The Mental Status Examination
This is the primary type of examination used in psychiatry. Though psychiatrists
do not use many of the more intrusive physical examination techniques (such
palpation, auscultation, etc.), psychiatrists are expected to be expert observers,
both of significant positive and negative findings on examinations. This
observation should take place throughout the patient encounter; it is not limited
to any one point. However, the observations are then recorded into a specific
structured format that is labeled the Mental Status Examination (MSE). When
properly done, the MSE should give a detailed "snapshot" of the patient as he
presented during the interview.
Often beginners become confused about the difference between this and
other parts of the history. A simple way to keep it apart is to remember that this
is, as the title says, an examination, therefore it should be limited to what is
observed. The rest should go in the history. As an example, if a patient reports
that they have been hearing voices throughout the day, but deny hearing them
during the interview and do not seem to be responding to internal stimuli, one
would not report the hallucinations as part of the MSE, but rather include it
earlier in the history. Conversely, if the patient denies any history of
hallucination, but seems to be responding to internal stimuli throughout the
examination, one would report the phenomenon on the MSE.
The MSE can be divided into the following major categories: (1) General
Appearance, (2) Emotions, (3) Thoughts, (4) Cognition, (5) Judgment and Insight.
These are described in more detail in the following sections.

The Mental Status Examination

This is the primary type of examination used in psychiatry. Though psychiatrists do not use many of the more intrusive physical examination techniques (such palpation, auscultation, etc.), psychiatrists are expected to be expert observers, both of significant positive and negative findings on examinations. This observation should take place throughout the patient encounter; it is not limited to any one point. However, the observations are then recorded into a specific structured format that is labeled the Mental Status Examination (MSE). When properly done, the MSE should give a detailed "snapshot" of the patient as he presented during the interview. Often beginners become confused about the difference between this and other parts of the history. A simple way to keep it apart is to remember that this is, as the title says, an examination , therefore it should be limited to what is observed. The rest should go in the history. As an example, if a patient reports that they have been hearing voices throughout the day, but deny hearing them during the interview and do not seem to be responding to internal stimuli, one would not report the hallucinations as part of the MSE, but rather include it earlier in the history. Conversely, if the patient denies any history of hallucination, but seems to be responding to internal stimuli throughout the examination, one would report the phenomenon on the MSE. The MSE can be divided into the following major categories: (1) General Appearance, (2) Emotions, (3) Thoughts, (4) Cognition, (5) Judgment and Insight. These are described in more detail in the following sections.

General Description

As implied, this is a general description of the patient’s appearance. Being detailed and accurate is important, and such observations can be of great use to the next examiner. Imagine, for example, if a patient presents looking disheveled, poorly groomed with poor hygiene to an emergency department, but a note from only a month ago reports the same patient to have been well dressed and groomed. Something is going on! Some of the areas that might be commented on, particularly if they have significant negative or positive findings include:

Appearance

One should describe the prominent physical features of an individual. At least one writer on the subject has suggested this should be detailed enough "such that a portrait of the person could be painted that highlights his or her unique

aspects” but that is probably asking a lot. Some aspects of appearance once might note include a description of a patient’s facial features, general grooming, hair color texture or styling, and grooming, skin texture, scar formation, tattoos, body shape, height and weight, cleanliness and neatness, posture and bearing, clothing (type, appropriateness) or jewelry.

Motor Behavior

The examination should incorporate any observation of movement or behavior. Some aspects of motor behavior that might be commented on include gait, freedom of movement, firmness and strength of handshake, any involuntary or abnormal movements, tremors, tics, mannerisms, lip smacking or akathisias

Speech

This in not an evaluation of language or thought (save that for later), but a behavioral/mechanical evaluation of speech. Items that might be commented on include the rate of speech, the spontaneity of verbalizations, the range of voice intonation patterns, the volume of speech, and any defects with verbalizations (stammering or stuttering).

Attitudes

One should comment on how the patient related to the examiner. This usually includes a discussion of the patient’s degree of cooperativeness with the examiner. When appropriate, a recording of the evaluator’s attitude toward the patient might be appropriate, as we believe such reactions (“countertransference”) may be useful information. Such discussions should be done with the understanding that the patient has a legal right to read the record, and any strong emotions or reactions should be recorded in a diplomatic manner. Emotions For the sake of consistency, the observation of a patient’s emotions is divided into a discussion of mood and affect. Mood is usually defined as the sustained feeling tone that prevails over time for a patient. At times, the patient will be able to describe their mood. Otherwise, evaluator must inquire about a patient’s mood, or infer it from the rest of the interview. Qualities of mood that may be commented on include the depth of the mood, the length of time that it prevails, and the degree of fluctuation. Common words used to describe a mood include the following: Anxious, panicky, terrified, sad, depressed, angry, enraged, euphoric, and guilty.

