Higher Mental Functions: Step-by-Step Clinical Assessment

---

STEP 1 — CONSCIOUSNESS

Before assessing any higher function, confirm the patient is aroused and alert. All cognitive testing is meaningless in an unresponsive or drowsy patient. — Plum and Posner's Diagnosis and Treatment of Stupor and Coma; Goldman-Cecil Medicine, 26th Ed.

---

1A. AVPU Scale (Rapid Bedside Screen)

---

1B. Glasgow Coma Scale (GCS)

Eye Opening (E) — Max 4

---

Motor Response (M) — Max 6

---

Verbal Response (V) — Max 5

• 13–15 = Mild brain dysfunction
• 9–12 = Moderate brain dysfunction
• ≤ 8 = Severe — consider intubation / airway protection

Plum & Posner: "No scale is adequate for all patients; the best policy is to describe the findings explicitly."

---

1C. Ranchos Los Amigos Scale (RLA) — for Recovering Patients (TBI/Post-Coma)

---

STEP 2 — ORIENTATION

"Impairment in orientation to time, place, and person is associated with cognitive disorders." — Kaplan & Sadock's Synopsis of Psychiatry

---

• "Can you tell me your full name?"
• "Do you know who I am? What is my role?"
• "Who are these people with you?"

• "Can you tell me where you are right now?"
• "What city/town are we in?"
• "What is the name of this building/hospital?"
• "What floor are we on?"

• "What is today's date?"
• "What month is it?"
• "What year is it?"
• "What day of the week is it?"
• "What season of the year is it?"

Neuroanatomy through Clinical Cases: "You should never write 'A&Ox2' — this is ambiguous and makes it hard to know what the patient's true mental status was."

---

STEP 3 — ATTENTION & CONCENTRATION

Must be assessed BEFORE memory and higher functions — an inattentive patient will fail all subsequent tests due to attention deficit, not true cognitive impairment. — Neuroanatomy through Clinical Cases, 3rd Ed.

---

---

STEP 4 — MEMORY

---

---

"There is no substitute for specifically testing memory on mental status exam — many patients appear to have intact memory in casual discussion yet have significant deficits when explicitly tested." — Neuroanatomy through Clinical Cases

1. Say: "I am going to tell you three things, and I want you to remember them. Apple. Table. Penny."
2. Ask patient to repeat all three immediately — confirms registration.
3. Continue the rest of the exam (3–5 minutes of distraction).
4. Then ask: "Can you recall those three items I asked you to remember?"

• 3/3 after 5 min = normal
• 2/3 = borderline
• 0–1/3 = significant impairment — suspect limbic/hippocampal pathology

---

• "When is your birthday? Where were you born?"
• "What is your mother's maiden name?"
• "Who is the current President/Prime Minister?"
• "What year did World War II end?"

---

STEP 5 — SPEECH & LANGUAGE

---

• Fluency — Is speech effortful and sparse (non-fluent) or flowing freely (fluent)?
• Prosody — Is melody/intonation normal?
• Paraphasias — Wrong words (verbal paraphasia) or wrong sounds (phonemic paraphasia)?
• Articulation — Dysarthria (slurred/mechanical distortion)?

---

• 1-step: "Close your eyes."
• 2-step: "Point to the window, then touch your nose."
• 3-step: "Pick up the paper with your right hand, fold it in half, and put it on the floor."

---

• Easy (high-frequency words) first → harder (low-frequency) second.
• Test parts of objects (the clip of the pen, the face of the watch).

---

---

• Show a written command: "CLOSE YOUR EYES" — does the patient read it AND obey it?
• Ask patient to read a short paragraph aloud.
• Test reading comprehension separately from aloud reading.

---

• Ask patient to write their name.
• Ask patient to write a complete sentence of their own choice.
• Agraphia = inability to write; may parallel aphasia or be dissociated.

---

STEP 6 — PERCEPTION (GNOSIS)

"Agnosia — the inability to recognise and interpret the significance of sensory impressions — is associated with organic brain diseases." — Kaplan & Sadock's Synopsis

---

---

STEP 7 — PRAXIS (MOTOR PLANNING)

"The ability to carry out commanded tasks (praxis) is pertinent to the evaluation of several aspects of cortical function." — Adams & Victor's Principles of Neurology, 12th Ed.

• "Show me how you would hammer a nail."
• "Show me how you would brush your teeth."
• "Show me how you would blow out a candle."
• "Show me how you would throw a die."

