Comprehensive Guide

Behavioral symptoms are among the most challenging and emotionally exhausting aspects of dementia care. Research published in the Journal of the American Medical Association estimates that up to 97 percent of individuals with dementia will experience at least one clinically significant behavioral or psychological symptom over the course of their illness. These symptoms — which range from agitation and aggression to hallucinations, wandering, depression, and resistance to care — are not simply inconveniences. They are the leading cause of caregiver burnout, the primary reason families seek institutional placement, and a significant contributor to reduced quality of life for both the person with dementia and everyone who supports them. This guide exists because managing behavioral symptoms effectively requires more than patience. It requires understanding.

Every behavior has a cause, even when that cause is not immediately apparent. A person who strikes out during bathing may be frightened by water temperature they cannot articulate. A person who wanders at dusk may be responding to a decades-old routine of picking up children from school. A person who refuses food may be experiencing mouth pain they can no longer describe. When caregivers learn to decode the meaning behind behaviors rather than simply reacting to them, the entire dynamic of care changes. Distress decreases.

Interventions become more targeted. And the person with dementia retains more dignity throughout the process. This pillar guide is designed to be the single most comprehensive resource on this site for understanding, preventing, and responding to the full spectrum of behavioral symptoms in dementia. Each section addresses a specific category of behavior, explains the neurological and environmental factors that drive it, and provides concrete, evidence-based strategies that caregivers can apply immediately. Where relevant, we link to more detailed articles on this site that explore specific subtopics in greater depth. Whether you are a family caregiver navigating these challenges for the first time, a professional working in memory care, or a clinician seeking a practical reference to share with families, this guide offers a structured framework for approaching behavioral symptoms with competence and compassion.

The strategies outlined here draw from current geriatric psychiatry guidelines, occupational therapy research, and the lived experiences of caregiving communities worldwide.

What This Guide Covers

Understanding Why Behavioral Changes Happen

Behavioral changes in dementia are not random. They are the direct and indirect consequences of progressive neurological damage interacting with a person’s environment, physical health, emotional state, and lifelong personality. Understanding this foundational principle is the single most important shift a caregiver can make, because it moves the response from “How do I stop this behavior?” to “What is this behavior telling me?” The brain changes in dementia are structural and functional. In Alzheimer’s disease, the hippocampus and frontal lobes deteriorate early, impairing memory, judgment, impulse control, and the ability to sequence tasks. In frontotemporal dementia, damage to the frontal and temporal lobes can produce dramatic personality changes, disinhibition, and compulsive behaviors even before significant memory loss appears. In Lewy body dementia, fluctuations in alertness and visual processing circuits produce vivid hallucinations and paranoia that feel entirely real to the person experiencing them. For a detailed exploration of this specific mechanism, see Why Lewy Body Dementia Can Lead to Severe Hallucinations and Aggression.

Each type of dementia carries its own behavioral signature, and recognizing which brain regions are affected helps caregivers anticipate rather than merely react. Beyond neurological damage, behavioral symptoms are frequently triggered or amplified by unmet needs the person can no longer express verbally. Pain is one of the most common and most overlooked triggers. A 2011 study in the British Medical Journal found that systematic pain treatment in nursing home residents with dementia reduced agitation by 17 percent compared to controls. Constipation, urinary tract infections, dental problems, hunger, thirst, fatigue, overstimulation, understimulation, loneliness, and fear are all common drivers of behavioral change. When a person with dementia suddenly becomes more agitated or withdrawn, the first question should always be medical: Is something physically wrong? Environmental factors are equally powerful. Loud, chaotic environments increase agitation.

Unfamiliar settings provoke anxiety. Changes in routine destabilize people who rely on predictability to compensate for memory loss. Even well-intentioned interventions — a new caregiver, a room rearrangement, a schedule change — can provoke behavioral responses that seem disproportionate until you consider how disorienting any change becomes when you cannot form new memories to adapt. Finally, the person’s lifelong temperament and history matter. Someone who was anxious before dementia will likely become more anxious. Someone who valued independence will resist help with greater intensity. Someone with a history of trauma may react to personal care in ways that reflect those earlier experiences.

Effective behavioral management always begins with knowing the person — not just the disease.