said; and Loose associations : a jumping from one topic to another with no apparent connection between the topics. In the other direction, a perseveration refers the patient's repeating the same response to a variety of questions and topics, with an inability to change his or her responses or to change the topic. Other less common abnormalities of thought process include the following: Neologisms: words that patients make up and are often a condensation of several words that are unintelligible to another person. Word salad: incomprehensible mixing of meaningless words and phrases. Clang associations: the connections between thoughts become tenuous, and the patient uses rhyming and punning. Disturbances of thought content include such abnormalities as Perceptual Disturbances and Delusions. The most common perceptual disturbances are Hallucinations , which are perceptual experiences that have no external stimuli. Hallucinations can be auditory (i.e., hearing noises or voices that nobody else hears); visual (i.e., seeing objects that are not present); tactile (i.e., feeling sensations when there is no stimulus for them); gustatory (i.e., tasting sensations when there is no stimulus for them); or olfactory (i.e., smelling odors that are not present). They are not necessarily pathonogmonic of any specific disorder. For example hypnagogic (i.e., the drowsy state preceding sleep) and hypnopompic (i.e., the semiconscious state preceding awakening) hallucinations are experiences associated with normal sleep and with narcolepsy. Another disorder of perception is an Illusion , which is a false impression that results from a real stimulus. Other examples of abnormal perceptions include Depersonalization, which is a patients' feelings that he is not himself, that he is strange, or that there is something different about himself that he cannot account for, and Derealization, which expresses a patients' feeling that the environment is somehow different or strange but she cannot account for these changes. Delusions can be defined as false fixed beliefs that have no rational basis in reality, being deemed unacceptable by the patient's culture. Primary delusions are unrelated to other disorders. Examples include thought insertion, thought broadcasting, and beliefs about world destruction. Secondary delusions are based on other psychological experiences. These include delusions derived from hallucinations, other delusions, and morbid affective states. Types of delusions include those of persecution, of jealousy, of guilt, of love, of poverty, and of nihilism. The most common are persecutory delusions , in which one believes, erroneously, that another person or group of persons it trying to do harm to oneself. Note that this is often referred to as a paranoid delusion, but that is a misuse of the word paranoid , which is a more generic in meaning and does not imply a specific type of delusion. Other abnormal thoughts sometimes found as part of a delusion include ideas of reference and ideas of influence. Ideas of reference are erroneous beliefs that an unrelated event in fact pertains to an individual. Thus, if a patient observes a car on a

street make a sudden turn, and assumes that it is because the driver is following the patient, that would be an idea of reference. Such ideas can become even more improbable, such as a belief that something an announcer is saying on the television is actually a coded message intended for the patient. Ideas of influence are similar in that the patient may believe that somehow they caused an unrelated event to happen (for example, believing that through one’s will one was able to cause an accident, even though one was not directly involved in any way). In addition to describing the type of delusion a patient has, one wants to comment on other aspects of the delusion, such as the quality of the delusion, or the degrees of organization of the delusion. There are other types of abnormal thoughts. Examples include obsessions and compulsions, which, though irrational, are not as severe a disorder as hallucinations or delusions. Obsessions are repetitive, unwelcome, irrational thoughts that impose themselves on the patient's consciousness over which he or she has no apparent control. They are accompanied by feelings of anxious dread and are thought to be ego alien (coming from “outside” one’s normal self or desires), unacceptable, and undesirable. They are often resisted by the patient. Compulsions are repetitive stereotyped behaviors that the patient feels impelled to perform ritualistically, even though he or she recognizes the irrationality and absurdity of the behaviors. Although no pleasure is derived from performing the act, there is a temporary sense of relief of tension when it is completed. These are usually associated with obsessions. Some other specific thoughts to ask about, which may be of great practical concern, suicidal and homicidal. These should be inquired about on any examination, as patients with such thoughts commonly present to medical settings, but often do not spontaneously reveal these thoughts.

