Dementia — Advanced Nursing Guide

Dementia: Core Definition & Epidemiology

Dementia is a clinical syndrome of progressive cognitive decline severe enough to impair daily functioning. It is not a single disease — it is an umbrella term covering multiple pathological subtypes. Globally affects 57 million; GCC nations face a rapidly rising burden linked to ageing populations and the vascular risk factor epidemic (diabetes, hypertension, obesity).

Alzheimer's Disease (AD) 60–70% of cases

Pathophysiology

Amyloid plaques (extracellular β-amyloid) — earliest biomarker
Neurofibrillary tangles (intracellular hyperphosphorylated tau)
Acetylcholine deficit → basis for pharmacotherapy
Hippocampal atrophy first, then parietal/temporal

Clinical Features

Insidious onset, gradual progression
Memory loss is predominant early feature (episodic memory first)
Later: aphasia, apraxia, agnosia, executive dysfunction

Investigations

CT/MRI: medial temporal lobe/hippocampal atrophy
MMSE, MoCA for staging
CSF: low Aβ42, high total-tau / phospho-tau
PET amyloid imaging (specialist centres)

Vascular Dementia (VaD) 15–20% of cases

Pathophysiology

Cerebrovascular disease: multiple infarcts, single strategic infarct, or diffuse white matter disease (Binswanger's)
Vascular risk factors: HTN, DM, smoking, AF, hyperlipidaemia

Clinical Features

Stepwise decline rather than gradual
Focal neurological signs common
Gait disturbance, urinary incontinence early
Executive dysfunction may precede memory loss

Investigations

MRI: white matter hyperintensities (leukoaraiosis), lacunar infarcts
Vascular risk factor workup: HbA1c, lipids, BP monitoring, ECG (AF)
Carotid Doppler if indicated

Lewy Body Dementia (LBD) ~5%

Core Features (must have ≥2 for probable LBD)

Fluctuating cognition with pronounced variations in attention
Visual hallucinations (recurrent, detailed, well-formed)
Parkinsonism (spontaneous, not drug-induced)
REM sleep behaviour disorder

⚠ CRITICAL: Antipsychotic Sensitivity

Patients with LBD have severe neuroleptic sensitivity — even small doses of antipsychotics (esp. haloperidol, chlorpromazine) can cause irreversible parkinsonism, severe NMS-like reactions, accelerated cognitive decline, and death. Antipsychotics are CONTRAINDICATED or used only with extreme caution.

Investigations

DaTSCAN (dopamine transporter SPECT) — abnormal in LBD, normal in AD
Polysomnography for REM sleep behaviour disorder

Frontotemporal Dementia (FTD)

Key Distinctions from AD

Younger onset (50s–60s vs 70s+ in AD)
Personality and behaviour change predominates early — disinhibition, apathy, social inappropriateness, hypersexuality, compulsive rituals
Memory relatively preserved early
Language variants: progressive non-fluent aphasia, semantic dementia
Frontal/temporal lobe atrophy on MRI; pick bodies (tau)

FTD vs Alzheimer's

Feature	FTD	AD
Onset age	Usually <65	Usually >65
Early symptom	Behaviour/personality	Episodic memory
MRI atrophy	Frontal/temporal	Medial temporal
MMSE	May be relatively preserved	Early impairment

Mixed Dementia & Reversible Causes

Mixed Dementia

Most commonly AD + vascular pathology. Very prevalent in post-mortem studies. Clinical features overlap. Manage both vascular risk factors and cognitive symptoms.

