Caring for Patients with Dementia
Dementia is a progressive neurodegenerative syndrome that affects memory, thinking, behaviour, and daily function.
Caring for patients with dementia requires a holistic, person-centred approach, balancing medical treatment with psychological, social, and environmental support.
📊 Types of Dementia
- 🧩 Alzheimer’s disease – most common; memory-led decline, language impairment.
- 🩸 Vascular dementia – stepwise decline after strokes, executive dysfunction prominent.
- 👁️ Dementia with Lewy Bodies (DLB) – hallucinations, Parkinsonism, fluctuating cognition.
- 🗣️ Frontotemporal dementia – behavioural or language variant; often younger onset.
- 🔄 Mixed dementia – common in elderly; overlap of Alzheimer’s and vascular.
🔍 Core Principles of Dementia Care
- 👥 Person-centred care: Focus on the individual’s history, personality, and preferences.
- 📚 Education: Involve carers/families, explain disease trajectory.
- 🛡️ Safety: Falls prevention, medication review, home/environmental adaptations.
- 💊 Medication: Cholinesterase inhibitors (donepezil, rivastigmine, galantamine) or memantine in Alzheimer’s/Lewy body types if indicated.
- 🎯 Goals of care: Maintain independence, dignity, quality of life rather than cure.
🗣️ Communication Strategies
- Speak slowly, clearly, using short sentences.
- Maintain eye contact and use calm tone.
- Allow extra time for responses; avoid rushing.
- Use visual prompts, gestures, and written reminders.
- Involve family/caregivers who know the patient best.
🛠️ Managing Behavioural and Psychological Symptoms of Dementia (BPSD)
- 😟 Agitation & aggression: Identify triggers (pain, environment, infection). Use reassurance and distraction before drugs.
- 🛏️ Sleep disturbance: Optimise sleep hygiene, avoid caffeine, encourage daytime activity.
- 👻 Hallucinations (DLB/Parkinson’s): Often benign; only treat if distressing. Avoid antipsychotics if possible.
- 💊 Medications: Antipsychotics only if risk/severe distress (haloperidol contraindicated in Lewy body dementia; quetiapine preferred).
Non-Pharmacological (First-line)
- 💬 Reassurance, reorientation, validation therapy.
- 🧑🤝🧑 Involve family/carers in care routines.
- 🎶 Music therapy, pet therapy, reminiscence therapy.
- 🌅 Optimise environment: calm, well-lit, minimise noise.
- 👓 Sensory aids: glasses/hearing aids to reduce confusion.
- 🛏️ Sleep hygiene: regular routine, avoid caffeine, day-time activity.
Pharmacological (if severe distress or risk)
- Lorazepam 0.5-1 mg PO or IM (not IV) can be useful
- 💊 Antipsychotics:
- Haloperidol 0.5–1 mg (avoid in Lewy body/Parkinson’s).
- Quetiapine or risperidone (short-term, lowest dose, regular review).
- 😔 Antidepressants: SSRIs (e.g. sertraline, citalopram) if depression prominent.
- 😴 Sleep disturbance: Melatonin or trazodone preferred; avoid benzodiazepines unless short-term for crisis.
- ⚠️ Cautions: Antipsychotics ↑ risk of stroke and mortality in dementia - use only if severe risk/distress, review at 6–12 weeks.
Teaching pearl: Always look for underlying causes of behaviour change - pain, constipation, infection, delirium - before assuming it is “just dementia”.
🏡 Community & Social Support
- 👩⚕️ Memory clinics for diagnosis, support, and follow-up.
- 🏠 Social care input for home adaptations, carers, respite services.
- 🧾 Attendance allowance, carer’s allowance, lasting power of attorney (LPA).
- 🧑🤝🧑 Dementia charities (Alzheimer’s Society, Age UK) for patient/family support.
⚖️ Safeguarding & Legal Framework
- 🧠 Mental Capacity Act 2005: Capacity is decision-specific; may fluctuate.
- 📜 Advance Care Planning: Encourage early discussions about wishes (ACP, ADRT, DNACPR).
- 🛡️ Safeguarding: Dementia increases risk of neglect, abuse, financial exploitation.
- 🚗 Driving: Mandatory DVLA notification for dementia diagnosis.
🌅 End-of-Life Care in Dementia
- Focus on comfort, dignity, and symptom control.
- Anticipatory prescribing for pain, agitation, secretions, nausea.
- Discuss preferred place of care (home, hospice, care home).
- Support family/carers through bereavement process.
📝 OSCE / Exam Pearls
- Demonstrate empathy and patience when communicating with a “confused patient”.
- Always involve collateral history from carers/family.
- Differentiate delirium vs dementia vs depression in older adults.
- Mention cholinesterase inhibitors and memantine as part of medical treatment.
- State non-drug measures first when asked about behaviour management.
🎯 Key Takeaway
Caring for patients with dementia means much more than prescribing medication.
It requires holistic, person-centred care, with emphasis on communication, safety, dignity, and supporting carers.
Always consider reversible causes for behaviour change, and plan early for advance care and end-of-life needs. 🌟
