You can usually tell that someone with dementia is in pain by watching for changes rather than waiting for words: grimacing, guarding a body part, moaning, restlessness, aggression, refusing food, resisting care, or withdrawing from activities they normally enjoy. Because dementia progressively erodes the ability to describe sensations, pain in this population most often shows up as behavior, not complaint. Caregivers who look for a shift from the person’s baseline — a normally calm mother who suddenly lashes out during bathing, for example — are far more likely to catch pain than those who rely on the question “Does it hurt?” Consider a common real-world scenario: a man with moderate Alzheimer’s disease begins pacing at night, striking out when staff try to reposition him, and eating half of what he used to. Staff assume the dementia is “getting worse” and request a sedative.
A careful exam later reveals an untreated urinary tract infection and an arthritic hip. Once the infection is treated and scheduled pain relief started, the pacing and aggression largely resolve. This pattern — pain misread as worsening dementia or “difficult behavior” — is one of the most frequent and consequential mistakes in dementia care. The reliable approach combines three things: knowing the person’s baseline, using a structured observational pain tool during movement (not just at rest), and treating suspected pain as a medical question that deserves investigation, not just behavioral management.

What Are the Signs That Someone With Dementia Is in Pain?
Pain signals in dementia cluster into a handful of observable categories. Facial expressions are among the most reliable: frowning, grimacing, rapid blinking, a tightened or frightened look, or clenched teeth. Vocalizations matter too — moaning, groaning, sighing, calling out, or repetitive verbalizations like “help, help, help” that intensify with movement. Body language offers another window: guarding a limb, rubbing a body part, rigid posture, fidgeting, pacing, rocking, or resisting being moved. Behavioral and functional changes are equally telling but easier to miss because they develop gradually.
A person in pain may stop walking to the dining room, sleep more or less than usual, refuse meals, become irritable or combative during personal care, or withdraw socially. Compare two residents: one who has always disliked showers and resists them consistently, and another who tolerated showers for months and suddenly begins screaming when her arm is lifted. The first is a preference; the second is a red flag for something like a shoulder injury or arthritis flare. Physiological signs — sweating, pallor, rapid breathing, elevated pulse — can accompany acute pain, but they are unreliable for chronic pain, which is far more common in older adults. Chronic pain from arthritis, old fractures, neuropathy, or dental disease often produces no vital-sign changes at all, which is precisely why observation of behavior and function carries so much weight.
Why People With Dementia Underreport Pain
Dementia damages the brain networks needed to recognize, remember, and communicate pain — but it does not eliminate the experience of pain itself. Research on pain processing in Alzheimer’s disease suggests that the sensory experience of pain remains largely intact even as the ability to interpret and report it declines. A person may feel a toothache acutely yet be unable to name it, locate it, or remember it long enough to tell anyone. When asked “Are you in pain?” they may sincerely answer “No” because the question requires abstract self-reflection and recall that the disease has taken away. Word-finding problems compound this. someone in pain may say they feel “funny,” “tired,” or “bad,” or may use an unexpected word entirely.
Others express distress through behavior alone: a woman with advanced dementia who repeatedly slaps her own jaw may be signaling dental pain she cannot verbalize. Studies of nursing home populations have consistently found that residents with dementia receive less analgesia than cognitively intact residents with the same painful diagnoses — such as after hip fracture — which points to systematic under-recognition rather than less pain. An important limitation: none of these behavioral signs is specific to pain. Agitation can also stem from hunger, constipation, boredom, fear, a noisy environment, medication side effects, or the dementia itself. That ambiguity cuts both ways — it means caregivers should neither dismiss behavior as “just the dementia” nor reflexively medicate every episode with painkillers. The behavior is a prompt to investigate, not a diagnosis.
Using Observational Pain Assessment Tools
Structured tools turn scattered impressions into something trackable. The most widely used is PAINAD (Pain Assessment in Advanced Dementia), which scores five items — breathing, negative vocalization, facial expression, body language, and consolability — each from 0 to 2, for a total of 0 to 10. A score above a low threshold suggests pain warranting intervention. Other validated instruments include the Abbey Pain Scale, often used in hospice and residential care, and PACSLAC (Pain Assessment Checklist for Seniors with Limited Ability to Communicate), a longer checklist that captures subtler changes. The critical technique with any of these tools is to assess during movement, not only at rest.
Chronic musculoskeletal pain — the most common type in older adults — may be invisible while a person sits quietly and obvious the moment they stand, transfer, or have a limb moved. A practical example: a PAINAD assessment done while a resident watches television scores 1, but the same assessment during a transfer from bed to wheelchair scores 6, with grimacing, moaning, and bracing. The second score is the meaningful one. For people with mild to moderate dementia, don’t abandon self-report entirely. Many can still answer a simple yes/no question asked in the moment (“Does your knee hurt right now?”) or point to a body part, even if they can’t use a 0-to-10 scale. Best practice is to attempt self-report first, then layer observational tools on top.