Reversible ("Potentially Treatable") Causes — MUST EXCLUDE

Hypothyroidism — TFTs mandatory in all
Vitamin B12 / folate deficiency
Neurosyphilis — syphilis serology
Subdural haematoma — CT head
Normal Pressure Hydrocephalus (NPH) — triad: gait apraxia + urinary incontinence + cognitive decline; CT: ventriculomegaly; shunting may help
Alcohol-related brain damage, Wernicke's encephalopathy (thiamine)
Medication toxicity (anticholinergics, benzodiazepines)
Depression (pseudodementia)
HIV dementia

NICE Diagnostic Pathway (NG97)

History from patient + carer (collateral history essential)
Cognitive assessment (MMSE or MoCA) at presentation
Blood tests to exclude reversible causes: FBC, U&E, LFTs, TFTs, glucose, B12/folate, calcium, syphilis serology
Structural brain imaging (CT or MRI) — exclude tumour, subdural, NPH, infarcts
Specialist memory clinic assessment if uncertain diagnosis
Diagnosis disclosure — compassionately, with written information
Care plan — including advance care planning discussion

GCC Clinical Note

DHA memory assessment clinics (Dubai) and equivalent DOH/SCFHS facilities follow adapted pathways. Arabic-language validated cognitive assessments (Arabic MMSE, Arabic MoCA) should be used where available but remain limited — a key practice gap noted in regional literature.

MMSE Limitations

Affected by education level, language, and literacy. Can miss mild impairment (ceiling effect). MoCA preferred for MCI. Not validated in Arabic without adaptation.

MoCA (Montreal Cognitive Assessment)

30-point scale — superior to MMSE for detecting mild cognitive impairment (MCI). Adds 1 point if <12 years education.

Visuospatial/executive: trail making, cube copy, clock drawing (5 pts)
Naming: 3 animals (3 pts)
Memory: 5 words, delayed recall (5 pts)
Attention: digit span, serial 7s, vigilance (6 pts)
Language: repetition, verbal fluency (3 pts)
Abstraction: 2 items (2 pts)
Orientation: 6 items (6 pts)

Semi-structured clinician interview. Rates 6 domains (memory, orientation, judgement, community affairs, home/hobbies, personal care).

No dementia0

Questionable / MCI0.5

Mild dementia1

Moderate dementia2

Severe dementia3

ACE-III (Addenbrooke's Cognitive Examination-III)

100-point scale. 5 domains: attention (18), memory (26), fluency (14), language (26), visuospatial (16). Threshold: <82 sensitive for dementia. More comprehensive than MMSE; useful for differentiating dementia subtypes.

Delirium vs Dementia Differentiator

Feature	Delirium	Dementia
Onset	Acute (hours–days)	Insidious (months–years)
Course	Fluctuating, often worse at night	Progressive, stable day-to-day
Attention	Markedly impaired — hallmark	Relatively preserved early
Consciousness	Clouded, altered	Alert until late stages
Reversibility	Usually reversible if cause treated	Mostly irreversible
Cause	Identifiable precipitant (infection, drugs, metabolic)	Neurodegenerative / vascular
Hallucinations	Visual/tactile, common	Less common except LBD
Assessment tools	4AT, CAM (Confusion Assessment Method)	MMSE, MoCA, ACE-III

Important: Delirium superimposed on dementia

Patients with dementia are at 3–5× higher risk of delirium. Always investigate for precipitants (sepsis, urinary retention, pain, medication changes, dehydration, constipation) when acute deterioration occurs.

Depression vs Dementia (Pseudodementia)

Depression can present as apparent cognitive impairment — "pseudodementia"
Depressed patients often complain more about memory than demented patients
"Don't know" answers common in depression vs. confabulation in dementia
Onset often related to life events; mood disturbance precedes cognitive symptoms
Cognitive symptoms often improve with antidepressant treatment
Important: Depression is also a risk factor for future dementia

Tools: GDS (Geriatric Depression Scale), PHQ-9, Cornell Scale for Depression in Dementia (for cognitively impaired)

Mental Capacity Act (MCA) — Capacity Assessment

5 Key Principles

Presumption of capacity
Right to be supported to make decisions
Right to make unwise decisions
Best interests standard if lacking capacity
Least restrictive option principle

Functional Test for Capacity

Patient must be able to: Understand information → Retain it → Weigh up information → Communicate decision.

GCC Note

UAE Federal Law No. 21 (2021) on Persons with Disabilities and patient rights legislation apply. Capacity is decision-specific and time-specific — assess for each decision.