Attention and Concentration. Attention refers to the ability to focus and direct one’s cognitive in a physiologically aroused state. Concentration refers to the ability to maintain attention for a period. They need not go together: one can imagine a person who is attentive, but cannot concentrate on any one thing: for example a patient with early Alzheimer’s disease who is easily distracted. The patient’s attention and concentration during the interview should be noted. Most screening tests for dementia include a test of these items. For example, on the Folstein Mini-Mental Status Examination (below), a patient is asked to do serial seven’s (described below). Though this does involve some mathematical skill (about a 3rd^ grade level), the ability to sustain the task over time implies a reasonable degree of attention and concentration. An example of a specific attentional task is the digit span, in which a patient is asked to repeat increasing lengths of numbers forwards, and then backwards. A normal person should be able to recite about 7 numbers forwards. A person usually can recite a reverse series that is 2 less than their forward series (thus, 5 for most people). It is important to recite the numbers in a relatively monotone way, put an equal interval between the numbers to avoid potential cues. A simple test of concentration is to ask a person to count backwards starting at 65 and stopping at 49. The instructions should be given only once, with no cuing during the task. Another example is the serial sevens task, in when a patient is asked to start at 100 and subtract 7, then keep subtracting 7 from each answer. Usually a person is asked to perform 5 subtractions, and each correct interval of 7 scores 1 point. Memory. Though variously defined, for the purposes here, memory will refer to the process of learning involving the registering of information, the storage of that information, and the ability to retrieve the information later. Thus, there are separate component of memory, and the boundaries between them are somewhat controversial. A simple approach to testing will be used here, and memory will be divided into registration , short-term memory , and long-term memory. Registration refers to the ability to repeat information immediately. It is usually limited in capacity to about seven bits of information. Registration is usually tested by asking a patient to repeat a series of items (for example, three unrelated words). If the patient cannot do on the first try, the words should be repeated until the patient can do it, and the number of tries should be recorded (more than 2 trials for 3 words would be abnormal). Registration should always be ascertained before testing other parts of memory: an inattentive patient who cannot register properly may appear to have a deficit of short or long-term memory, when in fact the memory items were never incorporated properly for information storage. Short-term memory refers to the storage of information beyond the immediate (registration) period, but prior to the consolidation of memory into

long-term memory. Practically speaking, it lasts from a few seconds to a few minutes, and may or may not be temporary (depending on the purpose of the memory). It is limited in capacity, though the specific limits are very individual. Short-term memory can be tested by asking a patient to recall 3 or 4 words after a five-minute delay. After the initial test, a patient can be cued, or given multiple changes, which subsequent performance being recorded (although if the patient were being scored, these correct answers would not add to the score). Other typical tests of short-term memory include reading a paragraph to a patient and asking them to recall as much information from the story as possible in 5 minutes. Long-term memory is usually divided into procedural and declarative memory. Procedural memory refers to the ability to remember a specific set of skills. As one thinks of any task one has learned–say, driving a car–it is clear that there is a point at which one no longer has to think about the specific steps in the task—it has become unconscious and automatic. Procedural memory is generally not assessed during a standard mental status examination, but can be specifically tested when indicated. For example, a person may be asked to act out a specific task (“show me how you brush your teeth”). Declarative memory refers to the retention of data or facts, which can be verbal or nonverbal (i.e., sounds, images). In contrast to short-term memory, it is not temporary (though it can decay over time), and it has no known limit. Long-term (declarative) memory is usually tested by asking a patient to recall past details. These details may be personal (wedding dates, graduations, past medical history–all of which would have to then be independently confirmed), or historical (important historical dates that a patient would reasonably be expected to know, based on their own upbringing and culture). Typically, a patient is asked to name past presidents, but some patients (ex. recent immigrants) may now know politics. One can usually assess appropriate questions after learning of a patient’s background. Some events are fairly universal: Pearl Harbor, for example, at least for people living in the US who are old enough to have been old enough in 1941. Similarly, one can expect, at least in this general area, that asking when the Red Sox won the World Series will be pretty reliable, at least for a while. Constructional Ability refers to the ability to recognize the relationship of different objects in the world. Though occasionally neglected during cognitive testing, it is of great practical significance, particularly if a person wishes to drive, or live alone. Constructional tasks require reasonable vision, motor coordination, strength, praxis and tactile sensation, and in cases in which patient’s appear to have a deficit in this ability, these other domains should be tested as well. Usually, constructional ability is tested by having a person copy a design, such as a transparent cube, or a clock. The Folstein Mini Mental Status examination includes a constructional task in which a person is asked to draw

Reliability Upon completion of an interview, the psychiatrist assesses the reliability of the information that has been obtained. Factors affecting reliability include the patient's intellectual endowment, his or her (perceived) honesty and motivations, the presence of psychosis or organic defects and the patient's tendency to magnify or understate his or her problems. In cases in which there is a strong reason to question a patient’s reliability (ex. significant dementia), the assessment of reliability should be discussed early in the examination, rather than waiting to the end to reveal that much of the information reported already is unreliable!
