belief that life is meaningless or that the world or oneself does not
exist.
Poverty: Belief that one is impoverished or destitute, even when evidence
suggests otherwise.
Somatic symptom: Belief that one has a physical illness or defect, even
when evidence suggests otherwise.
Hopelessness: Belief that there is no hope for the future.
Helplessness: Belief that one is powerless and unable to control their
circumstances.
Worthlessness: Belief that one is worthless and undeserving of love or
respect.
Suicidal ideation: Thoughts of suicide or self-harm.
Control: Belief that one's thoughts, feelings, or actions are being controlled
by an outside force.
Mental State Examination
13
Thought insertion: Belief that someone or something is inserting thoughts
into one's mind.
Thought withdrawal: Belief that someone or something is removing thoughts
from one's mind.
Thought broadcasting: Belief that one's thoughts can be heard by others.
1. Neologisms: Invented words or phrases that have no meaning to others.
Does the patient use words or phrases that are not understood by others or
that have no commonly accepted meaning?
Assessing the content of thought can provide valuable insights into a person's
mental state and functioning. Mental health professionals use the information
gathered during the MSE to diagnose mental health conditions, develop
treatment plans, and monitor progress over time.
Perception
Assessing perception is an important part of the Mental State Examination (MSE) in
clinical practice. The following are some guidelines on how to assess different
aspects of perception:
1. Hallucination: Ask the patient if they are experiencing any unusual sensory
experiences, such as seeing or hearing things that others do not. You can also
ask about the frequency, duration, and content of the hallucinations.
2. Illusions and misinterpretations: Ask the patient if they have had any
experiences where they misinterpreted sensory information, or if they have
experienced any sensory distortions.
3. Depersonalisation/derealisation: Ask the patient if they feel detached from their
own body or surroundings. You can also ask about the frequency, duration, and
triggers for these experiences.
4. Somatic passivity phenomenon: Ask the patient if they feel that their actions or
movements are being controlled by an external force or if their body feels
unfamiliar to them.
5. Autoscopy: Ask the patient if they have ever felt like they are seeing their own
body from a distance.
6. Abnormal vestibular sensations: Ask the patient if they have experienced any
unusual sensations related to balance or orientation, such as feeling like the
room is spinning.
7. Sense of presence: Ask the patient if they have ever felt like there is a presence
in the room with them, even if they cannot see or hear anything.
Mental State Examination

It is important to note that some of these experiences may be indicative of
underlying psychiatric or neurological conditions, so it is important to follow up with
further assessments or referrals as necessary.
Cognition Assessment
Consciousness
Assessing consciousness involves evaluating a person's level of alertness and
awareness of their surroundings. The intensity of stimulation needed to arouse a
patient can provide useful information about their level of consciousness.
However, it is important to use a standardized approach to assess
consciousness, such as the Glasgow Coma Scale (GCS), to ensure accuracy
and consistency in the assessment.
The GCS is a commonly used tool for assessing consciousness and consists of
three components: eye opening, verbal response, and motor response. Each
component is assigned a score, and the scores are added together to give a
total score that ranges from 3 (deep coma) to 15 (fully conscious).
The Glasgow Coma Scale (GCS) is a standardized tool that is commonly
used to assess the level of consciousness in patients. The GCS assesses
three aspects of neurological function: eye-opening, verbal response, and
motor response. The scores for each aspect are then added together to give
a total score between 3 and 15.
To assess consciousness using the GCS, you should follow these steps:
1. Eye-Opening: Observe the patient's eye opening. Score 4 if the patient
opens their eyes spontaneously, 3 if the patient opens their eyes to
verbal stimuli, 2 if the patient opens their eyes to painful stimuli, and 1 if
the patient's eyes remain closed even to painful stimuli.
2. Verbal Response: Assess the patient's verbal response. Score 5 if the
patient is alert and oriented, 4 if the patient is confused but can answer
questions, 3 if the patient can speak but their responses are
inappropriate, 2 if the patient makes incomprehensible sounds, and 1 if
the patient does not make any sounds.
3. Motor Response: Test the patient's motor response. Score 6 if the
patient follows commands, 5 if the patient localizes to painful stimuli, 4 if
the patient withdraws from painful stimuli, 3 if the patient flexes their
arms in response to painful stimuli, 2 if the patient extends their arms in
response to painful stimuli, and 1 if there is no motor response to painful
stimuli.
After assessing each aspect, add the scores together to obtain the total
score, which ranges from 3 to 15. A score of 15 indicates that the patient is
Mental State Examination
15
fully conscious, while a score of 3 indicates a deep coma.