Understanding Why Behavioral Changes Happen

Agitation and Aggression: Triggers and De-Escalation

Agitation and aggression are among the most distressing behavioral symptoms for caregivers. Studies suggest that between 40 and 60 percent of people with dementia will exhibit significant agitation at some point during the disease, with verbal aggression being more common than physical aggression. These behaviors can include yelling, cursing, hitting, kicking, throwing objects, and resisting care. While alarming, they are almost always expressions of distress rather than deliberate hostility. The most common triggers for agitation include pain, overstimulation, feeling rushed or controlled, fear, confusion about what is happening, and perceived threats. Hallucinations and delusions can also drive aggressive responses when the person believes they are in danger. For an in-depth discussion of how perceptual disturbances contribute to violent behavior, see How Delusions and Hallucinations Influence Violent Behavior in Dementia. Caregivers themselves can inadvertently trigger agitation through tone of voice, body language, or approaching too quickly. Standing over someone, making direct eye contact in a confrontational posture, or issuing commands rather than offering choices can all escalate a tense situation.

De-escalation begins with the caregiver’s own emotional regulation. If you are frustrated, frightened, or angry, the person with dementia will sense it and mirror it. Step back. Lower your voice. Slow your movements. Use short, simple sentences. Say the person’s name. Avoid arguing, correcting, or reasoning — these require cognitive functions that are no longer reliably available. Instead, acknowledge the emotion: “You seem upset.

I want to help you feel better.” Redirect attention to something pleasant — a favorite song, a snack, a walk outside, or looking at photographs. Behavioral therapy approaches adapted for dementia have shown measurable results in reducing aggressive episodes. Structured interventions that identify the antecedent, behavior, and consequence — the ABC model — help caregivers and clinicians pinpoint patterns and develop targeted responses. For more on this approach, see Why do people with dementia improve with behavioral therapy to reduce aggression? and The Role of Cognitive Behavioral Therapy in Reducing Aggression in Dementia. When agitation becomes frequent or severe, it is essential to document the episodes systematically. Note the time of day, what was happening immediately before and after, who was present, and what the environment was like. Patterns almost always emerge. Perhaps agitation peaks in the late afternoon due to sundowning. Perhaps it only occurs with a specific caregiver whose approach needs adjustment.

Perhaps it coincides with constipation or a medication change. Documentation transforms guesswork into evidence, and evidence makes effective intervention possible.

Wandering: Prevention and Safety Strategies

Wandering affects approximately 60 percent of people with dementia at some point during the disease and is one of the most dangerous behavioral symptoms. A person who wanders and becomes lost faces risks of exposure, dehydration, traffic injuries, and death. The Alzheimer’s Association reports that if a person with dementia who wanders is not found within 24 hours, up to half will suffer serious injury or death. This is a behavior that demands proactive planning, not just reactive response. Wandering is driven by multiple factors. Some people wander because they are searching for something — a deceased spouse, a childhood home, a workplace they reported to for 30 years. Others wander because they are restless, bored, or experiencing physical discomfort such as the need to use a bathroom they cannot locate.

Still others wander because the part of the brain that governs spatial orientation has deteriorated, and they literally do not know where they are, even in familiar surroundings. Understanding the motivation behind wandering is essential for choosing the right intervention. Prevention strategies should operate on multiple levels. Environmental modifications include door alarms, motion-sensor alerts, childproof locks placed high or low where a person with dementia is less likely to look, and visual barriers such as dark mats in front of exits, which some individuals perceive as holes and avoid. GPS tracking devices worn as watches, shoe inserts, or clip-on devices provide a critical safety net when prevention fails. Registration with programs like MedicAlert and the Alzheimer’s Association’s Safe Return program ensures that if a person is found by emergency responders, their identity and condition can be quickly established. For comprehensive strategies on managing this risk, see How to Manage Wandering and Reduce the Risk of Getting Lost.

Routine and engagement are among the most effective preventive tools. A person who is meaningfully occupied is less likely to wander. Regular exercise, structured activities, and consistent daily schedules reduce restlessness. When a person does begin to wander, avoid physically restraining them unless there is an immediate safety threat. Walk with them. Gently redirect. Offer a snack or a preferred activity.

If wandering is driven by a belief that they need to go to work or pick up a child, validate the feeling rather than correcting the factual error: “That sounds important. Let’s have some tea first, and then we can figure it out together.” This approach respects the person’s emotional reality while buying time for the impulse to pass.

