Care of the Cognitively Impaired Resident
What you must understand
Distinguish the three Ds. Dementia is a slow, progressive decline in memory and thinking (Alzheimer's disease is the most common cause). Delirium is a sudden change in attention and awareness, often from infection, medication, or dehydration - a medical emergency that must be reported. Depression can mimic dementia but is treatable and should be reported.
In dementia, memory for recent events goes first, then language, judgment, and self-care. Behavior is communication: hitting during a bath may mean pain, fear, cold, or being rushed. Look for the trigger before you react. Communication works best with one short instruction at a time, simple words, a calm voice, eye contact, and plenty of time. Do not quiz the resident ("Do you remember me?") and do not argue about facts. In early dementia, gentle reorientation helps; in later stages, join their reality and redirect rather than correct.
Safety is central: wandering (use alarms, safe walking, and secure exits per policy), elopement risk, burns in the kitchen, swallowing problems, and poisoning. Keep routines predictable, reduce noise, put labels and pictures on doors, lay out clothing in order, and cue step by step. Sundowner's - increased confusion in late afternoon and evening - is eased by light, activity, and a calm bedtime routine. Distract or redirect during an outburst rather than restraining.
Traps the exam sets
- Arguing with a resident who insists it is 1972, or correcting every mistaken statement.
- Restraining a resident who wanders instead of providing safe activity and reporting the risk.
- Missing a sudden change in mental status - that is delirium, not "just their dementia."
Rule of thumb
Ask "what is this behavior telling me?" before you react, and use distraction instead of correction.