In summary, the GCS is a standardized tool used to assess the level of
consciousness in patients. It evaluates three aspects of neurological
function, including eye-opening, verbal response, and motor response. The
scores for each aspect are then added together to give a total score between
3 and 15, with a higher score indicating a higher level of consciousness.
In addition to the GCS, the Modified Rankin Scale (MRS) and the National
Institutes of Health Stroke Scale (NIHSS) are other tools that can be used to
assess consciousness.
The Glasgow Coma Scale (GCS) is a neurological scale used to assess the
level of consciousness in a patient following a head injury or other
neurological events such as stroke. The GCS assesses the patient's best
response in three areas: eye-opening, verbal response, and motor response.
The scores for these areas range from 1 to 6, with a maximum possible
score of 15. A score of 15 indicates that the patient is fully conscious, while a
score of 3 or less indicates a deep coma. The GCS is widely used in the
clinical setting as a tool for triage, monitoring, and prognostication in patients
with altered level of consciousness.
The Modified Rankin Scale (MRS) is a scale used to assess the functional
status of patients who have suffered a stroke or other neurological events.
The scale ranges from 0 to 5, with higher scores indicating worse functional
status. The MRS evaluates six categories of disability: 0 represents no
symptoms, 1 represents no significant disability, 2 represents slight disability,
3 represents moderate disability, 4 represents moderately severe disability,
and 5 represents severe disability. The MRS is often used to evaluate the
functional outcome of patients following a stroke and helps to guide
rehabilitation and discharge planning.
The National Institutes of Health Stroke Scale (NIHSS) is a neurological
scale used to evaluate the severity of neurological deficits in patients with
acute stroke. The scale is composed of 15 items that evaluate different
aspects of neurological function such as level of consciousness, language
function, motor function, and sensory function. Each item is scored based on
the severity of the deficit, with a maximum score of 42. The NIHSS is widely
used in clinical practice and clinical trials to assess the severity of
neurological deficits in patients with acute stroke and to guide treatment
decisions.
In summary, the GCS, MRS, and NIHSS are three commonly used scales in
the clinical setting to evaluate different aspects of neurological function.
These scales are useful tools for triage, monitoring, and prognostication in
patients with altered level of consciousness, functional impairment following
Mental State Examination
16
a stroke, and acute stroke severity. By using these scales, healthcare
professionals can accurately evaluate the neurological function of patients
and guide clinical decision-making to optimize patient outcomes.
When assessing consciousness, it is important to also evaluate for other factors
that may affect a person's level of alertness, such as medications, metabolic
abnormalities, and neurological conditions. The presence of confusion,
somnolence, clouding, delirium, stupor, or coma can also provide additional
information about the person's level of consciousness and overall neurological
function.
Overall, a comprehensive mental status examination (MSE) is necessary to fully
evaluate a person's level of consciousness, and healthcare professionals should
use standardized tools and protocols to ensure accuracy and consistency in
their assessments.
Orientation
Orientation is a key component of the mental status examination (MSE) and
refers to the patient's awareness of their surroundings and situation. To assess
orientation, you should ask the patient a series of questions related to time,
place, and person.
1. Time: Start by asking the patient about the current time, day, date, month,
year, and how long they have been in the hospital. For example, you could
ask "What is today's date?" or "Can you tell me the time right now?"
2. Place: Next, ask the patient about their current location, building, city, and
country. For example, you could ask "Where are you right now?" or "What
city are you in?"
3. Person: Finally, ask the patient about their own name and identity, as well as
the identities of the people around them and their roles. For example, you
could ask "Can you tell me your name?" or "Do you know who I am and
what my role is?"
Asking these questions will allow you to assess the patient's level of orientation
and awareness. A fully oriented patient should be able to answer all questions
correctly, while a patient with impaired orientation may struggle with one or more
of the questions.
It is also important to note that orientation can vary depending on factors such
as age, culture, and level of education. Therefore, it is important to take these
factors into account when assessing a patient's level of orientation.
Attention
Assessing attention is an important part of the mental status examination (MSE),
as it can provide valuable information about a patient's cognitive function. To
Mental State Examination
17
assess attention, one common method is the digit span test. Here are the steps
to administer this test:
1. Explain the test to the patient: Explain to the patient that you will be saying a
series of numbers and that their task is to repeat them back to you in the
same order (forwards) or reverse order (backwards).