• "Copy this drawing." (Show interlocking pentagons, a cube, or a clock face)
• "Draw a clock face with all 12 numbers and set the hands to 10 past 11."

---

STEP 8 — HIGHER COGNITIVE FUNCTIONS

---

• "How much is 7 + 8?"
• "How much change from £1 if something costs 65p?"
• Simple multiplication, subtraction.

---

• Concrete interpretation = early dementia, frontal lobe dysfunction, or low education
• Note cultural context before concluding pathology.

---

• "Draw a map of the room we're in."
• "Copy these overlapping pentagons." (from MMSE)
• "Bisect this line with a mark in the exact middle."
• Left-sided neglect in bisection = right hemisphere lesion

---

• Insight question: "Why are you in the hospital? Do you think you have any problems with your memory?" Impaired insight and judgment = frontal lobe or diffuse cortical dysfunction.

---

Complete Assessment of Higher Mental Functions

Step-by-Step Clinical Guide with MMSE

---

Before you begin: Ensure the room is quiet, lighting is adequate, the patient has their glasses/hearing aids if needed. Introduce yourself. Note the patient's language, education level, and baseline before interpreting results. — Harrison's Principles of Internal Medicine, 22nd Ed.

---

▶ STEP 1 — CONSCIOUSNESS & WAKEFULNESS

"Level of consciousness is the patient's relative state of awareness of self and the environment, ranging from fully awake to comatose." — Harrison's Principles of Internal Medicine

What to Observe First (Before Asking Anything):

• Does the patient open their eyes spontaneously?
• Do they respond to your voice as you enter the room?
• Are they looking around purposefully or staring blankly?

Describe consciousness using these terms:

Glasgow Coma Scale (GCS) — Score formally if any doubt:

• Say the patient's name normally → if no response, speak loudly → if still no response, apply pain (nail-bed pressure or supraorbital pressure)

• Ask: "What is your name? Where are you? What year is it?"

• Say: "Hold up two fingers / squeeze my hand"
• If no response → apply pain to nail bed

• 13–15 = Mild impairment
• 9–12 = Moderate impairment
• ≤ 8 = Severe — airway at risk

Note: GCS ≤ 8 — proceed to emergency management. Do NOT proceed to cognitive testing in a deeply unconscious patient.

---

▶ STEP 2 — WAKEFULNESS / AROUSAL (Alertness Assessment)

"The evaluation of higher mental function presupposes that the patient has intact arousal and alertness." — Goldman-Cecil Medicine

1. Walk into the room normally — does the patient look at you? → Alert
2. Call their name — do they respond? → Voice
3. Press firmly on the nail bed or trapezius squeeze — any movement? → Pain
4. No response to any of above → Unresponsive

Only proceed to Steps 3–12 if the patient scores Alert or can reliably respond to Voice.

---

▶ STEP 3 — ORIENTATION

"Orientation to time is usually the first to be affected in a variety of conditions." — Harrison's Principles of Internal Medicine

"Greater significance is given to difficulties of person than to difficulties of time and place." — Kaplan & Sadock's Synopsis of Psychiatry

How to ask — say exactly these questions:

• "Can you tell me your full name?"
• "Do you know who I am? What is my job?"
• "Who are these people with you — can you identify them?"

• "Where are you right now?"
• "What is the name of this building?"
• "What city/town are we in?"
• "What country are we in?"
• "What floor of the building are we on?"

• "What is today's date?"
• "What day of the week is it?"
• "What month is it?"
• "What year is it?"
• "What season is it?"

---

▶ STEP 4 — ATTENTION & CONCENTRATION

"Because attention is so important, it is essential to evaluate it toward the beginning of the examination. Impaired attention may cause poor performance on all other tests." — Neuroanatomy through Clinical Cases, 3rd Ed.

Test 1 — Digit Span (Forward)

• 3 – 8 – 2
• 5 – 7 – 1 – 4
• 6 – 3 – 9 – 2 – 8
• 4 – 7 – 1 – 9 – 5 – 3

Test 2 — Digit Span (Backward)

Test 3 — Serial 7s

• Normal = <2 errors in 5 subtractions
• If patient cannot manage 7s, try Serial 3s from 20, or spell "WORLD" backward (D-L-R-O-W)

Test 4 — Months of the Year Backward

---

▶ STEP 5 — MEMORY

"There is no substitute for specifically testing memory on mental status exam. Many patients appear to have intact memory in casual discussion yet have significant deficits when tested." — Neuroanatomy through Clinical Cases, 3rd Ed.

