Care of Clients with Cognitive Impairment and Behavioral Needs
What this domain covers
Cognitive impairment includes dementia (Alzheimer's disease, vascular, Lewy body), delirium, traumatic brain injury, and mental illness. Dementia is usually gradual and progressive, affecting memory, judgment, language, and self-care. Delirium is sudden, fluctuating confusion with a medical cause - a medical emergency you report, not a normal part of aging.
Behavior is communication. Look for a cause: pain, hunger, thirst, constipation, full bladder, fatigue, noise, fear, or an unfamiliar caregiver. Respond to the feeling, not just the words. Use short sentences, one idea at a time, a calm voice, eye contact, familiar routines, and redirection. Validation - accepting the client's reality instead of arguing - reduces distress.
Safety comes first: wandering, burns, medication mix-ups, driving, and financial exploitation are real risks. Use identification, door alarms per the care plan, and supervision. Sundowning (late-day agitation) may ease with daylight, activity, and a calm routine. Never restrain a client; restraints increase injury and are not an aide's decision.
Support families, who often grieve the person they knew, and protect dignity during every task. Sudden worsening, new aggression, hallucinations, or refusal to eat must be reported.
Traps
Arguing that a deceased spouse is dead, correcting every mistaken statement, physically restraining an agitated client, assuming sudden confusion is dementia, and ignoring pain as a trigger.
Rule of thumb
Connect before you correct: join the client's reality, calm the feeling, then redirect to a safe activity.
