7.2 Dementia, Alzheimer's, and Behavior Responses
Key Takeaways
- Dementia is a long-term decline in memory, thinking, judgment, communication, or function; Alzheimer's disease is one common cause.
- Behavior often communicates an unmet need such as pain, fear, hunger, toileting need, boredom, overstimulation, or confusion.
- Safe dementia care uses routine, simple cues, validation, redirection, calm body language, and a low-stimulation environment.
- A CNA reports sudden changes, unsafe wandering, new aggression, swallowing problems, falls, pain cues, or behavior that does not match the resident's usual pattern.
Dementia Care Looks for the Need Behind the Behavior
Dementia is a general term for a decline in memory, thinking, communication, judgment, and function that interferes with daily life. Alzheimer's disease is a common cause of dementia, but not the only one. Some residents have vascular dementia, Lewy body dementia, Parkinson disease dementia, frontotemporal dementia, or mixed causes. The nurse aide does not diagnose the type. The aide follows the care plan and observes how the condition affects daily care.
Dementia is usually gradual. A resident may forget recent events, repeat questions, misplace items, lose track of time, have trouble finding words, resist bathing, wander, or become more upset in the evening. Memory loss is only one part. Judgment, safety awareness, swallowing, toileting, sleep, and emotional control may also change. A resident may still have strengths, preferences, humor, faith, memories, and skills that should be respected.
Behavior Detective Aid
| Behavior | Possible need or trigger | CNA response within role |
|---|---|---|
| Repeated call light | Fear, pain, toileting need, loneliness, confusion | Check comfort, answer calmly, report pattern |
| Wandering | Need to move, searching, boredom, pain, restroom need | Walk safely if allowed, redirect, protect exits per policy |
| Refusing bath | Cold room, embarrassment, pain, fear, past trauma | Offer choices, explain one step, adjust privacy and warmth |
| Yelling | Overstimulation, hunger, pain, unmet need | Lower noise, speak calmly, check basic needs |
| Accusing others | Misplaced item, fear, memory loss | Do not argue; help look and reassure |
| Restlessness at dusk | Fatigue, shadows, routine change, sundowning | Provide calm routine, light, toileting, and report |
The first rule is not to argue with the disease. If a resident says they must go home to pick up children, telling them their children are adults may increase distress. A better response is to acknowledge the feeling and redirect to safety. The aide might say that the children are safe and then invite the resident to walk to the dining room or fold towels. The goal is comfort and safety, not proving the resident wrong.
Use simple communication. Approach from the front, identify yourself, use the resident's preferred name, and explain one step at a time. Instead of asking whether the resident wants to get ready for breakfast, choose a concrete cue such as it is time to wash hands before breakfast. Offer two choices when possible: blue shirt or green shirt, wash face first or brush teeth first. Too much explanation can overwhelm.
Routine reduces fear. Many residents with dementia do better when care happens in the same order, with familiar objects and consistent staff approaches. A bath may be easier if the room is warm, supplies are ready, the resident is covered as much as possible, and the aide explains each step before touching. Rushing usually increases resistance. If care is not urgent and the resident is escalating, step back, allow a pause, and try again according to facility policy.
Behavior may be pain. A resident who cannot explain pain may grimace, guard a body part, strike out during care, refuse to move, moan, stop eating, or become restless. The aide reports pain cues to the nurse and documents objective observations if assigned. Do not assume aggression is just dementia. New or worsening behavior can signal infection, constipation, dehydration, medication effects, injury, sleep loss, grief, or delirium.
Wandering requires safety and dignity. Many residents walk because they need movement, are searching for something, or are trying to meet a goal from their past. If the care plan allows walking, the aide can walk with the resident, offer a familiar activity, guide toward a safe area, or redirect with food, music, folding, sorting, or conversation. The aide follows facility policy for alarms, secured areas, and elopement risk. Never restrain a resident or block them with force unless immediate safety policy requires emergency help.
Dementia can affect eating and drinking. A resident may forget to start, become distracted, pocket food, cough, or fail to recognize utensils. The aide follows the diet order and feeding instructions, offers cues, keeps the table calm, checks for dentures and glasses, and reports choking, coughing, pocketing, poor intake, or swallowing changes.
Personal dignity remains central. Do not use baby talk, laugh at mistakes, quiz memory, or talk about the resident as if they are absent. Preserve privacy during incontinence care and bathing. A resident with dementia may not remember the interaction, but their emotional response can last.
When to Report Quickly
Report sudden confusion, new agitation, new aggression, falls, head injury, fever signs, new incontinence, pain cues, refusal of fluids, choking, unsafe wandering, exit-seeking, hallucinations that frighten the resident, or any rapid change from usual behavior. Sudden change is not normal dementia progression until the nurse evaluates it.
A resident with Alzheimer's disease keeps saying she must leave to pick up her young children from school. She is standing near the exit and becoming tearful. What should the CNA do?
A resident with dementia begins striking at staff during dressing, which is unusual for him. He grimaces when his right arm is moved. What is the best action?
At supper, a resident with dementia stares at the plate and does not begin eating. The diet is correct and the resident is awake. Which CNA action is most appropriate?