A. Immediate Memory (Registration)

• If cannot repeat → say them again (up to 3 trials)
• Record number of trials needed

---

B. Recent Memory (Short-term / Anterograde)

• Recalls with cue = encoding is intact, retrieval is impaired (frontal)
• Cannot recall even with cue = encoding failure (hippocampal/medial temporal)

---

C. Remote Memory (Long-term)

• "When and where were you born?"
• "What are your children's names and birthdays?"
• "What did you have for breakfast this morning?" (very recent remote)

• "Who is the current Prime Minister / President?"
• "What major event happened in [year relevant to patient's era]?"

---

▶ STEP 6 — SPEECH

"Speech is assessed by observing articulation, rate, rhythm, and prosody (changes in pitch and accentuation of syllables and words)." — Harrison's Principles of Internal Medicine

---

▶ STEP 7 — LANGUAGE

"Language is assessed by observing the content of verbal and written output, response to spoken commands, and ability to read." — Harrison's Principles of Internal Medicine

1. Fluency (from observation in Step 6)

• Fluent = smooth, effortless, normal output volume (even if content is wrong) → Wernicke-type
• Non-fluent = effortful, sparse, telegraphic → Broca-type

2. Comprehension

• 1-step: "Close your eyes."
• 2-step: "Point to the door, then touch your left ear."
• 3-step: "Take this paper with your right hand, fold it in half, and place it on the table."

3. Naming

• Easy: pen, watch, shoe, cup
• Harder: belt buckle, knuckle, lapel, stethoscope diaphragm

4. Repetition

• "No ifs, ands, or buts" (tests grammatical function words)
• "The quick brown fox jumped"
• "Methodist Episcopal" (tests articulation complexity)

5. Reading

• Show a written card: "CLOSE YOUR EYES"
  • Patient must read it AND obey it (tests reading comprehension, not just reading aloud)
• Ask patient to read a short paragraph aloud.
• Ask patient what they understood from what they read.

6. Writing

• "Please write your full name."
• "Now write a complete sentence — anything you like."

---

▶ STEP 8 — READING (Formal Assessment)

• Show a short paragraph and ask: "Please read this and then tell me what it said."
• Test reading comprehension separately from reading aloud
• Alexia without agraphia = left occipital + corpus callosum lesion (patient can write but cannot read their own writing)
• Alexia with agraphia = dominant angular gyrus lesion

---

▶ STEP 9 — CALCULATION

"Calculation ability is assessed by carrying out computations appropriate to the patient's age and education." — Harrison's Principles of Internal Medicine

• "How much is 5 + 6?"
• "How much is 15 minus 8?"

• "How much is 7 × 8?"
• "If you have £1.00 and you spend 35 pence, how much change do you get?"

• Serial 7s from 100 (already done in attention step — record same score here)

---

▶ STEP 10 — PERCEPTION (GNOSIS)

"Agnosia — inability to recognise and interpret the significance of sensory impressions — is associated with organic brain disease." — Kaplan & Sadock's Synopsis of Psychiatry

Visual Gnosis:

• Pen, key, comb, coin
• If cannot name → ask them to demonstrate use
  • Can demonstrate use but cannot name = visual agnosia (not aphasia)

Facial Recognition (Prosopagnosia):

• Cannot recognise faces = prosopagnosia → bilateral ventral occipitotemporal lesion

Tactile Gnosis (Astereognosis):

• Cannot identify by touch with intact sensation = astereognosis → contralateral parietal lesion

Finger Agnosia:

Anosognosia (Self-perception):

---

▶ STEP 11 — REASONING & ABSTRACT THINKING

"Abstract thought can be tested by asking the patient to describe similarities between various objects or concepts." — Harrison's Principles of Internal Medicine

Similarities (Abstract vs. Concrete):

• Apple and orange → (abstract: both fruits; concrete: both have skin)
• Table and chair → (abstract: both furniture; concrete: both made of wood)
• River and road → (both are ways to travel/move)

• Abstract answer = normal
• Concrete/functional answer = early dementia, frontal dysfunction
• Unable to find any similarity = significant impairment

Proverb Interpretation:

• "A rolling stone gathers no moss."
• "Don't cry over spilt milk."
• "People in glass houses should not throw stones."
• Abstract interpretation = understanding the metaphorical meaning = normal
• Literal interpretation = "It means a stone that rolls has no moss on it" = concrete thinking = frontal or diffuse cortical dysfunction

Note: Always consider cultural background and education before concluding pathology.

