MENTAL STATUS EXAMINATION
Outline Operational definition Purposes Components Behavior Cognition Emotion Cognitive examination Mini Mental Status
MENTAL STATUS EXAMINATION: What is it? ASSESSMENT of the: Behavior (see it all) Emotion (see some of it) Cognition (see none of it) Exhibited by the patient during the entire medical encounter
PURPOSES Abnormalities/deficits in: • Detect • Describe • Neuroanatomical localization • Assess functional implications of Abnormalities/deficits in: • Behavior • Emotion • Cognition
ABNORMALITIES & DEFICITS Require diagnostic explanation May compromise capacity to coherently and reliably describe medical state to give informed consent to adhere to a therapeutic plan
MEDICAL ENCOUNTER Comprehensive global assessment

REASONING LANGUAGE COGNITIVE EXAM (“Mental status”) MEMORY ATTENTION AROUSAL
REASONING Must know LANGUAGE education Can the patient hear? COGNITIVE EXAM (“Mental status”) Must know education REASONING LANGUAGE MEMORY ATTENTION AROUSAL Can the patient hear?
MEMORY Immediate memory = attention Recent memory (episodic) Recall of three words at 5 minutes Ensure that pt has registered the items “Repeat these words after me, I want you to remember them.” Remote memory (semantic & episodic) Tends to overlap with knowledge, most of what we ask is overlearned Presidents, date of W.W.II, etc..
REASONING (Higher cognitive fx) Tests problem solving, abstract thinking Fund of knowledge - overlaps with remote memory How many weeks in a year? Name four presidents since 1940? What causes rust? Calculations Add, subtract, multiple, divide Sequences 1, 2, 3, ... 1, 4, 9, 16, .... 2, 3, 5, 7, 11, ...
REASONING (continued) Similarities Apple - orange Car - airplane Poem - novel Proverbs Don’t cry over spilt milk A stitch in time saves nine People who live in glass houses shouldn’t throw stones
BEHAVIOR Appearance Attitude Activity Speech Dress Grooming Hygiene COGNITION Thought content Thought progression Insight/judgment Arousal Attention Memory Language Reasoning EMOTION Affect Mood Suicide Homicide
EMOTION AFFECT “Affect is to weather as mood is to climate” • predominate sad, euphoric, angry, anxious • intensity unmodulated • range narrow, broad • congruence incongruent with content MOOD euthymic, dysthymic, elated SUICIDE Do you ever wish you won’t wake up? Does it ever seem that life isn’t worth it? HOMICIDE Is there someone who deserves to be hurt?
MEDICAL ENCOUNTER Comprehensive global assessment Focused selected assessment
IN PRACTICE, MOST ENCOUNTERS ARE FOCUSED Accordingly the formal mental status exam is often limited to an assessment of COGNITION Further cognition is often assessed solely using: ORIENTATION
TO ORIENT To understand one’s relationship to the environment
Person Place Time Situation “Oriented X 3” “O X3”
Person Place Time Situation “Oriented X 3” “O X3” “Oriented X 4” “OX4”
ORIENTATION ASSESSES: “Oriented X 3” “O X3” “Oriented X 4” “OX4” Person Place Time Situation “Oriented X 3” “O X3” “Oriented X 4” “OX4” • language • perception • reasoning • remote memory • recent memory ORIENTATION ASSESSES:
Mini Mental Status More precise Less precise More comprehensive Less comprehensive Shorter Examiner norms More precise More comprehensive Longer Statistical norms Mini Mental Status Orientation Full mental status Neuropsychological Testing
MINI MENTAL STATE EXAM ADVANTAGES brief (10 min), systematic bedside instrument wide recognition among physicians since it is standardized, the score it yields is meaningful to physicians familiar with it DISADVANTAGES specific deficits may be ignored if the overall score is not low (less than 25 out of 30) the global score has no localizing valve repeated use with intact patients produces a mechanical transaction
Examiner uses paper and pencil Total of 30 points orientation (10) recent memory (3) attention (3) calculation, spell backward (5) name, read, repeat (4) write (1) constructional ability (1) ideomotor praxis (3) Not timed
What is the (year) (season) (date) (day) (month)? Where are we? (state) (county) (city) (hospital) (floor)(10) Ask pt to repeat three objects - give one per second. Number repeated first trial = score (3). Present till all repeated or 6 presentations. Serial 7’s - 5 subtractions (93, 86, 79, 72, 65) (5). Score number of correct answers or spell “world” backward, score is number of letters in correct order. “dlorw” is 3 points.
Ask the patient to name a watch and a pencil. (2) Ask the patient to say “No ifs, ands or buts” (1). Ask the patient to recall the three words (3). Ask the pt to read and follow the command: “Close your eyes”. Score (1 ) only if closes eyes. Ask the pt to write a sentence. It must have a subject and a verb and be sensible. Ignore grammar and punctuation (1).
Place a piece of paper where the patient can reach it with either hand. Ask him/her to: (1) pick it up, (2) fold it in half, (3) lay it on the floor. 1 pt for each step executed correctly (3). Ask the patient to copy a drawing of intersecting pentagons. All 10 angles must be present and two must intersect to create a 4 sided figure. Ignore tremor and rotation (1).
Normals can be expected to score > 25 However, even with > 25, if 0/3 or 1/3 for recent memory or problems with naming, repeating, writing or reading suggest focal deficits. It is most sensitive to disturbances which broadly effect function, it may miss subtle, focal problems.
You may not always do a MMS: Too little time Patient becomes agitated at challenge However, even without an MMS Interacting with the patient and obtaining a history have provided information to write up a mental status exam Lesson: YOU DO NOT HAVE TO DO AN MMS TO THOROUGHLY EXAM A PT