Wandering: Prevention and Safety Strategies

Hallucinations and Delusions in Dementia

Hallucinations and delusions are among the most misunderstood behavioral symptoms in dementia. Hallucinations involve perceiving something that is not there — most commonly visual hallucinations such as seeing people, animals, or objects, though auditory, tactile, and olfactory hallucinations can also occur. Delusions are fixed false beliefs, such as the conviction that a spouse is an imposter, that caregivers are stealing, or that deceased relatives are still alive. Research indicates that hallucinations and delusions affect 30 to 50 percent of people with dementia, with prevalence varying significantly by dementia type. For a foundational overview, see Why do people with dementia have hallucinations and delusions. The neurological basis of these symptoms differs across dementia types. In Lewy body dementia, disruptions to visual processing pathways and the neurotransmitter acetylcholine produce vivid, detailed hallucinations that may include well-formed figures of people or animals. In Alzheimer’s disease, delusions are more common than hallucinations and often involve themes of theft, infidelity, or persecution.

In some cases, what appears to be a hallucination is actually a misidentification — the person mistakes a coat on a rack for a person or misinterprets a shadow as an intruder. For broader context on understanding these experiences, see Understanding and Managing Hallucinations and Delusions and Hallucinations and delusions. The single most important principle in responding to hallucinations and delusions is this: do not argue. The experience is real to the person. Telling someone that the child they see in the corner does not exist will not change their perception. It will only make them feel dismissed, confused, or frightened. Instead, acknowledge the emotion. If the person seems afraid, provide reassurance: “I can see that’s scary.

You’re safe here with me.” If the hallucination is neutral or pleasant — such as a deceased parent visiting — there may be no need to intervene at all. For practical redirection techniques, see How to gently redirect a hallucination and How do you respond to delusions or hallucinations in someone with Alzheimer’s. When hallucinations or delusions are distressing, dangerous, or persistent, environmental and medical interventions become necessary. Reducing visual clutter, improving lighting to minimize shadows, turning off television programs that might be confused with reality, and removing mirrors that cause misidentification can all help. If symptoms arise suddenly or worsen acutely, consider medical causes such as urinary tract infections, dehydration, medication side effects, or other infections. For guidance on acute-onset psychotic symptoms during illness, see What should you do if a person with dementia develops new hallucinations, delusions, or paranoia during illness. Pharmacological management may be warranted in severe cases, a topic explored in depth in How to Use Medication to Manage Dementia-Related Hallucinations and Delusions. For nurses and professional caregivers, additional clinical guidance is available in Handling Hallucinations and Delusions: A Nurse’s Guide.

Anxiety and Fearfulness

Anxiety is one of the most pervasive yet underrecognized behavioral symptoms in dementia. Studies suggest that clinically significant anxiety affects 30 to 50 percent of people with Alzheimer’s disease and related dementias, though it is frequently masked by or attributed to other symptoms such as agitation or resistance to care. For a person whose ability to understand, predict, and control their environment is steadily eroding, anxiety is not pathological — it is a rational emotional response to a terrifying situation. Anxiety in dementia manifests in many forms. Some individuals become visibly fearful, clinging to a caregiver and becoming distressed when that person leaves the room or even moves out of sight. Others develop anticipatory anxiety about events such as bathing, medical appointments, or being left alone.

Repetitive questioning — “When are we going home?” “Where is my mother?” — is often driven by anxiety rather than simple memory failure. The person is not merely forgetting the answer; they are re-experiencing the distress that prompted the question each time it arises. Catastrophic reactions, in which a person becomes suddenly and intensely upset over what seems like a minor event, are frequently anxiety responses triggered when cognitive demands exceed remaining capacity. Non-pharmacological strategies are the first line of treatment for anxiety in dementia and can be remarkably effective. Maintaining consistent routines, providing gentle verbal reassurance, and using a calm and unhurried tone all help reduce the frequency and severity of anxious episodes. Physical presence is powerful — sitting beside the person, holding their hand, or offering a warm blanket can provide comfort that words cannot.

