Caring for Clients with Dementia
Key Points
- Dementia is progressive cognitive decline that impairs memory, judgment, and daily functioning.
- Person-centered strategies prioritize safety, validation, routine, and unmet-need assessment behind behaviors.
- Effective care reduces agitation, wandering-related risk, and caregiver distress while preserving dignity.
Pathophysiology
Dementia reflects progressive neurodegenerative or vascular brain changes that disrupt memory, executive function, language, and behavior regulation. Common etiologies include Alzheimer disease, vascular dementia, Lewy body dementia, and frontotemporal dementia.
As cognition declines through early, moderate, and advanced stages, communication and self-care capacity decrease while supervision needs increase. Behavioral symptoms often signal unmet needs (pain, hunger, fear, toileting, overstimulation) rather than intentional resistance.
Classification
- Early stage: Subtle memory/executive decline with growing support needs.
- Moderate stage: Increased wandering, repetitive behaviors, hallucinations/delusions, and ADL assistance requirements.
- Advanced stage: Severe dependence, communication/swallow decline, incontinence, and high safety risk.
Nursing Assessment
NCLEX Focus
Priority questions ask which behavior signals immediate safety risk and which de-escalation approach should be tried first.
- Assess baseline cognition, communication ability, and behavior triggers.
- Observe for unmet-needs cues: pain, infection, constipation, hunger/thirst, fatigue, and sensory overload.
- Assess wandering/elopement risk, sundowning pattern, and aggression triggers.
- Report abrupt changes, especially sudden confusion, new hallucination distress, or unsafe behaviors.
Nursing Interventions
- Use validation therapy: acknowledge the person’s lived reality and emotional concern before redirection.
- Keep routines predictable and communication simple with one-step choices and extra processing time.
- Reduce environmental overstimulation (noise, clutter, shadows) and use calming activities.
- Provide supervised mobility, safe wandering alternatives, and tracking safeguards when ordered.
Elopement and Aggression Risk
Unrecognized triggers and delayed intervention can escalate to injury risk for both client and caregivers.
Pharmacology
| Drug Class | Examples | Key Nursing Considerations |
|---|---|---|
| cholinesterase-inhibitors | Dementia-symptom management context | Monitor daily-function trend and report decline despite treatment plan. |
| psychotropic-medications | Behavioral-symptom management context | Observe sedation/fall risk and escalate adverse effects promptly. |
Clinical Judgment Application
Clinical Scenario
A resident with moderate dementia becomes agitated at dusk, repeats requests to “go home,” and attempts to exit the unit.
Recognize Cues: Sundowning pattern, perseveration, and wandering risk. Analyze Cues: Distress likely reflects fear/disorientation, not intentional defiance. Prioritize Hypotheses: Immediate priority is safety with emotional de-escalation. Generate Solutions: Validate feelings, reduce environmental triggers, provide calming task, and increase supervision. Take Action: Implement routine-based redirection and notify team of behavior trend. Evaluate Outcomes: Agitation decreases and unsafe exit behavior is prevented.