Behavioural and Psychological Symptoms of Dementia (BPSD)

Occur in up to 90% of people with dementia at some stage. Major cause of carer burden and institutionalisation.

Affective Symptoms

Depression
Anxiety
Emotional lability
Apathy

Psychotic Symptoms

Paranoid delusions (theft, infidelity)
Visual hallucinations (esp. LBD)
Misidentification syndromes

Behavioural Symptoms

Agitation / aggression
Wandering / elopement
Sundowning (evening agitation)
Disinhibition
Sleep disturbance
Repetitive vocalisations

BPSD assessment tool: NPI (Neuropsychiatric Inventory) — rates 12 domains by frequency × severity. Always look for underlying causes (pain, infection, unmet needs, environmental triggers) before pharmacological intervention.

Cholinesterase Inhibitors Mild–Moderate AD

Drug	Dose & Route	Key Nursing Points
Donepezil (Aricept)	5mg ON → 10mg after 4–6 wks; oral	Take at bedtime (reduces insomnia side effects). Also approved for severe AD.
Rivastigmine (Exelon)	1.5mg BD → titrate; oral or transdermal patch	Patch preferred — fewer GI side effects. Change patch site daily. Also licensed for Parkinson's dementia.
Galantamine (Reminyl)	4mg BD → titrate; modified release OD	Take with food. Dual mechanism (AChE inhibitor + nicotinic receptor agonist).

Side Effects — Cholinergic Excess

GI: nausea, vomiting, diarrhoea, anorexia (most common, especially on initiation)
Cardiac: bradycardia, heart block — monitor HR/ECG; caution with sick sinus syndrome, conducting disorders
Muscle cramps, nightmares, urinary incontinence
Nausea management: take with food, titrate slowly, switch to patch formulation

Monitoring & Nursing Responsibilities

Baseline HR and ECG before initiation
Monitor HR at each medication review
Educate patient/family on GI side effects and when to seek help
Assess swallowing — liquid formulations available
GCC/Ramadan: donepezil can be taken at Iftar (evening meal) — maintains adherence during fasting

Memantine Moderate–Severe AD

Mechanism: NMDA receptor antagonist — reduces glutamate-mediated excitotoxicity. Used alone or in combination with donepezil in moderate-severe AD.

Start 5mg OD, increase by 5mg weekly to maintenance 20mg OD
Renal dose adjustment required (CrCl <30: max 10mg/day)
Side effects: dizziness, headache, constipation, somnolence — generally better tolerated than ChEIs
Avoid abrupt discontinuation — may cause clinical deterioration
Ramadan consideration: once-daily dosing can be given at Suhoor or Iftar

BPSD Non-Pharmacological Strategies ▼

Always attempt non-pharmacological approaches FIRST before considering medication for BPSD.

Structured Activities

Individualised meaningful activity programmes
Occupational therapy input
Reminiscence therapy — use photos, music, familiar objects from the past
Life story work — understand individual's history, preferences

Music & Sensory Approaches

Personalised music playlists — reduce agitation
Music therapy (RCT evidence for reducing BPSD)
Aromatherapy — lavender for anxiety (limited evidence)
Multi-sensory environments

Psychological Therapies

Validation therapy — acknowledge feelings, not reality-orientation
Cognitive stimulation therapy (CST) — group sessions
Behaviour management approaches — identify ABC (Antecedents, Behaviour, Consequences)

For Sundowning

Bright light therapy in the morning
Maintain structured daily routine
Avoid stimulants (caffeine) in afternoon/evening
Ensure sufficient daytime activity
Calm, low-stimulus environment in evenings
Adequate pain management (unmet need)

Communication Strategies

Use simple, short sentences
Approach calmly from the front
Allow time for response
Validate emotions — "I can see you're upset"
Distract and redirect rather than argue

Environmental Modifications

Increase natural light exposure
Visible clocks and calendars
Reduce unnecessary noise/stimulation
Familiar objects from home
Secure garden areas for safe wandering

Antipsychotic Use in BPSD — Cautions ▼

⚠ Antipsychotics in Dementia — Significant Risks

Use only when non-pharmacological measures have failed AND symptoms cause risk to the patient or others. Should be short-term only (review at 6 weeks), lowest effective dose.

