Dementia doesn't follow a schedule. Neither does the fear, exhaustion, and heartbreak that comes with watching someone you love change. This handbook covers the four types of dementia and how they differ, the three stages and what each requires, sundowning and wandering, the language that calms and the language that wounds, and the moment professional help genuinely helps. Written for the family members doing the hardest work.
Dementia is not a single disease. It is a group of conditions, Alzheimer's, vascular dementia, Lewy body dementia, frontotemporal dementia, that progressively impair memory, thinking, and behaviour. Every person's experience is different.
What they all share: the person you love is still in there. They may not always recognise you. They may say things that hurt. They may not remember the conversation you had five minutes ago. But they can still feel love, comfort, frustration, and fear. Your presence matters, even when they cannot tell you it does.
This guide covers the practical challenges you will face and what you can do about each, whether you are providing care yourself or working with a professional caregiver.
The five most common types of dementia look different, progress differently, and call for different care. Knowing which one is in the room shapes every decision, including which medications help and which actively harm.
What families often notice. Memory loss is the earliest and most prominent sign. Word-finding difficulty, getting lost in familiar places, repeating questions. Personality changes appear later.
Why care is different. Routine and repetition are protective. A calm, predictable environment with the same caregiver helps. Sundowning is common and manageable with light, structure, and pacing.
What families often notice. Visual hallucinations (often vivid and non-threatening to the person), motor symptoms similar to Parkinson's, fluctuations in alertness from hour to hour, REM sleep behaviour disorder, sensitivity to certain medications.
Why care is different. Alertness can change dramatically through the day, so caregivers adapt in real-time. Fall risk is higher than in pure Alzheimer's. Some antipsychotics worsen symptoms severely, always check with the prescriber.
What families often notice. Step-wise decline after vascular events (strokes, TIAs). Slowed thinking, planning difficulty, balance issues, mood changes. Memory may be relatively preserved early.
Why care is different. Blood pressure discipline and second-stroke prevention matter as much as cognitive care. Mobility and safety supervision are central; mood support is often needed.
What families often notice. Personality and behaviour changes appear before memory loss. Impulsivity, poor judgment, loss of social awareness, inappropriate comments, sometimes language difficulty.
Why care is different. Caregivers need structured strategies to respond calmly to behaviour changes. Memory may seem intact, which is confusing for families. Safety planning around impulsivity is central.
What families often notice. Two or more dementia types present at once, most often Alzheimer's plus vascular. Symptoms blend, complicating diagnosis and treatment.
Why care is different. Care plans address whichever symptom set is dominant at the moment, and adapt as the picture shifts. A registered nurse care manager is especially helpful here.
Dementia is not a single state to plan around, it progresses through three broad stages, each with its own challenges and its own right level of support. The boundaries blur in practice, but knowing where you are tells you what to plan for next.
Often 2–4 years
What you may seeGoal: preserve normal life while gently closing safety gaps. Medication reminders, driving and cooking-safety conversations, discreet supervision, and family coaching on what may come next. A few hours a week of companion care is often the right starting dose.
Often 2–10 years (the longest stage)
What you may seeGoal: maintain safety, dignity, and quality of life. Consistent dementia-trained caregivers, sundowning routines, wandering prevention, personal-care assistance, and family respite. This is often when families bring in professional support, typically 4–8 hours daily, scaling up as needs change.
Often 1–2 years
What you may seeGoal: comfort and dignity at home. 24-hour or overnight awake care, safe transfers, mealtime support with swallowing precautions, skin protection, and coordination with hospice when appropriate. Many families add 24-hour care or hospice support in this stage.
As the sun goes down, confusion, anxiety, and agitation go up. Up to 66% of dementia patients experience sundowning. Your loved one may become restless, pace, argue, or try to leave the house, at exactly the time everyone is most tired.
Wandering can happen at any stage, day or night, often without obvious triggers. If not found within 24 hours, up to 50% of wanderers suffer serious injury or death. Home safety is the most important preventive step.
“Don't you remember?”
“Let me tell you about that.”
Asking someone with dementia if they remember causes frustration and shame. They cannot, that's the disease.
“You already asked me that.”
“Great question. Here's the answer.”
Repetition isn't a choice. Answer each time as if it's the first time. Your patience is their comfort.
“No, that's wrong.”
“I can see why you'd think that. Tell me more.”
Correcting doesn't help, it agitates. Enter their reality rather than dragging them into yours.
“You need to eat / You need to bathe.”
“This looks delicious. Let's eat together. / The warm water feels so nice today.”
Invitations work better than instructions. Join the activity rather than commanding it.
One of the highest-yield interventions in dementia care is also one of the least discussed: a thorough medication review. Several common drug classes worsen cognition, accelerate decline, or interact with dementia in ways an unaware prescriber may not catch. None of these should be stopped on your own, but every one deserves a conversation with the primary care doctor or neurologist.