Structured activities that provide a sense of purpose and predictability are also beneficial. Research has shown that repetitive, rhythmic tasks such as folding laundry, sorting objects, or gentle rocking can significantly reduce anxiety in people with dementia. To understand the science behind this phenomenon, see Why do people with dementia show reduced anxiety when participating in repetitive, calming tasks like folding towels or sorting cards? and The Role of Repetitive Movement in Calming Dementia-Related Anxiety. When anxiety is severe, persistent, or significantly impairs daily functioning, a conversation with the person’s physician is warranted. Non-benzodiazepine anxiolytics, certain antidepressants, and in some cases low-dose antipsychotics may be considered, though all carry risks in older adults with dementia and should be used at the lowest effective dose for the shortest possible duration. Cognitive behavioral therapy principles, adapted for the person’s cognitive level, can also be helpful, particularly in earlier stages.

For more detail on therapeutic approaches to anxiety and depression, see Tell me about cognitive behavioral therapy for depression and anxiety.

Anxiety and Fearfulness

Depression and Social Withdrawal

Depression is both a risk factor for dementia and one of its most common behavioral symptoms. Research from the Alzheimer’s Association estimates that up to 40 percent of people with Alzheimer’s disease experience significant depression, though the true prevalence may be higher because depression in dementia is notoriously difficult to diagnose. The person may not be able to articulate feelings of sadness, hopelessness, or worthlessness. Instead, depression may manifest as loss of interest in previously enjoyed activities, reduced appetite, sleep disturbances, increased irritability, social withdrawal, or a general flattening of emotional expression that caregivers sometimes misinterpret as disease progression rather than a treatable condition. Social withdrawal is closely linked to depression but can also be driven by other factors, including sensory deficits such as hearing loss that make conversation difficult, embarrassment about cognitive difficulties, overstimulating environments that the person avoids because they feel overwhelming, and apathy — a neurologically distinct symptom from depression that involves reduced motivation without necessarily involving sadness. Distinguishing between depression, apathy, and the general cognitive decline of dementia requires careful observation and often professional assessment.

Caregivers can take several practical steps to address depression and withdrawal. First, maintain social engagement, but adjust expectations. One-on-one interactions in quiet settings are often more successful than group activities. Activities that draw on preserved long-term memories — looking at old photographs, listening to music from the person’s youth, or visiting familiar places — can spark engagement when other approaches fail. Physical activity, even gentle walking, has robust evidence supporting its antidepressant effects in older adults with and without dementia. Exposure to natural light, maintaining regular sleep-wake cycles, and ensuring adequate nutrition also support mood regulation.

Professional treatment should be considered when depression is moderate to severe. Antidepressant medications, particularly selective serotonin reuptake inhibitors, are commonly used in dementia-related depression, though their efficacy in this population is debated and response rates may be lower than in the general population. Psychotherapeutic approaches can be adapted for people with dementia, particularly in early and moderate stages. For more on therapeutic interventions for depression, see Tell me about cognitive behavioral therapy for depression and Tell me about cognitive behavioral therapy and depression. The key message for caregivers is that depression in dementia is not inevitable and not untreatable. It deserves the same clinical attention it would receive in any other population.

Repetitive Behaviors and Questions

Repetitive behaviors are among the most common experiences caregivers report, and while they are rarely dangerous, they can be profoundly wearing over time. These behaviors include asking the same question repeatedly, telling the same story multiple times in succession, pacing the same route, performing the same movement such as tapping or rubbing, and engaging in repetitive vocalizations such as calling out or humming. Understanding the mechanisms behind these behaviors makes them easier to tolerate and manage. Repetitive questioning is primarily a function of short-term memory loss. The person asks a question, receives an answer, and genuinely cannot retain the answer long enough to prevent the question from arising again. It is not attention-seeking behavior, nor is it a deliberate attempt to frustrate caregivers, though it can certainly feel that way after the fifteenth time.

In some cases, repetitive questions are also driven by underlying anxiety — the person senses that something is wrong or that something important is about to happen and the question is an expression of that unease rather than a true information request. Repetitive motor behaviors have a different and in some ways more complex neurological basis. Some repetitive movements are compulsive, driven by damage to frontal lobe circuits that govern behavioral inhibition, and are particularly common in frontotemporal dementia. Others are self-soothing behaviors — the neurological equivalent of a child rocking — that help regulate an internal state of discomfort or anxiety. Still others may be tied to procedural memory, which is often preserved long after declarative memory has failed. A person who spent decades knitting, sewing, or working with their hands may engage in repetitive hand movements that echo those ingrained motor patterns.