---

▶ STEP 12 — JUDGMENT & INSIGHT

"Abnormalities of insight and judgment are usually detected during the interview; a more detailed assessment can be elicited by asking the patient to describe responses to situations." — Harrison's Principles of Internal Medicine

Judgment:

• "What would you do if you found a wallet on the street?"
• "What would you do if you smelled smoke in a cinema?"
• "If you found a stamped, sealed, addressed envelope on the floor, what would you do?"

Insight:

• "Do you think there is anything wrong with your memory?"
• "Why are you in the hospital today?"
• "Do you think you need help managing your daily affairs?"

---

---

▶ MINI MENTAL STATE EXAMINATION (MMSE)

Folstein et al., 1975 — Standard Bedside Cognitive Screen

"A 30-point standardised screening tool; ~85% sensitive and 85% specific for moderate-to-severe dementia. Takes less than 10 minutes." — Harrison's Principles of Internal Medicine; Bradley and Daroff's Neurology in Clinical Practice

---

DOMAIN 1 — ORIENTATION (10 points)

Time (5 points)

Place (5 points)

---

DOMAIN 2 — REGISTRATION (3 points)

• Score 1 point per object correctly repeated on first attempt (maximum 3).
• If patient does not get all 3 on first try → repeat them up to 3 trials until they learn all 3 (for later recall) — but only score what they said on the first attempt.

---

DOMAIN 3 — ATTENTION & CALCULATION (5 points)

---

DOMAIN 4 — RECALL (3 points)

---

DOMAIN 5 — LANGUAGE (8 points)

• Spontaneously generated (not dictated)
• Contain a subject and a verb
• Make sense

---

DOMAIN 6 — VISUOSPATIAL CONSTRUCTION (1 point)

• Both pentagons have 5 sides each
• They overlap correctly, creating a 4-sided figure in the intersection

---

MMSE SCORING SUMMARY

Interpretation:

Important corrections:

• Adjust for age: Scores drop slightly with age (mean ~27 for age 65–74 with secondary education)
• Adjust for education: Low education (< 8 years schooling) → lower expected scores; high education (≥ 13 years) → higher expected scores
• A score of 24 in an illiterate elderly patient may be normal; the same score in a professor is significant — Bradley and Daroff's Neurology in Clinical Practice

COMPLETE HIGHER MENTAL FUNCTION ASSESSMENT

Full Examiner–Patient Script: What to Say, What to Do, How to Score, How to Interpret

---

Setting up: Sit across from the patient at eye level. Ensure quiet environment. Check the patient has glasses/hearing aids if needed. Say: "Good morning/afternoon. My name is [your name]. I am going to ask you some questions and give you a few simple tasks. Please do your best — there are no right or wrong answers, just try your best. Are you comfortable?"

---

---

═══ PART 1: CONSCIOUSNESS & WAKEFULNESS ═══

---

🔹 BEFORE YOU SPEAK — OBSERVE FOR 10 SECONDS

• Are their eyes open? → Spontaneous eye opening
• Are they looking at you? → Purposeful gaze
• Are they moving? → Spontaneous motor activity
• Are they slumped, stiff, or limp?

---

🔹 STEP 1A — VERBAL STIMULUS TEST

"Hello, [patient's name]. Can you hear me?"

"[NAME]! Open your eyes! Can you hear me?"

---

🔹 STEP 1B — GLASGOW COMA SCALE (GCS)

---

EYE OPENING

---

VERBAL RESPONSE

"What is your name? Where are you? What year is it?"

---

MOTOR RESPONSE

"Squeeze my fingers. Now hold up two fingers."

---

GCS CALCULATION:

✅ If GCS = 15 (fully awake, responsive): Proceed to all steps below. ⛔ If GCS ≤ 12: Cognitive testing is unreliable — address medical emergency first.

---

---

═══ PART 2: ORIENTATION ═══

---

🔹 STEP 2 — ORIENTATION TO PERSON, PLACE & TIME

"I'm going to ask you a few simple questions about yourself and your surroundings. Please answer as best you can."

---

ORIENTATION TO PERSON

"Can you tell me your full name?"

"Can you tell me how old you are?"