Agents Used (with extreme caution)

Risperidone — only licensed antipsychotic for BPSD (aggression in AD); max 6 weeks; dose 0.25–1mg/day
Haloperidol — when sedation/rapid control needed; QTc monitoring essential
Quetiapine — often used (unlicensed) in clinical practice

Side Effects Monitoring

QTc prolongation → ECG at baseline and on treatment
Metabolic effects — glucose, lipids, weight
Extrapyramidal side effects, tardive dyskinesia
Falls risk — gait, orthostatic hypotension
Sedation — aspiration risk

Absolute CONTRAINDICATION in Lewy Body Dementia

Conventional (typical) antipsychotics — haloperidol, chlorpromazine — MUST NOT be used in LBD. Even atypical antipsychotics carry severe risk. Can cause: severe irreversible parkinsonism, NMS-like syndrome (hyperthermia, rigidity, autonomic instability), respiratory failure, death.

Black Box Warning (FDA/MHRA)

Antipsychotics in elderly dementia patients are associated with 1.6–1.7× increased risk of all-cause mortality, primarily from cardiac (sudden death, QTc) and cerebrovascular events (stroke, TIA). Inform family and document informed consent discussion.

Sleep Hygiene for Sundowning & Sleep Disorders

Consistent sleep-wake schedule
Limit naps to <30 min before 3pm
Bright light therapy (10,000 lux, 30–60 min morning)
Physical activity during daytime
No caffeine after noon

Comfortable, familiar bedroom environment
Dim lights in evening (melatonin priming)
Melatonin 0.5–2mg (unlicensed) — limited but sometimes used
Avoid benzodiazepines — paradoxical agitation, falls, delirium risk
Treat pain and urinary problems that disrupt sleep

Person-Centred Care

Kitwood's Personhood Model

Tom Kitwood (1997) — dementia care must preserve the personhood of the individual. The "VIPS" framework:

Valuing people with dementia and their carers
Individualised care recognising uniqueness
Personal perspective — the patient's viewpoint matters
Social environment enabling connection

Malignant social psychology (Kitwood) — depersonalising practices: ignoring, infantilising, withholding, treachery, disempowerment, stigmatising — all to be actively avoided.

Life Story Work

Gathering and using the patient's personal biography to guide individualised care:

Life history book/passport — photos, preferences, key life events
Understanding important roles (e.g., teacher, parent, professional)
Food preferences, cultural/religious practices, daily routines
Music and activities meaningful to the individual
In GCC context: includes prayer routines, Ramadan practices, language preferences, family roles

Therapeutic Communication in Dementia

Effective Approaches

Use simple, short sentences — one idea at a time
Speak slowly and clearly
Maintain eye contact at same level
Use patient's preferred name
Allow extra processing time — do not rush
Use touch (appropriate, consent) — reassuring
Validate emotions — acknowledge feelings not facts
Distract and redirect when distressed
Non-verbal communication is powerful

Approaches to Avoid

Do NOT argue or correct delusions/confabulations aggressively
Do NOT reality-orient in a blunt, distressing way — "Your husband has been dead for 10 years" causes repeated grief
Do NOT use childish language (infantilising)
Do NOT talk about the patient in their presence as if absent
Do NOT dismiss concerns: "You just asked me that"
Avoid overstimulating, noisy environments

Validation over Reality Orientation

If patient believes deceased spouse is still alive — respond to the emotional need. "You're missing him? Tell me about him." Meet them in their reality with compassion.