Management strategies for repetitive behaviors depend on the underlying cause. For repetitive questions driven by memory loss, written signs with answers to common questions (such as “Lunch is at noon” or “Your daughter is visiting on Sunday”) can reduce the frequency. Responding to the emotion behind the question rather than the literal content is also effective. If someone asks “When are we going home?” twenty times, the answer they need may not be a time — it may be reassurance that they are safe and cared for. For repetitive motor behaviors that are not distressing to the person, the most effective strategy may be to allow them. If the behavior is calming and not harmful, interrupting it may cause more agitation than tolerating it.

For more on how repetitive activities can serve a therapeutic purpose, see Why do people with dementia show reduced anxiety when participating in repetitive, calming tasks like folding towels or sorting cards?.

Repetitive Behaviors and Questions

Resistance to Personal Care

Resistance to personal care — bathing, dressing, toileting, grooming, and dental care — is one of the most consistently reported behavioral challenges across all stages and types of dementia. Studies suggest that over 70 percent of people with moderate to severe dementia will resist at least one aspect of personal care, with bathing being the most commonly resisted activity. For caregivers, particularly family members who are providing intimate care to a spouse or parent, these encounters can be emotionally devastating. The reasons for resistance are numerous and overlapping. The person may not understand what is happening or why. They may feel cold, exposed, or frightened. They may perceive the caregiver’s touch as threatening, especially if they have a history of trauma. They may be experiencing pain that is worsened by movement or water contact. They may be asserting the only autonomy they have left in a life where nearly every decision is now made for them.

In many cases, the resistance is not about the care task itself — it is about how, when, and by whom it is being delivered. Practical strategies for reducing resistance center on preserving dignity and maximizing the person’s sense of control. Offer choices wherever possible: “Would you like to wash your face or your hands first?” Use consistent routines so the person can anticipate what comes next. Warm the bathroom before bathing. Use a handheld showerhead rather than overhead water, which can feel disorienting or frightening. Cover the person with a towel during bathing to maintain warmth and modesty. Break tasks into small steps and provide one instruction at a time. Match your pace to theirs. If the person becomes agitated, stop.

Wait. Try again later. Forcing care in the face of resistance almost always makes the next attempt harder. Timing and framing matter enormously. A person who resists bathing at 7 AM may accept it at 2 PM. A person who refuses to “take a shower” may agree to “freshen up.” Using familiar language from the person’s own history — the words their generation used for hygiene activities — can reduce confusion. Singing familiar songs during care, playing music, and maintaining a warm and conversational tone can distract from the discomfort of the task. Some caregivers find that preparing everything in advance and minimizing the number of transitions and steps reduces the window during which resistance builds. When resistance is severe and persistent, consult with an occupational therapist who specializes in dementia care.

They can assess the specific barriers, recommend adaptive equipment, and train caregivers in techniques that reduce confrontation while maintaining hygiene and health.

Non-Pharmacological Behavior Management Techniques

Non-pharmacological interventions are universally recommended as the first-line approach to managing behavioral symptoms in dementia. This is not merely a philosophical preference — it reflects a substantial body of evidence showing that these approaches are effective, carry no side effects, and in many cases outperform medications. A landmark meta-analysis published in the British Medical Journal in 2012 found that non-pharmacological interventions had moderate to large effect sizes for reducing agitation and other behavioral symptoms, comparable to or exceeding the effects of antipsychotic medications without the associated risks of stroke, falls, and death. Music therapy is one of the best-studied non-pharmacological interventions. Personalized music — songs that are meaningful to the individual based on their life history — has been shown to reduce agitation, improve mood, and facilitate social engagement even in people with advanced dementia. The mechanism is thought to involve preserved neural pathways for music processing and the strong emotional associations that music carries. Creating a personalized playlist and playing it during times of known agitation, during personal care, or as part of a daily routine is an accessible and powerful tool.

Environmental design plays a critical role. Reducing noise, ensuring adequate but not harsh lighting, minimizing clutter, providing clear visual cues for navigation, and creating spaces that are both safe and stimulating contribute to behavioral stability. Access to outdoor spaces, gardens, and natural light has been associated with reduced agitation and improved sleep-wake patterns. The concept of creating a “prosthetic environment” — one that compensates for cognitive losses rather than highlighting them — is foundational to modern memory care design. Structured activities tailored to the person’s remaining abilities, interests, and life history are consistently effective. These include art and craft activities, gardening, pet therapy, reminiscence therapy using photographs and familiar objects, gentle exercise programs, and sensory stimulation such as aromatherapy and tactile materials. The key is matching the activity to the person’s current functional level.