Common examples: Benadryl (diphenhydramine), Tylenol PM, Advil PM, ZzzQuil, Bentyl, oxybutynin, hyoscyamine, many antihistamines and bladder-control medications
Block acetylcholine, the exact neurotransmitter dementia medications (Aricept, Exelon) try to preserve. Strong association with worsening confusion and accelerated cognitive decline. The American Geriatrics Society Beers Criteria flags these as 'potentially inappropriate' in older adults.
Common examples: Ativan, Xanax, Valium, Klonopin
Increase falls, worsen confusion, and create dependence quickly in older adults. The half-life is much longer in people over 70. Sometimes used for anxiety in early dementia, then become impossible to stop without medical supervision.
Common examples: Haldol, Risperdal, Zyprexa, Seroquel
Standard antipsychotics can cause severe and sometimes permanent worsening of Lewy body dementia symptoms, a 50% increase in confusion, rigidity, and falls. Quetiapine (Seroquel) is the safest of the class if one must be used; first-generation antipsychotics like Haldol can be dangerous.
Common examples: Ambien (zolpidem), Lunesta, Sonata, Restoril
Z-drugs and benzodiazepine sleep aids both increase fall risk overnight (when bathroom trips happen) and worsen morning confusion. Melatonin and behavioural sleep interventions are usually safer.
Common examples: MS Contin, OxyContin, fentanyl patches
Long-acting opioids cause persistent confusion in older adults with dementia. Short-acting alternatives at lower doses are usually safer where pain control is genuinely needed.
Common examples: Soma, Flexeril (cyclobenzaprine), Robaxin
Beers Criteria flags these as inappropriate for older adults. Cyclobenzaprine in particular is highly anticholinergic. Most have safer alternatives.
Bring the full medication list, every prescription, every over-the-counter, every supplement, to the next PCP or neurology visit and ask for a deprescribing review. Many Houston Methodist and UTHealth geriatric clinics now run dedicated polypharmacy clinics. We can help you prepare the list and the questions.
When dementia behaviour escalates, agitation, aggression, refusal of care, accusations, most families react instead of respond. The D.I.C.E. framework, developed at the University of Michigan and used widely in memory units, gives you a four-step intervention you can run in real time. We teach this to every caregiver we send into a dementia home.
Describe the behaviour out loud (to yourself, then on paper). When did it start? Where? Who else was present? What had just happened? What was your loved one doing 30 minutes before? Specifics matter, agitation at 4 p.m. on Saturdays after watching the evening news has a cause; 'agitation' as a label does not.
Investigate the most likely causes in this order: pain (UTI is the single most common cause of acute behaviour change), hunger or thirst, constipation, full bladder, fatigue, overstimulation, medication side effect or new medication, infection, environmental trigger (noise, temperature, unfamiliar visitor). Most acute behaviour change has a physical cause, not psychological.
Create a plan to address the most likely cause first. UTI screen at next PCP visit. Move the agitation-triggering activity to a calmer time of day. Reduce visitor count. Switch off the news. Adjust medication timing. The plan should be specific and try one thing at a time so you can tell what worked.
Evaluate after 5–7 days. Did the behaviour change? Get better? Get worse? If no change, return to step I and consider the next-most-likely cause. The discipline of writing down what you tried, and what happened, is the difference between an intervention plan and a hunch.
The D.I.C.E. framework is in the medical literature as effective as low-dose antipsychotic medication for managing agitation in dementia, with none of the side effects. We use it daily.
These are the places we refer Houston families to when they need something we don’t provide. Not a comprehensive directory, just the ones our care managers trust enough to send their own clients.
Premier diagnostic center for memory disorders in Houston. Comprehensive cognitive assessment, brain imaging, and care planning. Accepts most insurance. Usually a 4–6 week wait for new appointments, call early.
Strong for atypical presentations (FTD, Lewy body, posterior cortical atrophy). Research-active, so clinical trial enrollment is often available. Located in the Texas Medical Center.
Free 24/7 helpline (800-272-3900), care consultations, support groups (in-person and virtual), legal-financial planning workshops. The first call most newly-diagnosed families should make.
Houston-area faith-based community with respite and day programs for adults with cognitive disability, useful for some early-to-middle-stage families looking for structured daytime engagement.
Free counselling and education for family caregivers of older adults. Especially useful in the first months after diagnosis when families don’t yet know what they don’t know.
Independent geriatric care managers who can coordinate complex multi-specialist care. Useful when family decision-making is fragmented or geographically scattered. We work alongside several Houston-based ALCA members.
Formal driving evaluation when families are unsure whether a parent should still be on the road. Costs ~$400 and is more credible to the parent than the family raising the question themselves.
Free information, referral, and case-management services for older Texans. The Harris County AAA has STAR+PLUS Medicaid waiver navigators who can help income-qualifying families.
Activity of Daily Living. The six are bathing, dressing, transferring, toileting, eating, and continence. Most insurance triggers require help with 2 of 6.
Lack of insight into one's own deficits. In dementia, this is neurological, not denial. A person with anosognosia genuinely cannot perceive their cognitive changes.
Behavioural and Psychological Symptoms of Dementia. Includes agitation, aggression, paranoia, hallucinations, depression, apathy, wandering, and sleep disturbance.