Safety Management in Dementia

Elopement/Wandering

Door alarms and coded keypads
GPS tracker devices (wrist/belt)
Safe wandering areas/secure gardens
Camouflage exit doors
ID bracelets
Register with Safe Return programmes

Falls Prevention

Multifactorial falls risk assessment
Medication review (antipsychotics, sedatives)
Hip protectors
Non-slip footwear
Good lighting, night lights
Environmental hazard removal
Low beds with floor cushioning
Supervised physical activity to maintain strength

Other Safety Issues

Fire safety — cooker monitors, smoke alarms
Driving — must report diagnosis; DVLA assessment
Financial safeguarding — lasting power of attorney early
Medication safety — monitored dosette boxes
Hot water temperature limiters
Telephone safety — scam vulnerability

Nutrition in Dementia

Weight loss and malnutrition common — assess BMI, MUST score regularly
Finger foods — maintain independence and dignity
Texture modification — IDDSI framework if dysphagia (SALT assessment)
Fortified foods and high-calorie supplements
Eat together — social eating improves intake
Colourful plates — improve visibility and appetite (contrast principle)
Ensure adequate hydration — offer fluids regularly

PEG Tube Ethical Considerations

Percutaneous endoscopic gastrostomy (PEG) feeding in advanced dementia is not associated with survival benefit or improved quality of life (Cochrane review evidence). Decisions should involve the patient's advance care plan, family, MDT and align with cultural/religious values. Document discussions fully.

Oral Care & Aspiration Prevention

Aspiration pneumonia is a leading cause of death in advanced dementia
Twice-daily oral care significantly reduces aspiration pneumonia risk
Mouth care with chlorhexidine or simple toothbrushing reduces oral bacteria load
Dental reviews — unmanaged dental pain is a common BPSD trigger
Assess swallowing at each meal (SALT referral if concerns)
Positioning: sit upright at 90° during eating
Stay upright 30 min post-meals
Modified diet and thickened fluids if SALT-recommended

Advance Care Planning in Dementia ▼

Why Early ACP Matters

Decision-making capacity progressively declines in dementia. Advance care planning should begin early, while capacity is retained. Avoids distress and conflicting decisions later.

Components of ACP in Dementia

Advance Decision to Refuse Treatment (ADRT) — legally binding refusal of specific treatment
DNACPR — document clearly, review regularly; CPR futile and undignified in advanced dementia
Lasting Power of Attorney (LPA) — Health & Welfare LPA appointed while capacity retained
Preferred place of death — most prefer home or care home, not hospital
Comfort care pathway — symptom management only; avoid burdensome investigations/interventions

End-of-Life Signs in Advanced Dementia

Loss of ability to swallow safely
Profound weight loss and cachexia
Recurrent chest infections
Non-ambulatory, bedbound
Minimal verbal communication
No recognition of family members

Comfort Care Priorities

Pain assessment — Abbey Pain Scale (non-verbal)
Symptom control: analgesia, anti-secretory medication, anxiolytics
Regular mouth care
Repositioning — pressure area care
Family presence and psychological support
Spiritual and religious needs — Imam/chaplain in GCC context

Safeguarding Vulnerable Adults

Dementia patients at high risk of abuse (financial, physical, emotional, sexual, neglect). Know local safeguarding procedures. Any concern must be escalated to safeguarding lead. Document objectively.

Carer Burden Assessment

Zarit Caregiver Burden Inventory

22-item self-report tool. Domains: personal strain, role strain. Scores 0–88.

Little/no burden<21

Mild–moderate burden21–40

Moderate–severe burden41–60

Severe burden>60

Also: Carer's Assessment of Managing Index (CAMI), Brief Assessment Schedule Depression Cards (BASDEC)

Signs of Carer Burnout to Assess

Physical health deterioration
Depression and anxiety in carer
Social isolation and loss of friendships
Financial strain from reduced work
Relationship breakdown with other family members
Sleep deprivation
Neglecting own health needs
Feelings of guilt, resentment, grief

Carer Health Is Patient Safety

A burned-out carer cannot provide safe care. Carer wellbeing assessment must be a routine nursing intervention, not an afterthought.