2. Begin the test: Start with a sequence of two digits, such as "3-7", and ask
the patient to repeat them back to you. If the patient repeats the digits
correctly, move on to the next sequence of three digits, such as "2-8-4".
Continue to increase the number of digits in each sequence until the patient
makes three consecutive errors or reaches the maximum length of the test
(often eight digits).
3. Score the test: Score the test by counting the number of digits in the longest
sequence that the patient can repeat correctly in either forwards or
backwards order.
4. Interpret the results: Patients who are able to repeat longer sequences of
digits correctly are generally considered to have better attention skills.
Patients who struggle with shorter sequences may have difficulty with basic
attention skills.
In summary, to assess attention using the digit span test, start with a sequence
of two digits and gradually increase the length of the sequence until the patient
makes three consecutive errors or reaches the maximum length of the test.
Count the number of digits in the longest sequence that the patient can repeat
correctly in either forwards or backwards order, and use this as an indicator of
their attention skills.
Concentration
Assessing concentration is an important part of the mental status examination
(MSE), as it can provide valuable information about a patient's ability to sustain
focus and attention. One common method to assess concentration is the serial
subtraction test, which involves asking the patient to subtract a specific number
from a given starting point. Here are the steps to administer this test:
1. Explain the test to the patient: Explain to the patient that you will be asking
them to perform a simple math task involving subtraction.
2. Choose the starting point and subtraction number: Choose a starting point
and subtraction number that is appropriate for the patient's age and
cognitive abilities. For example, you could ask the patient to subtract serial 7
from 100, or serial 3 from 50, or count backwards from 20.
3. Start the test: Ask the patient to begin subtracting the given number from the
starting point, and keep track of their answers and the time it takes them to
Mental State Examination
18
perform the test. For example, if you chose to use serial 7 from 100, the
patient should say "93, 86, 79, 72" and so on until they reach the end of the
test or are unable to continue.
4. Interpret the results: Patients who are able to perform the test quickly and
accurately are generally considered to have good concentration skills.
Patients who make errors or take longer to complete the test may have
difficulty with sustaining focus and attention.
In summary, to assess concentration using the serial subtraction test, choose an
appropriate starting point and subtraction number, ask the patient to perform the
test, and keep track of their answers and the time it takes them to complete the
test. Use this information to evaluate their concentration skills and identify any
potential issues with focus and attention.
Memory
Assessing memory is an important part of the mental status examination (MSE),
as it can provide valuable information about a patient's ability to retain and recall
information. Here are the steps to assess memory:
1. Immediate retention and recall: This can be assessed during the digit span
test, as mentioned in the previous answers. The examiner can give a series
of digits and ask the patient to repeat them back in the same or reverse
order. The ability to recall this information immediately can give an indication
of the patient's immediate retention and recall abilities.
2. Recent memory: This can be assessed by asking the patient to recall recent
events or information, such as what they had for meals or what they did
earlier in the day. Alternatively, the examiner can give a specific item to be
memorized, such as a name or a word, and ask the patient to recall it after a
short period of time, usually around 15 minutes.
3. Remote memory: This can be assessed by asking the patient to recall
information from the past, such as the date and place of their marriage or
the names and birthdays of their children. This can give an indication of the
patient's long-term memory abilities.
4. Note for any amnesia: It is important to note any amnesia, whether it is
anterograde (inability to form new memories) or retrograde (inability to recall
past memories). Patients with amnesia may have difficulty with memory
tasks and may require further evaluation.
5. Note for any confabulation: Confabulation is a memory disorder in which
patients fabricate or distort memories without the intention to deceive. It is
important to note any instances of confabulation during the memory
Mental State Examination
19
assessment, as it can provide valuable information about the patient's
memory function and potential underlying neurological issues.
In summary, to assess memory during the MSE, the examiner can use the digit
span test to assess immediate retention and recall, ask the patient to recall
recent events or information, test their ability to recall information from the past,
and note any instances of amnesia or confabulation.
Intelligence
Assessing intelligence is a complex and multi-faceted process, and there are
many different approaches that can be used. Here are a few methods that could
be used to assess intelligence:
1. Standardized intelligence tests: One common way to assess intelligence is
through the use of standardized intelligence tests, such as the Wechsler
Adult Intelligence Scale (WAIS) or the Stanford-Binet Intelligence Scale.
These tests are designed to measure a wide range of cognitive abilities,
including verbal and nonverbal reasoning, working memory, processing
speed, and more.
2. Observation and problem-solving tasks: Another way to assess intelligence
is to observe how individuals approach and solve problems in real-world
situations. This could involve tasks such as solving puzzles or completing a
complex project.