What Caregivers Should Do When They Suspect Pain
Start with detective work before medication. Check the obvious, fixable causes: constipation (track bowel movements), urinary retention or infection, ill-fitting dentures or dental abscesses, pressure sores, skin tears under clothing, tight shoes, contractures, and recent falls that may have caused an unnoticed fracture. Review the person’s medical history — someone with documented osteoarthritis, diabetic neuropathy, or old vertebral fractures almost certainly still has those painful conditions, whether or not they mention them. Then involve a clinician and consider a structured approach many geriatricians use: an analgesic trial. If pain is suspected but unconfirmed, a scheduled, time-limited course of a simple analgesic — typically regular acetaminophen — is given while behavior is tracked.
If agitation, resistance to care, or withdrawal improves, that is strong evidence the behavior was pain-driven. Studies of stepped analgesic protocols in nursing home residents with dementia have shown meaningful reductions in agitation, in some cases comparable to what antipsychotics achieve, without the sedation and stroke risks those drugs carry. There is a genuine tradeoff to weigh. Undertreating pain condemns someone to suffering they cannot report and often triggers antipsychotic prescriptions for “behavior.” Overtreating carries its own risks: opioids in frail elders can cause falls, delirium, and constipation, and even NSAIDs pose kidney and gastrointestinal dangers in this population. The usual compromise is scheduled acetaminophen as the foundation, non-drug measures alongside it (heat, gentle repositioning, physical therapy), and stronger medication reserved for clearly identified, more severe pain — with regular reassessment rather than indefinite prescriptions.
When Pain Is Mistaken for “Behavioral Problems”
The costliest error in dementia care is labeling pain-driven behavior as a psychiatric symptom. Agitation, aggression, screaming, and resisting care are frequently treated with antipsychotics or sedatives — drugs that carry regulatory warnings about increased risk of stroke and death in elderly people with dementia. When the underlying problem is an arthritic knee or an abscessed tooth, sedation doesn’t relieve the pain; it merely silences the only alarm system the person has left. A warning sign that “behavior” is actually pain: it clusters around specific activities.
Aggression that occurs mainly during bathing, dressing, transfers, or wound care — moments when painful joints are moved or tender skin is touched — points strongly to pain. So does behavior that follows a daily pattern matching a condition, such as morning stiffness with arthritis or evening worsening with neuropathy. Randomly distributed agitation, by contrast, is more likely environmental or neuropsychiatric. Families should feel entitled to ask direct questions before any sedating medication is started: Has a pain assessment been done, including during movement? Has anyone examined the mouth, skin, abdomen, and joints? Has an analgesic trial been tried? In many facilities, these steps are required before antipsychotics can be justified for behavioral symptoms, but in practice they are sometimes skipped under time pressure.
Pain Assessment in Late-Stage Dementia
In advanced dementia, when speech is largely gone, assessment narrows to the finest signals: a furrowed brow during repositioning, a change in breathing rhythm, rigidity when a limb is moved, or an unusual cry. Consolability becomes a key test — distress that eases with a calm voice and hand-holding is more likely emotional, while distress that persists despite comfort measures suggests a physical cause. Hospice teams often rely on the Abbey Pain Scale or PAINAD at every care interaction rather than once a shift, because pain in immobile patients frequently comes from things staff do: turning, transferring, and dressing changes.
A concrete example from end-of-life care: a bedbound woman with late-stage dementia begins moaning each time she is turned. Staff pre-medicate with analgesia 30 to 60 minutes before repositioning and adjust the turning technique to support her contracted limbs. The moaning stops. Nothing about her dementia changed — only the recognition that routine care had become painful.
Common Sources of Hidden Pain in People With Dementia
Certain conditions account for a large share of undetected pain in this population. Osteoarthritis is the most prevalent — knees, hips, hands, and spine — and worsens predictably with movement. Dental problems are notoriously missed because people with dementia often can’t cooperate with oral exams and may not have seen a dentist in years; abscesses, broken teeth, and ulcers from ill-fitting dentures can cause food refusal that gets misattributed to the dementia.
Constipation, sometimes severe enough to cause fecal impaction, produces abdominal pain and dramatic agitation. Other frequent culprits include pressure injuries on the sacrum and heels, urinary tract infections, gout flares, diabetic nerve pain, and unrecognized fractures after unwitnessed falls — a person with dementia may walk on a fractured hip if the break is impacted, showing pain only as a new reluctance to bear weight. A basic head-to-toe check — mouth, skin, abdomen, joints, feet — during routine care catches many of these before they escalate.
Frequently Asked Questions
Can people with dementia still feel pain?
Yes. Dementia impairs the ability to recognize and report pain, but the sensory experience of pain remains largely intact even in advanced disease.
What is the PAINAD scale?
The Pain Assessment in Advanced Dementia scale scores breathing, vocalization, facial expression, body language, and consolability from 0 to 10, and is most accurate when used during movement.
Why does my relative deny pain but grimace when moving?
The question “Are you in pain?” requires memory and abstract self-reflection that dementia erodes. Behavior during movement is usually a truer signal than verbal answers.
Is aggression during bathing a sign of pain?
Often, yes. Resistance or aggression that clusters around bathing, dressing, or transfers frequently indicates painful joints or tender skin being moved or touched.
What is an analgesic trial?
A time-limited course of scheduled pain relief, usually acetaminophen, given while tracking behavior. If agitation or withdrawal improves, pain was likely the cause.
What hidden problems most often cause pain in dementia?
Arthritis, dental abscesses or ill-fitting dentures, constipation, urinary tract infections, pressure sores, and unrecognized fractures after falls.