Community Support Resources

UK / International Context

Memory clinics — diagnosis, monitoring, medication management
Admiral Nurses (Dementia UK) — specialist community dementia nurses who support families
Alzheimer's Society — information, Dementia Connect helpline, peer support groups
Day centres — structured activities, respite for carers, social interaction
Cognitive Stimulation Therapy (CST) groups
Carers' support groups

GCC-Specific Resources

DHA Memory Assessment Clinics (Dubai)
SEHA Memory Clinics (Abu Dhabi/DOH)
Geriatric care services — SCFHS-accredited facilities
Home healthcare services
Social welfare support for disabled/elderly (UAE Federal)

Respite Care Options

Day care/respite centres — daytime care, several days per week
Short-stay residential care — planned breaks for carers
Home sitting services — trained volunteer or paid sitter
Overnight respite — residential placement for planned holidays
Emergency respite — crisis placements

GCC Cultural Note on Institutional Care

In GCC cultures, placing a family member in residential/institutional care is often strongly stigmatised — viewed as abandonment or failure of family duty. Nursing assessment must acknowledge this, provide non-judgemental support, offer community-based alternatives where possible, and help families reframe respite as enabling better home care.

Legal & Financial Planning

Power of Attorney (UK Framework)

Lasting Power of Attorney (LPA) — must be arranged while patient has capacity; two types: (1) Property & Financial Affairs; (2) Health & Welfare
Court of Protection — if capacity lost before LPA registered; court appoints a Deputy
Deputyship application — costly and slow; stresses importance of early planning

GCC Legal Context

UAE: Guardianship applications through courts for incapacitated adults
No direct equivalent of LPA — family guardianship is assumed culturally but legally complex
Financial planning: bank accounts, property, pensions — formal documentation needed

Financial Benefits (UK)

Attendance Allowance (over 65)
Personal Independence Payment (under 65)
Carer's Allowance for family carers
Council tax reduction
NHS Continuing Healthcare (fully funded care)

Grief & Anticipatory Loss

Families experience grief throughout the illness — "ambiguous loss" (person is physically present but psychologically absent). Acknowledge this with carers. Pre-bereavement counselling referral where available.

Dementia-Friendly Environment Design Principles

Lighting

High levels of natural light — reduce confusion
Consistent lighting — no harsh shadows or glare
Night lights for navigation
Avoid flickering lights
Light therapy units for circadian rhythm

Contrast & Colour

High colour contrast: toilet seats vs. surrounds
Contrast plate colours vs. tablecloth (improves eating)
Avoid busy patterns on floors (misperceived as objects)
Colour-coded areas/rooms
Matt surfaces — avoid reflective floors (perceived as water)

Orientation Aids

Large-face clocks and calendars in key rooms
Clear, simple signage with pictures (not only text)
Visible toilet signs / pictograms
Memory boards: name, family photos, daily schedule
Consistent room layout — avoid rearranging furniture

Carer Education Programmes & Self-Care

Structured Carer Education

STAR-C (Skills Training and Resourcefulness for Carers)
START (STrAtegies for RelaTives) — manualised intervention
Living Well with Dementia workshops
Online modules: Alzheimer's Society, Dementia UK
Topics: understanding dementia, communication skills, managing BPSD, safety, legal planning

Carer Self-Care Guidance

Maintain own social connections — avoid isolation
Regular GP health checks
Accept help — delegate tasks to other family members
Set boundaries — emotional and physical limits are valid
Access peer support groups
Mindfulness/relaxation techniques
Exercise — proven stress reduction
Acknowledge grief, sadness, and frustration as normal

GCC Dementia Epidemiology & Context

Rising Burden

GCC countries have some of the world's highest rates of Type 2 diabetes, hypertension, and obesity — all major vascular dementia risk factors
Rapidly ageing expatriate populations + native elderly population growth
Dementia prevalence in GCC projected to increase substantially by 2050
Limited public awareness — dementia often perceived as "normal ageing" (كبر السن), not a disease requiring investigation

Cultural Considerations

Family caregiver model — family (often women/daughters-in-law) provide care at home; institutional care carries social stigma
Language barriers — Arabic-language validated cognitive assessments remain limited; MMSE Arabic versions exist but have varying sensitivity
Disclosure of diagnosis — in some families, diagnosis may be withheld from patient (family protective approach); conflicts with Western informed consent models
Spiritual interpretation — dementia may be viewed through religious lens; engage respectfully