"Do you know who I am? What is my role?"

---

ORIENTATION TO PLACE

"Can you tell me where we are right now — what kind of place is this?"

"What is the name of this hospital / building?"

"What city or town are we in?"

"What floor are we on?"

---

ORIENTATION TO TIME

"I'd like to ask you about the date now. What year is it currently?"

"What season of the year is this?"

"What month are we in?"

"What is today's date — the number?"

"What day of the week is it today?"

---

SCORING ORIENTATION:

INTERPRETATION:

Always write exact wrong answers. Example: "Patient gave year as 1985, did not know month or day, but correctly identified hospital name and city." Never just write "disoriented x2."

---

---

═══ PART 3: ATTENTION & CONCENTRATION ═══

---

🔹 STEP 3A — DIGIT SPAN FORWARD

"I am going to say some numbers. When I finish, repeat them back to me in the same order. Ready?"

---

🔹 STEP 3B — DIGIT SPAN BACKWARD

"Now I will say more numbers, but this time repeat them to me BACKWARD — the last number first. So if I say 2 — 4, you say 4 — 2. Ready?"

---

🔹 STEP 3C — SERIAL 7S

"I'd like you to start at 100 and keep subtracting 7. So 100 take away 7 is 93, then take away 7 again, and keep going. Go as far as you can. Begin."

• Serial 3s from 20: "Start at 20 and keep taking away 3." (20 → 17 → 14 → 11 → 8)
• OR spell "WORLD" backward: "Spell the word WORLD backward." → D-L-R-O-W

---

🔹 STEP 3D — MONTHS OF YEAR BACKWARD

"Can you name the months of the year backward, starting from December?"

---

ATTENTION INTERPRETATION:

⚠️ If attention is severely impaired, all subsequent tests will be unreliable. Document this and note that further cognitive testing is limited by attentional deficit.

---

---

═══ PART 4: MEMORY ═══

---

🔹 STEP 4A — REGISTRATION (Immediate Memory)

"I am going to name three objects. Listen carefully, and when I have finished, repeat them back to me. Also, try to remember them — I will ask you again in a few minutes."

"Apple… Table… Penny"

• If they miss one → say all three again
• Repeat up to 3 trials until all three are learned
• ONLY score what they say on the very first attempt (for MMSE)
• Record: "Learned in 2 trials" etc.

---

🔹 STEP 4B — SHORT-TERM / RECENT MEMORY (After ~5 minutes)

"Do you remember those three words I asked you to remember a few minutes ago? What were they?"

"One of them was a fruit… can you remember it now?" "One was a piece of furniture…" "One was a coin…"

---

🔹 STEP 4C — REMOTE MEMORY

"Now I'd like to ask you about some things from the past."

"When is your birthday — day, month, and year?" "Where were you born?" "What was your mother's maiden name?"

"Who is the current Prime Minister / President of this country?" "Can you name any major world event that happened in your lifetime that you remember well?"

---

---

═══ PART 5: SPEECH ═══

---

🔹 STEP 5 — OBSERVE SPONTANEOUS SPEECH

"Tell me in your own words what brought you to the hospital today." (or: "Tell me about your day.")

---

---

═══ PART 6: LANGUAGE ═══

---

🔹 STEP 6A — COMPREHENSION

"Please close your eyes."

"Point to the window, then touch your left ear."

"Take this paper with your right hand, fold it in half, and place it on the floor."

"Listen carefully: John was hit by Mike. Is Mike hurt?"

---

🔹 STEP 6B — NAMING

"What is this called?" Patient: "A pen." ✅

"What is this?" Patient: "A watch." ✅

"What is this part of the watch called?" (point to the strap, buckle, face, hands) "What is this part of the pen?" (cap, clip, nib, barrel)

---

🔹 STEP 6C — REPETITION

"I want you to repeat exactly what I say, word for word:"

"No ifs, ands, or buts."

"The quick brown fox jumped over the lazy dog." "Methodist Episcopal." (tests complex articulation)

• Cannot repeat despite understanding = conduction aphasia (arcuate fasciculus lesion)
• Distorts words = phonemic paraphasia
• Substitutes words = verbal paraphasia

---

🔹 STEP 6D — READING (Written Command)

CLOSE YOUR EYES

"Please read what is written on this card and do what it says."

Show a short paragraph: "Please read this aloud." Then: "What did it say?"