3. Questionnaires and interviews: Questionnaires and interviews can be used
to assess a person's general knowledge, problem-solving skills, and ability
to think critically. These assessments may also explore personality traits,
such as creativity, perseverance, and curiosity, which can be important
indicators of intelligence.
4. Reading, writing, and math assessments: Reading, writing, and math skills
are often considered key components of intelligence. Assessments of these
skills can include tests of reading comprehension, writing ability, and basic
math skills, such as addition, subtraction, multiplication, and division.
5. Multidimensional assessment: Assessing intelligence in a multidimensional
way is the best way to ensure a comprehensive understanding of a person's
intellectual abilities. Therefore, using multiple assessment methods and
tools, as well as considering multiple aspects of intelligence, can provide a
more accurate picture of a person's intellectual strengths and weaknesses.
It is important to note that no single assessment or test can provide a complete
picture of a person's intelligence. Intelligence is a complex and multifaceted
construct, and assessing it requires a comprehensive approach that considers a
variety of factors and methods.

Abstract thinking
Assessing abstract thinking involves evaluating an individual's ability to
understand complex concepts and think in non-literal or symbolic ways. Here
are some methods that can be used to assess abstract thinking:
1. Proverb testing: This involves asking the patient to interpret the meaning of
a proverb, such as the examples you provided. The patient's ability to
understand and interpret the proverb in a non-literal way can provide
insights into their abstract thinking abilities.
2. Similarities and differences: This method involves presenting pairs of
familiar objects and asking the patient to identify the similarities and
differences between them. The patient's ability to identify abstract
similarities and differences beyond the literal characteristics of the objects
can provide insights into their abstract thinking abilities.
3. Analogy testing: This method involves asking the patient to complete
analogies, such as "hot is to cold as up is to ____." The patient's ability to
understand the abstract relationship between the two concepts can provide
insights into their abstract thinking abilities.
4. Visual-spatial tests: These tests involve presenting the patient with complex
visual-spatial problems and asking them to solve them. The patient's ability
to understand and manipulate abstract visual-spatial concepts can provide
insights into their abstract thinking abilities.
When assessing abstract thinking, it is important to evaluate the
appropriateness of the patient's answers, as well as their level of concreteness
or abstractness. It is also important to consider cultural and linguistic factors that
may affect the patient's ability to understand and interpret the tasks presented.
Insight
Assessing a patient's insight can be an essential aspect of a mental status
examination (MSE). Here are the steps you can follow to assess the patient's
insight on their illness:
1. Start by asking the patient about their present state and whether they
believe they have an illness.
2. If they acknowledge their illness, inquire about the type of illness they
perceive themselves to have, whether it's physical, psychological, or both.
3. Ask if they feel that treatment is necessary for their condition.
4. Inquire about their hope for recovery and whether they believe that they will
recover from their illness.
5. Ask about their perceived cause of the illness.
Mental State Examination
21
6. Based on the patient's response to the above questions, you can grade their
insight on a six-point scale. The grading is as follows:
Complete denial of illness
Slight awareness of being sick and needing help, but denying it at the same
time
Awareness of being sick, but attributed to external or physical factors
Awareness of being sick, due to something unknown in self
Intellectual insight
True emotional insight
It's important to note that insight is subjective and can vary from person to
person. Therefore, it's crucial to listen to the patient's responses without bias
and to follow up on their answers with further questioning if necessary.
Judgement
Assessing a patient's judgment can also be a vital aspect of a mental status
examination (MSE). Here are the steps you can follow to assess a patient's
judgment:
1. Start by observing the patient's behavior and social interactions during their
hospital stay and during the interview session. Evaluate their ability to make
appropriate decisions based on their situation, such as following hospital
rules, adhering to treatment plans, and interacting with staff and other
patients in a socially appropriate manner. This will provide insights into their
"personal judgment."
2. Ask the patient hypothetical questions about how they would handle certain
situations, such as being lost in an unfamiliar place or encountering a
dangerous animal. Their responses will help assess their "test judgment."
3. Based on your observations and their responses, rate their judgment as
Good/Intact/Normal or Poor/Impaired/Abnormal.
It's important to note that judgment is also subjective and can vary depending on
the patient's background, experiences, and current mental state. Therefore, it's
crucial to listen to the patient's responses without bias and to follow up on their
answers with further questioning if necessary. Also, it's important to take into
consideration any relevant medical or psychiatric history that may affect their
judgment.
