9.1 Dementia & Alzheimer's Care
Key Takeaways
- Dementia is a group of symptoms (memory, judgment, language, behavior loss), not normal aging — Alzheimer's is the most common cause.
- Florida's Prometric written test draws ~14% from Specialized Resident Care, where dementia care is a high-frequency topic.
- Use validation (acknowledge the feeling behind the words) for moderate-to-severe dementia; reality orientation suits early or delirium cases, not entrenched delusions.
- Maintain a consistent routine and a familiar caregiver; over-stimulation, change, and clutter increase agitation.
- Sudden new confusion in a usually alert resident is a change in condition (possible delirium) and must be reported to the nurse immediately.
Why Dementia Care Is Tested
The Florida CNA written test (60 questions, 70% to pass) pulls roughly 14% of items from Specialized Resident Care, and dementia is the heaviest sub-topic in that domain. Florida's large elderly population means a working CNA will care for residents with cognitive impairment on almost every shift, so Prometric items focus on practical, safe responses rather than medical theory.
Dementia is a group of symptoms — progressive loss of memory, judgment, language, reasoning, and behavior control — severe enough to disrupt daily life. It is not a normal part of aging. Alzheimer's disease is the most common cause; vascular dementia (from strokes) typically progresses in sudden step-downs. The CNA does not diagnose the type — the CNA recognizes behaviors, keeps the resident safe, and reports changes.
General Stages and What the CNA Sees
| Stage | What You Observe | CNA Focus |
|---|---|---|
| Early (mild) | Recent-memory lapses, repeating questions, misplacing items, still mostly independent | Cue and remind; protect dignity; encourage routine |
| Middle (moderate) | Disorientation, wandering, sundowning, needing help with ADLs, behavioral outbursts | Simplify tasks; supervise closely; redirect; ensure safety |
| Late (severe) | Minimal speech, total ADL dependence, swallowing and mobility loss, incontinence | Comfort, skin and mouth care, aspiration precautions, gentle touch |
Common Behaviors and Safe Responses
Difficult behavior is communication of an unmet need — pain, hunger, fear, a full bladder, noise, fatigue, or infection. The exam reward answer almost always looks for the cause and protects safety rather than scolding or arguing.
- Wandering / elopement: provide supervised safe walking paths, ensure the ID/registry-style identification band is on, alert the nurse if a resident is missing. Do not lock a resident in a room — that is an unlawful restraint under Florida resident-rights rules.
- Sundowning: increased confusion and agitation in late afternoon/evening. Increase lighting before dusk, reduce noise, keep the evening routine calm and predictable.
- Catastrophic reaction (sudden overwhelm): lower stimulation, stay calm, do not crowd the resident, give space and time, report.
- Repetitive questions: answer simply and consistently; do not say "I already told you."
- Hoarding / rummaging: provide a safe "rummage" drawer; do not shame the resident.
Environmental Safety Checklist
- Good, even lighting; reduce shadows and glare that trigger misperception.
- Remove clutter and trip hazards; non-slip flooring.
- Lock medications, chemicals, sharps, and hot-water access.
- Supervise eating; cut food per the care plan to prevent choking.
- Keep frequently used items visible and labeled; keep the layout consistent.
Validation vs. Reality Orientation
This distinction is a frequent Prometric item. Choosing the wrong approach can increase distress.
| Approach | What It Is | Best Used When |
|---|---|---|
| Reality orientation | Gently restating the true day, place, time, and names | Early dementia, delirium, or brief confusion where the resident can be reoriented without distress |
| Validation | Acknowledging the feeling behind the statement rather than correcting the facts | Moderate-to-severe dementia, fixed delusions, or when correcting the facts upsets the resident |
Example: a resident says, "I have to get home to feed my babies." Reality orientation ("Your children are grown adults, this is your home now") often escalates fear. Validation plus redirection works better: "It sounds like you really love your family. Let's have some lunch and you can tell me about them." You acknowledge the emotion, do not lie elaborately, and gently redirect to a safe activity.
Never argue with a delusion or hallucination, and never play along by fabricating detailed false stories. Acknowledge the feeling, reassure safety, redirect, and report new or worsening symptoms.
Reportable Right Away
A usually alert resident who becomes suddenly confused, drowsy, or agitated may have delirium from infection (especially UTI in older adults), dehydration, low oxygen, pain, or a medication effect. This is an acute change of condition — report to the nurse immediately. Do not assume it is "just the dementia getting worse."
A resident with moderate Alzheimer's becomes tearful, saying she must go pick up her young children from school. What is the best CNA response?
A resident with dementia who is normally calm and oriented to staff suddenly becomes very confused and agitated during an afternoon shift. What should the CNA do first?