---

🔹 STEP 6E — WRITING

"Please write a sentence — any sentence of your choice. It should be a complete sentence with a subject and an action."

• Has a subject
• Has a verb
• Makes sense
• Is spontaneously produced

• Cannot produce a sentence = severe aphasia
• Writes only their name = agraphia
• Misspells every word phonetically = phonological agraphia

---

---

═══ PART 7: READING (Extended) ═══

"I'm going to show you a short paragraph. Please read it carefully, and then tell me in your own words what it said."

"Now tell me what that passage was about."

• Alexia = cannot read despite intact vision
• Reads aloud correctly but cannot explain = reading without comprehension

---

---

═══ PART 8: CALCULATION ═══

---

🔹 STEP 8A — SIMPLE ARITHMETIC

"I'd like to test your arithmetic. No need for pen and paper — just in your head."

"How much is 7 plus 8?" Correct answer: 15 ✅

"How much is 25 minus 9?" Correct answer: 16 ✅

"How much is 6 times 7?" Correct answer: 42 ✅

---

🔹 STEP 8B — PRACTICAL CALCULATION

"If you went to the shop and bought something for 65 pence, and you paid with a £1 coin, how much change would you get back?" Correct answer: 35 pence ✅

"If a shirt costs £15 and there is a 20% discount, how much would you pay?" Correct answer: £12 ✅ (use simpler version based on education level)

---

🔹 STEP 8C — SERIAL 7S (already done in attention — record same score here)

---

CALCULATION INTERPRETATION:

⚠️ Always adjust expectations for education level. A patient with 4 years of schooling cannot be labelled acalculic for failing multiplication.

---

---

═══ PART 9: PERCEPTION (GNOSIS) ═══

---

🔹 STEP 9A — VISUAL GNOSIS

"What is this object? What is it used for?"

"Can you show me how you would use it?"

• Cannot name BUT can demonstrate use = visual agnosia (object meaning lost, not motor)
• Cannot name AND cannot demonstrate = severe impairment

---

🔹 STEP 9B — FACIAL RECOGNITION (Prosopagnosia)

"Do you recognise this person? Who is it?"

---

🔹 STEP 9C — TACTILE GNOSIS (Astereognosis)

"I am going to place an object in your hand. Please close your eyes and tell me what it is just by feeling it — don't look."

---

🔹 STEP 9D — FINGER GNOSIS (Finger Agnosia)

"Please close your eyes and hold out your hand flat. I am going to touch one of your fingers, and I want you to tell me which finger I am touching."

---

🔹 STEP 9E — ANOSOGNOSIA (Awareness of Own Deficit)

"Can you move your left arm for me?"

"Do you know that your left arm is not moving properly?" "How long has your arm been like this?"

---

---

═══ PART 10: REASONING & ABSTRACT THINKING ═══

---

🔹 STEP 10A — SIMILARITIES

"I'm going to name two things, and I'd like you to tell me how they are alike — what do they have in common?"

"How are an apple and an orange alike?"

"How are a table and a chair alike?"

"How are a train and a bicycle alike?"

---

🔹 STEP 10B — PROVERB INTERPRETATION

"I am going to say a common saying, and I'd like you to tell me what it means — not what the words say literally, but the deeper meaning."

"A rolling stone gathers no moss."

"Don't cry over spilt milk."

"People in glass houses should not throw stones."

---

REASONING INTERPRETATION:

⚠️ Cultural note: Always ask if the patient knows the proverb first. Different cultures use different sayings. If unfamiliar, try a culturally relevant saying or use similarities only.

---

---

═══ PART 11: JUDGMENT & INSIGHT ═══

---

🔹 STEP 11A — JUDGMENT

"I'd like to ask you a few questions about what you would do in certain situations."

"If you found a sealed, stamped envelope on the pavement with an address written on it, what would you do?"

"If you were in a cinema and you smelled smoke, what would you do?"

"If you found a wallet full of money in a shop, what would you do?"

---

🔹 STEP 11B — INSIGHT

"Do you think there is anything wrong with your memory at the moment?"

"Do you think you need any help with your daily activities?"

"Why have you come to the hospital today?"

---

JUDGMENT & INSIGHT INTERPRETATION:

---

---

═══ PART 12: VISUOSPATIAL CONSTRUCTION ═══

---

🔹 STEP 12A — COPY INTERLOCKING PENTAGONS (MMSE)

"I'd like you to copy this drawing as accurately as you can."

