12.1 Dementia and Alzheimer's Disease Care
Key Takeaways
- INACE is 85 questions in 90 minutes via SIU-Carbondale; Illinois requires 120 training hours including 12 hours of dementia/Alzheimer's care
- Dementia is a slow, irreversible syndrome; sudden new confusion suggests reversible delirium (often a UTI) and must be reported
- Alzheimer's is the most common dementia (60-80%); use one-step directions, validation, and redirection — never argue or quiz
- Manage wandering, sundowning, and agitation by finding the trigger; reduce stimulation, boost evening lighting, keep routines consistent
- Never restrain or force care during agitation — stop, stay calm, and try again later with a new approach
- Safety tools: wander-guard alarms, secured units, locked hazards, supervised meals, bed alarms, familiar objects
Why Dementia Care Dominates the Illinois CNA Exam
Caring for residents with dementia and Alzheimer's disease is tested heavily under the cognitive-care and psychosocial content of the Illinois Nurse Aide Competency Evaluation (INACE) — the 85-question, 90-minute written exam administered by Southern Illinois University Carbondale (SIU-C) for the Illinois Department of Public Health (IDPH). The INACE is pass/fail and the exact cut score is confidential, so you cannot "give back" weak dementia answers and pass on volume alone.
Illinois requires a 120-hour nurse-aide program (80 classroom + 40 clinical) — well above the federal OBRA (Omnibus Budget Reconciliation Act) minimum of 75 hours — and 12 of those hours must specifically cover dementia and Alzheimer's care. Any facility admitting residents with Alzheimer's or related dementias must give aides who did not get those 12 hours in school an additional 12 hours of in-house dementia training. Expect questions that assume you know this 12-hour rule exists.
Dementia Is a Syndrome, Not One Disease
Dementia is a group of symptoms — progressive loss of memory, reasoning, language, and the ability to perform activities of daily living (ADLs) — severe enough to interfere with independent living. It is not a normal part of aging. Distinguish it from delirium, a sudden, reversible confusion caused by infection (commonly a urinary tract infection), dehydration, medication, or pain. A trap question: a normally calm dementia resident becomes acutely more confused overnight — the correct action is to report a possible delirium/UTI to the nurse, not to assume "the dementia is just getting worse."
| Type | Hallmark feature | Course |
|---|---|---|
| Alzheimer's disease | 60-80% of cases; amyloid plaques and tau tangles | Slow, steady, irreversible; 4-20 yrs |
| Vascular dementia | Follows strokes / small-vessel disease | Often stepwise, abrupt drops |
| Lewy body dementia | Visual hallucinations, Parkinson-like stiffness | Fluctuating alertness day to day |
| Frontotemporal dementia | Personality / language change first | Younger onset (40-65) |
| Mixed dementia | Two or more types together | Variable |
Three Stages of Alzheimer's and What the CNA Does
- Early (mild): short-term memory loss, word-finding trouble, poor judgment, getting lost. CNA role: cue and remind, label drawers, supervise ADLs, watch safety. Promote independence — do for the resident only what they truly cannot do.
- Middle (moderate): worsening confusion, wandering, sundowning, incontinence, may not recognize family. CNA role: hands-on ADL help, structured routine, behavior management.
- Late (severe): total dependence, near-mute, bed-bound, dysphagia and weight loss. CNA role: total care, aspiration precautions, skin/pressure-injury prevention, comfort, family support.
Communication: The Tested Core
| Do | Avoid |
|---|---|
| Approach from the front, make eye contact, identify yourself | Surprising from behind |
| One idea per sentence: "Sit here, please" | Multi-step requests |
| Speak slowly; allow processing time | Rushing or finishing sentences |
| Use positive phrasing: "Let's walk this way" | "Don't go there" |
| Validate feelings: "You seem worried" | "Don't you remember? I just told you" |
| Redirect to a pleasant activity | Arguing, correcting, quizzing |
| Show the object (toothbrush) as you speak | Abstract verbal-only instructions |
A resident asking for a long-dead spouse is the classic validation vs. reality-orientation item: do not say "Your husband died years ago" (a catastrophic-reaction trigger). Acknowledge the feeling — "You miss him; tell me about him" — then redirect.
Behavioral Symptoms and CNA Response
| Behavior | Common trigger | First CNA action |
|---|---|---|
| Wandering | Restlessness, looking for the familiar, pain, boredom | Safe walking path, ID/alarm, redirect; never restrain |
| Sundowning | Late-day fatigue, low light, overstimulation | Boost lighting, calm the unit, reassure |
| Agitation / aggression | Unmet need, pain, overstimulation | Stop, stay calm, find the trigger, report |
| Repetitive questions | Memory loss, anxiety | Answer patiently each time; redirect |
| Refusal of care | Fear, not understanding | Back off, try later, change approach — don't force |
| Catastrophic reaction | Sensory/emotional overload | Reduce stimulation, lower your voice, give space |
Worked scenario: A middle-stage resident keeps trying to leave to "pick up the kids from school." Best response — walk with her, talk about the children, then guide her to a snack or activity (redirection + validation). Wrong responses — telling her the kids are grown, blocking the door, or restraining her.
Sundowning and Environmental Safety
Reduce sundowning with a consistent routine, brighter afternoon/evening lighting, less noise after dinner, daytime activity to promote night sleep, no caffeine after noon, and curtains closed before dark. Key safety tools: wander-guard bracelet or door alarm, secured unit to prevent elopement, hazards (chemicals, sharps, meds) locked away, supervised meals to prevent choking, bed/chair alarms, familiar photos and blankets, and good lighting to cut shadows that cause misperception.
Restraints, Dignity, and Resident Rights
Under OBRA and Illinois rules, residents have the right to be free from physical and chemical restraints used for staff convenience or discipline. A wander-guard alarm is a monitoring device, not a restraint; tying a confused resident into a chair to stop wandering is. The tested principle is that restraints are a last resort, used only on a provider's order for the resident's safety, and that distraction, exercise, toileting, and addressing pain come first. Forcing care, locking a resident in a room, or restraining for agitation are abuse and are always wrong answers.
Promoting Independence and Person-Centered Care
Even in late dementia, person-centered care maximizes whatever ability remains. Break tasks into one step at a time, offer limited choices ("Blue shirt or green shirt?" not "What do you want to wear?"), and let the resident do what they can — handing them the washcloth, guiding rather than doing. Honor lifelong routines: a resident who always showered at night should not be forced into a morning bath. Keep familiar items in place; a relocated photo or moved bed can trigger fear. Approaching care as collaboration, not as a task done to the resident, lowers resistance and is the answer the INACE rewards.
Quick Reference: Dementia Do's and Don'ts
- Do approach calmly from the front and identify yourself.
- Do validate the emotion, then redirect.
- Do report sudden confusion as possible delirium.
- Don't argue, quiz, or correct memory errors.
- Don't restrain or force care during agitation.
- Don't rush, raise your voice, or use baby talk ("elderspeak").
A resident with Alzheimer's asks you the same question for the fifth time in 10 minutes. What is the best response?
A normally calm dementia resident suddenly becomes much more confused and agitated over a single evening. What should the CNA do first?
A dementia resident becomes agitated and starts yelling when you try to help them get dressed. What should you do FIRST?
