Dementia and Psychological Impairments

Dementia and Psychological Impairments

Cognitive and mental-health changes are central to Domain V on the Delaware Prometric CNA exam and to daily life in long-term care. Delaware underscores this priority at renewal: CNAs must complete 24 hours of continuing education every 24 months, including at least 6 hours related to dementia and 2 hours on abuse prevention, plus paid nursing-related work requirements. That policy exists because many residents live with Alzheimer’s disease and other dementias, and because poor communication can become neglect or abuse.

Your job is not to diagnose psychiatric disorders. You observe behavior, use therapeutic techniques from training, keep people safe, and report changes. Understanding common conditions helps you choose the right approach under stress.

Confusion: Not One Single Disease

Confusion means the person has difficulty thinking clearly—disorientation to time/place/person, poor attention, or disordered thoughts. Causes range from dementia to infection, medications, dehydration, hypoxia, pain, and sensory overload. Always treat new or sudden confusion as potentially medical until the nurse evaluates it.

Dementia vs delirium vs depression (high-yield comparison)

Delirium is a medical emergency signal at the CNA level: report sudden agitation, new hallucinations, extreme sleepiness, or acute confusion the same way you would report chest pain—now. Common triggers in elders include UTI, pneumonia, medication effects, dehydration, and post-op states.

Alzheimer’s Disease and Related Dementias

Alzheimer’s disease is the most common dementia. Progressive stages move from mild forgetfulness to severe dependence. Other dementias (vascular, Lewy body, frontotemporal) differ in details, but CNA communication principles overlap.

Communication that works

• Approach from the front; make eye contact if culturally appropriate; call the person by preferred name
• Use a calm, low voice and short simple sentences—one idea at a time
• Allow time to process; repeat with the same words before rephrasing
• Offer limited choices (“blue shirt or red shirt?”) rather than open-ended overwhelm
• Use gentle guidance and visual cues (show the toothbrush while saying “Let’s brush teeth”)
• Break tasks into steps; praise efforts
• Watch nonverbal signs of pain or fear when words fail

Validation—not endless argument

Residents may insist a deceased spouse is coming to dinner or that they must “go to work.” Do not argue or quiz them with “Don’t you remember he died?” That increases shame and agitation. Validation accepts the emotion underneath (“You miss him—tell me about him”) and then redirects to a safe activity. Therapeutic fibbing policies vary by facility; never invent harmful lies, but do not crusade to force painful reality every minute if the care plan supports gentle redirection.

Catastrophic reactions (sudden crying, striking out) often mean the person is overstimulated, rushed, in pain, or confused by too many steps. Stop the task, reduce noise, ensure safety, and try later with a simpler approach. Report triggers so the care plan can adapt.

Wandering and Exit-Seeking

Wandering may meet a need: exercise, looking for a bathroom, searching for home, or boredom. Risks include elopement, weather exposure, and traffic injury.

CNA safety actions:

• Know which residents are elopement risks; check alarms and locked units per policy
• Respond to door alarms immediately; never prop secured doors open
• Redirect calmly; walk with the person; offer toileting, snack, or purposeful activity
• Ensure identification bracelets/photos per facility system
• Report new exit-seeking, especially after room changes or sundowning patterns
• Restraints are not the first answer—least restrictive measures and nursing orders apply (Domain II safety links here)

Anxiety, Depression, Phobias, and Addiction Concepts

Anxiety

Anxiety shows as worry, restlessness, rapid speech, repetitive questions, or physical tension. CNA responses: stay calm, reduce noise, explain procedures before touch, allow extra time, and report panic-level episodes or new severe anxiety. Do not say “calm down” as an order; offer presence and simple breathing cues if trained and welcomed.

Depression

Depression is common in long-term care and is not normal aging. Signs: persistent sadness, loss of interest, sleep/appetite change, statements of worthlessness, social withdrawal, poor hygiene refusal. Report suicidal talk immediately and stay with the person while getting the nurse—do not leave a suicidal resident alone to “finish rounds first.” Encourage participation without forcing; small successes matter.

Phobias and fears

Specific fears (needles, baths, dogs, closed doors) may be long-standing. Honor reasonable adaptations on the care plan; never ridicule. Gradual, patient approaches work better than surprise.

Addiction and substance-related issues (CNA level)

Some residents have histories of alcohol or drug dependence; others misuse prescribed opioids or hide alcohol. CNAs may observe smell of alcohol, sudden mood change after visitors, missing controlled items, or withdrawal signs (tremor, agitation, sweating). Report observations factually to the nurse. Do not confiscate substances as a lone vigilante action outside policy; do not shame the resident. Safety, honesty in reporting, and nursing assessment come first. Understand that addiction is a medical-behavioral condition—stigma blocks care.

Defense Mechanisms and Difficult Behaviors (Practical View)

Residents (and families) may deny illness, project anger onto staff, or regress under stress. Take anger seriously as possible pain, fear, or unmet need—not only as a “behavior problem.” Use the same therapeutic tools taught in Domain I communication chapters: active listening, set kind limits on hitting/spitting, protect yourself and others, and get help early rather than struggling alone.

Never use demeaning nicknames, threaten “shots,” or withhold food as punishment. Those actions can constitute abuse and jeopardize Delaware registry status.

Age-Related Psychosocial Needs

Even without dementia, aging brings role loss, bereavement, and dependency. Support generativity and dignity: conversation about life history, cultural practices, spiritual routines, and meaningful choice. Confusion from sensory loss can mimic dementia—ensure glasses and hearing aids are used before labeling someone “noncompliant.”

Sundowning and Environmental Design

Many people with dementia worsen in late afternoon/evening (sundowning): pacing, shadow misperception, irritability. Reduce caffeine if ordered, increase daytime light and activity as appropriate, keep a consistent bedtime routine, limit chaotic TV violence, and ensure toileting and pain needs are met. Report patterns so staffing and activities can adjust.

Exam and Delaware Practice Focus

Prometric items reward the aide who:

• Reports sudden mental status change immediately (delirium pathway)
• Uses simple, calm, validating communication—not argument
• Protects wanderers with supervision and redirection
• Treats psychological symptoms with respect and factual reporting
• Understands that dementia care skill is a Delaware CE expectation, not optional soft skill

If two answers both sound kind, choose the one that preserves safety, dignity, and truthfulness in reporting without power struggles. That is specialized cognitive care for the Delaware CNA.