• Both figures have 5 sides
• They intersect correctly creating a 4-sided overlap
• Lines reasonably straight (tremor acceptable)

---

🔹 STEP 12B — CLOCK DRAWING TEST (Bonus / Extended)

"Please draw a clock face. Put in all 12 numbers and then set the hands to show 10 minutes past 11."

• Circle drawn
• 12 numbers placed correctly (12 at top, numbers spaced evenly)
• Two hands pointing to 11 and 2 (10 past 11)

---

---

WHEN TO ASSESS THE MMSE — Complete Clinical Guide

---

THE CORE PRINCIPLE

"The MMSE is ~85% sensitive and 85% specific for making the diagnosis of dementia that is moderate or severe. It is best used for baseline assessments of dementia, rather than delirium." — Harrison's Principles of Internal Medicine, 22nd Ed.; Rosen's Emergency Medicine

---

═══ WHEN TO USE THE MMSE ═══

---

✅ INDICATION 1 — Complaint of Memory Loss

• "I keep forgetting things."
• "My family says my memory is getting worse."
• "I can't remember what I did yesterday."

---

✅ INDICATION 2 — Suspected Dementia

• Patient repeats the same question multiple times in one consultation
• Cannot recall their medications, medical history, or recent events
• Family member says: "He/she is forgetting names, getting lost, not managing finances"
• Patient appears confused during normal conversation

---

✅ INDICATION 3 — Monitoring Established Dementia (Serial Testing)

---

✅ INDICATION 4 — Pre-Operative Assessment (Before Major Surgery)

• Major cardiac surgery
• Orthopaedic surgery (hip/knee replacement)
• Any surgery requiring general anaesthesia

• Pre-existing cognitive impairment is a major risk factor for Post-Operative Cognitive Dysfunction (POCD) and post-operative delirium
• Gives a pre-op score to compare with if the patient becomes confused post-operatively
• Helps anaesthesia and surgical teams plan accordingly

---

✅ INDICATION 5 — New Confusion in a Hospitalised Patient

• Confused overnight
• Agitated or pulling out lines
• Not knowing where they are

⚠️ Important caveat: If delirium is suspected (acute onset, fluctuating, inattentive), the MMSE is not the right test for diagnosing delirium. Use the CAM (Confusion Assessment Method) for delirium. MMSE is for baseline dementia screening — "the MMSE is best used for baseline assessments of dementia, rather than delirium." — Rosen's Emergency Medicine Use MMSE in the same patient after the delirium resolves to assess underlying baseline cognition.

---

✅ INDICATION 6 — Stroke Patient — Post-Stroke Cognitive Assessment

• Vascular dementia is the second commonest dementia — strokes are a major cause
• Establishes post-stroke cognitive baseline
• Guides rehabilitation planning
• Note: MoCA is preferred over MMSE for post-stroke patients because MMSE misses executive dysfunction, which is prominent in vascular dementia

---

✅ INDICATION 7 — Psychiatric Disorder with Cognitive Symptoms

• Depression saying "I can't think clearly, my memory is terrible"
• Schizophrenia with disorganised thinking
• Bipolar disorder with cognitive complaints

---

✅ INDICATION 8 — Medico-Legal / Capacity Assessment

• Make their own medical decisions (consent for surgery, refuse treatment)
• Manage their own finances
• Make a valid will

---

✅ INDICATION 9 — Elderly Patient Annual Wellness Check

• Family history of dementia
• Hypertension, diabetes, hyperlipidaemia (vascular risk factors)
• History of head injury
• Known mild cognitive impairment (MCI)

---

═══ WHEN NOT TO USE THE MMSE ═══

---

❌ DO NOT USE in Active Delirium

---

❌ DO NOT USE When GCS < 15

---

❌ DO NOT USE as the Only Test for Mild Cognitive Impairment (MCI)

"In most patients with MCI and some with clinically apparent Alzheimer's disease, bedside screening tests may be normal — a more challenging neuropsychological test will be required." — Harrison's Principles of Internal Medicine

---

❌ DO NOT USE Without Adjusting for Education and Age

• A patient with 4 years of schooling scoring 22/30 may be normal for them
• A professor scoring 26/30 may already have significant pathology
• Illiterate patients will fail the writing and reading sections regardless of cognition Rule: Always adjust cut-off scores for education and age before interpreting.

---

❌ DO NOT USE for Assessing Executive Function