Ramadan & Medication Management

Donepezil (Aricept)

Normally taken at bedtime (reduces insomnia)
During Ramadan: take at Iftar (breaking fast at sunset) — maintains efficacy, avoids daytime fasting restriction
Monitor for GI symptoms if dietary patterns significantly change
Once-daily dosing favourable for Ramadan adherence

Memantine

Once-daily morning dosing standard
During Ramadan: may be taken at Suhoor (pre-dawn meal) to maintain schedule
Or switch to Iftar if Suhoor inconvenient — consistent timing most important
Ensure adequate hydration — memantine metabolised renally

General Ramadan Medication Principles

Muslim patients with dementia may insist on fasting even when medically inadvisable. Nursing responsibilities: assess cognitive capacity to make informed decision about fasting, involve family and religious authority (Sheikh) in discussions, ensure safety, document risk assessment and discussions. Rivastigmine patch — not affected by fasting (transdermal).

🔬 Dementia vs Delirium Differentiator Tool

Onset

Fluctuating course?

Attention impaired?

Consciousness altered?

Identifiable reversible cause?

Duration of symptoms

DHA / DOH / SCFHS Exam Preparation — High-Yield Questions

Q: A 74-year-old woman presents with progressive memory loss over 2 years. MRI shows medial temporal lobe atrophy. MMSE is 19/30. What is the most likely diagnosis and first-line treatment?

A: Alzheimer's disease (moderate stage, MMSE 10–19). First-line: cholinesterase inhibitor — donepezil, rivastigmine, or galantamine. Baseline ECG and HR before initiating.

Q: A patient with dementia develops well-formed visual hallucinations, fluctuating cognition, and tremor. What is the diagnosis, and what is the critical prescribing caution?

A: Lewy Body Dementia. Critical caution: AVOID antipsychotics — severe neuroleptic sensitivity causing NMS-like reaction, irreversible parkinsonism, and potentially fatal deterioration.

Q: How do you differentiate delirium from dementia at the bedside?

A: Key distinguishing features: Onset (delirium = acute hours–days; dementia = insidious months–years), Attention (markedly impaired in delirium = hallmark), Consciousness (altered in delirium; alert in dementia until late), Course (fluctuating in delirium), Reversibility (delirium reversible if cause treated). Use 4AT or CAM for delirium screening.

Q: Name 4 reversible causes of dementia that must be excluded in all new cases.

A: Hypothyroidism (TFTs), Vitamin B12 deficiency, Normal Pressure Hydrocephalus (CT: ventriculomegaly; triad: gait/incontinence/cognitive decline), Subdural haematoma. Also: neurosyphilis, depression (pseudodementia), medication toxicity.

Q: What are the 5 domains scored on the MMSE and the total possible score?

A: 30 points total. Domains: (1) Orientation to time & place (10 pts), (2) Registration (3 pts), (3) Attention & calculation/serial 7s (5 pts), (4) Recall (3 pts), (5) Language + visuospatial (9 pts).

Q: A patient on risperidone for BPSD develops a fever of 39.5°C, rigidity, and autonomic instability. What do you suspect and what is the immediate action?

A: Neuroleptic Malignant Syndrome (NMS). Immediate action: STOP antipsychotic immediately, emergency medical assessment, IV fluids, temperature management, ICU referral if severe, consider dantrolene/bromocriptine.

Q: What are the 4 criteria for the functional test of mental capacity under the Mental Capacity Act?

A: The patient must be able to: Understand the information → Retain it long enough to use it → Weigh up / use the information → Communicate their decision (verbally, written, or other means).

Q: In GCC practice, what specific cultural consideration affects cognitive testing in Arabic-speaking elderly patients?

A: Lack of validated Arabic-language cognitive assessments. Standard MMSE/MoCA were developed in English-speaking populations. Arabic adaptations exist but have limited validation data. Education level (including literacy) significantly affects scores. Cultural content (orientation questions, language tasks) may not be culturally equivalent. This is a recognised practice gap in GCC dementia care.