An activity that is too difficult provokes frustration; one that is too simple feels patronizing. The sweet spot is an activity that engages without overwhelming. Caregiver education and training deserve special emphasis. Research consistently shows that when caregivers — whether family or professional — receive structured training in communication techniques, behavioral analysis, and person-centered care approaches, behavioral symptoms decrease. This is not because the disease changes, but because the interaction between the person and their environment improves. Programs such as the DICE approach (Describe, Investigate, Create, Evaluate) developed at Johns Hopkins provide frameworks that any caregiver can learn and apply. For additional perspectives on therapeutic approaches, see Tell me about cognitive behavioral therapy examples for depression.

Non-Pharmacological Behavior Management Techniques

When to Seek Professional Help for Behavioral Crises

While many behavioral symptoms in dementia can be managed effectively at home with knowledge, preparation, and support, there are situations that require professional intervention. Recognizing when a behavioral change has crossed from manageable to dangerous — to the person with dementia, to caregivers, or to others — is a critical skill that can prevent harm and even save lives. Seek immediate medical attention when behavioral changes are sudden and severe. A person who was calm yesterday and is acutely agitated, confused, or aggressive today may be experiencing delirium, which is a medical emergency. Delirium in dementia is most commonly caused by infections (particularly urinary tract infections and pneumonia), medication changes or interactions, dehydration, constipation, pain, or metabolic disturbances.

Delirium superimposed on dementia carries high mortality risk and requires prompt evaluation and treatment. New or sudden hallucinations, delusions, or paranoia during an acute illness should be evaluated urgently. For guidance on this specific scenario, see What should you do if a person with dementia develops new hallucinations, delusions, or paranoia during illness. Professional consultation is also warranted when behavioral symptoms persist despite consistent non-pharmacological interventions, when the person is at risk of harming themselves or others, when the caregiver is at risk of burnout or harm, or when medication management is needed. Geriatric psychiatrists, geriatricians, and neurologists with dementia expertise can conduct comprehensive behavioral assessments, review medications for potential contributors, and recommend targeted pharmacological interventions when appropriate.

For more detail on the role of medications in managing psychotic symptoms, see How to Use Medication to Manage Dementia-Related Delusions and Hallucinations. Caregivers should also have a crisis plan in place before a crisis occurs. This includes knowing the number for local crisis services, having a list of the person’s current medications and medical conditions readily available, knowing which emergency department in the area has geriatric or psychiatric expertise, and having a backup care plan for if the primary caregiver is incapacitated. Support groups, respite care, and caregiver counseling are not luxuries — they are essential components of sustainable dementia care. A caregiver who is sleeping four hours a night, has not seen their own physician in two years, and has no social support is not in a position to manage behavioral crises safely.

Professional help for the caregiver is professional help for the person with dementia. For daytime management of persistent psychotic symptoms, additional strategies and considerations are discussed in How can I manage hallucinations or delusions during the day? and Managing hallucinations and delusions in dementia.

Conclusion

Managing behavioral symptoms in dementia is not about controlling a person. It is about understanding them. Every behavior — whether it is agitation, wandering, hallucination, resistance, repetition, or withdrawal — is communication. The person with dementia is telling you something about their internal state, their unmet needs, their fears, or their discomfort. The caregiver’s task is to become fluent in this language, even when the words are gone.

The strategies outlined in this guide share a common foundation: person-centered care. This means knowing the individual behind the diagnosis, anticipating their needs, adapting the environment to support their remaining abilities, and responding to the emotion rather than the behavior. Non-pharmacological interventions should always be tried first and maintained even when medications are added. Medications have a role, but they are one tool among many, and they carry real risks in this population. The most powerful intervention available to any caregiver is their own presence, patience, and willingness to see the person rather than the disease.

No one should navigate this alone. Dementia care is a team effort that may involve family members, professional caregivers, physicians, therapists, social workers, and community resources. Seeking help is not a sign of failure — it is a sign of competence. The goal is not to eliminate all behavioral symptoms, which is neither possible nor always necessary. The goal is to reduce suffering, maintain safety, preserve dignity, and sustain the relationship between the person with dementia and the people who care for them.