A delusion that a familiar person has been replaced by an identical imposter. Occurs in some dementia types, especially Lewy body. Reassurance and redirection, not correction.
A 15- or 30-item screening tool for depression in older adults. Often used alongside cognitive screening because depression can mimic, or accompany, dementia.
Mini-Mental State Examination. A 30-point cognitive screening tool. Scores: 24–30 normal, 18–23 mild impairment, 0–17 moderate-severe.
Montreal Cognitive Assessment. A more sensitive 30-point test than MMSE, picks up earlier impairment. Standard in most modern memory clinics.
An approach that prioritises the person's preferences, history, and values over task completion. The opposite of 'institutional' or 'task-focused' care.
Sudden episodes of crying or laughing that don't match the person's actual mood. Common in vascular dementia and some Lewy body cases. Treatable.
Late-afternoon or evening increase in confusion, anxiety, or agitation. Affects up to two-thirds of dementia patients at some stage. Light, structure, and pacing usually reduce it.
A communication approach that joins the person's emotional reality rather than correcting their factual mistakes. Often described as 'meeting them where they are.'
Wandering happens at home; elopement is when the person leaves the home (or facility) without supervision. Up to 60% of dementia patients wander at some point.
There is no perfect moment. But these are the signs that professional support would improve life for your loved one, and for you.
Getting professional help is not giving up on the person in your care. It is making sure they receive the specialised, patient, consistent care that dementia requires, while preserving your relationship as a family member, not just a caregiver.
Andrew Harris, RN trained in the Neuro ICU at Houston Methodist. He understands the clinical reality of cognitive decline, not just the caregiving side.
Our caregivers receive dementia-specific training in sundowning management, redirection, communication, and safety. Not a credential, a daily practice.
Dementia crises don't wait for business hours. Care starts the same day you call, even Sundays. No contracts. We handle the LTCI claim.
If the person in your care requires supervision for safety (wandering, leaving the stove on, medication errors), if sundowning is disrupting sleep for the whole family, or if you as the caregiver are experiencing burnout, these are all indicators that professional support would improve quality of life for everyone. Most families wait too long; calling for guidance doesn't mean committing to care.
Our caregivers receive specialised training in memory care covering sundowning management, redirection techniques, communication strategies (the Positive Approach to Care), safety protocols, and behavioural support. Andrew Harris, RN trained in the Neuro ICU at Houston Methodist; he brings clinical neurological expertise to every dementia plan. Two of our three care managers are former Neuro ICU nurses.
Yes, this is one of the most common reasons families call us. A trained caregiver can maintain calming routines during late afternoon and evening, redirect anxiety, ensure safety during confusion, and give family members a chance to rest during what is often the most difficult time of day. We see sundowning improve within the first two weeks of consistent professional support.
Resistance is very common, especially in early-stage dementia. We don't introduce our caregivers as 'caregivers.' We introduce them as companions, someone to help around the house, share a meal, take a walk. The relationship builds naturally. Many families tell us their parent looks forward to visits within the first week. The care manager coaches families on the language and timing of the introduction.
Diagnosis comes from a neurologist or geriatric specialist, usually a combination of cognitive testing, brain imaging, and observation over time. Some types (like Lewy body) are often misdiagnosed as Alzheimer's at first. The type matters: medication that helps Alzheimer's can dramatically worsen Lewy body, for example. If you don't have a clear diagnosis, a referral to UTHealth McGovern Medical School or Houston Methodist Neurology is a good starting point.
Usually, yes, with the right support. Most families can keep a parent home through middle-stage dementia with 4–12 hours of professional care daily, plus home safety modifications (locks, GPS, kitchen safety). Late-stage dementia often requires 24-hour care to keep someone home safely. The question shifts from 'can we?' to 'should we?' when wandering becomes uncontrollable, when sleep is impossible, or when the family caregiver's own health is suffering.
Polypharmacy is common, and often part of the problem. Some medications worsen confusion (anticholinergics, benzodiazepines, certain sleep aids). Our care managers review the full medication list during the assessment and flag concerns to the prescriber. We also handle daily medication reminders and document missed doses, which is what most caregivers don't do but should.
Yes. Both require different approaches than standard Alzheimer's care. Lewy body needs medication-safety awareness and fluctuation-aware caregivers. FTD needs structured behavioural strategies because the person's memory may be intact while their judgment isn't. Our Neuro ICU-trained care managers build plans accordingly.
Yes. Most LTC policies cover dementia care once the cognitive impairment trigger is met, which usually requires a formal cognitive assessment (Mini-Mental, MoCA, or BIMS) below the policy's threshold. We perform the assessment, document the findings in the carrier's preferred language, and bill the carrier directly via Assignment of Benefits.
Houston-area dementia home care typically runs $35–$45/hour for personal care, $400–$700/day for 24-hour rotations, and $300–$450/shift for awake overnight coverage. The free in-home Care Manager visit gives you an itemised written quote based on your specific situation. Long-term care insurance, VA Aid & Attendance, and some Medicare Advantage plans often cover most or all of the cost.
No commitment. No pressure. Just a clinical perspective on what would actually help your family.