That is achievable, and this guide is here to help you do it.

Frequently Asked Questions

What is the most common behavioral symptom in dementia?

Apathy is the single most common behavioral symptom, affecting up to 70 percent of people with dementia across all stages. However, agitation, anxiety, depression, and sleep disturbances are also extremely prevalent, and most individuals will experience multiple behavioral symptoms during the course of the disease.

Why does my loved one with dementia become more agitated in the late afternoon and evening?

This phenomenon, known as sundowning, affects an estimated 20 to 45 percent of people with dementia. It is thought to be related to disruption of the circadian rhythm, fatigue accumulated over the day, reduced lighting that increases confusion, and overstimulation. Strategies include increasing afternoon light exposure, maintaining a calm environment in the evening, ensuring the person is not overtired or hungry, and establishing a predictable evening routine.

Should I correct my loved one when they are hallucinating?

No. Arguing with or correcting a hallucination will not change what the person is perceiving and will likely increase their distress. Instead, acknowledge their experience, provide reassurance, and gently redirect if the hallucination is frightening. Only intervene actively if the hallucination is causing the person to do something dangerous. For specific techniques, see How to gently redirect a hallucination.

Are antipsychotic medications safe for people with dementia?

Antipsychotic medications carry significant risks in people with dementia, including an increased risk of stroke, falls, sedation, and death. The FDA has issued a black box warning regarding the use of antipsychotics in elderly patients with dementia. However, in cases of severe psychosis, aggression that poses a safety risk, or marked distress that has not responded to non-pharmacological approaches, the potential benefits may outweigh the risks. These decisions should be made in close consultation with a physician experienced in geriatric care.

How do I handle repetitive questions without losing my patience?

Recognize that the person is not doing this intentionally. They cannot retain the answer due to short-term memory failure. Try providing written answers to common questions posted where the person can see them. Respond to the underlying emotion rather than the literal question. If the question is driven by anxiety, provide reassurance. Take breaks when you need to, and do not feel guilty about briefly walking away to collect yourself.

When does wandering become an emergency?

Wandering becomes an emergency when the person leaves a safe area and cannot be located, when weather conditions pose a risk of hypothermia or heat stroke, when the person is near traffic or water, or when they are missing and time is passing. Call 911 immediately if a person with dementia who wanders is not found within 15 to 30 minutes. Prevention is always preferable to response — GPS tracking devices and door alarms should be in place before the first wandering episode occurs.

My mother with dementia refuses to bathe. How can I help her?

Resistance to bathing is extremely common and usually driven by fear, discomfort, loss of privacy, or confusion about what is happening. Try warming the bathroom in advance, using a handheld showerhead, covering exposed skin with a towel for warmth and modesty, offering choices, and attempting bathing at different times of day. Use language that is familiar and non-threatening. If full bathing is refused, a sponge bath or targeted cleaning of essential areas is an acceptable alternative that maintains hygiene without provoking a confrontation.

Can exercise help reduce behavioral symptoms?

Yes. Multiple studies have demonstrated that regular physical activity — including walking, gentle stretching, chair exercises, and dance — reduces agitation, improves mood, enhances sleep quality, and decreases the frequency of behavioral disturbances. Exercise does not need to be vigorous to be beneficial. Even 20 to 30 minutes of walking several times per week has measurable effects. The key is consistency and matching the activity to the person’s physical capabilities.

Is it normal for someone with dementia to become a completely different person?

Personality changes are common in dementia, particularly in frontotemporal dementia where the brain regions governing social behavior and personality are affected early. A person who was gentle may become aggressive. A previously cautious person may become impulsive. These changes are a direct result of brain damage and are not a reflection of the person’s “true” character. Understanding that the disease is driving the change, rather than the person choosing it, is essential for maintaining compassion and the caregiving relationship.

How do I know if a behavioral change is caused by pain?

People with moderate to advanced dementia often cannot verbalize pain. Look for behavioral cues including facial grimacing, guarding a body part, increased agitation during movement or personal care, changes in appetite, sleep disturbances, moaning or crying out, and withdrawal. Use a validated pain assessment tool designed for non-verbal individuals, such as the PAINAD scale. A trial of scheduled pain relief, such as regular acetaminophen, can be both diagnostic and therapeutic — if agitation decreases with pain treatment, pain was likely a contributing factor.
