Caregivers should watch nonverbal pain cues because people with dementia often cannot tell you when they hurt, yet approximately 50 percent of those with dementia experience pain—a rate consistent with similarly aged people without dementia. When someone loses the ability to communicate verbally, pain becomes invisible unless you know what to look for. Consider a person with advanced dementia who suddenly becomes restless and agitated: a caregiver who attributes this to behavioral issues might miss the fact that a urinary tract infection or arthritis flare is causing significant pain. Without intervention, untreated pain leads to health deterioration, delayed recovery, worsened cognitive impairments, and increased mortality risk.
The challenge facing caregivers is fundamental: pain has no objective test. There is no blood work or scan that definitively measures whether someone is in pain. For nonverbal patients, we cannot rely on the simple question “Where does it hurt?” This means caregivers become the critical link between suffering and relief. A 2025 scoping review examining nearly 1,200 healthcare professionals and over 37,000 people with dementia across studies published between 2002 and 2024 found that pain assessment in nonverbal populations remains inconsistent and often inadequate. Learning to recognize and respond to nonverbal pain signals is not an optional skill for dementia caregivers—it is essential to preventing unnecessary suffering and protecting overall health.

Why Pain in Dementia Is So Often Missed
pain assessment in dementia care faces a critical gap: the very disease that causes cognitive decline also strips away the ability to communicate its symptoms. When someone can no longer use words, many caregivers—and even some healthcare providers—assume pain is less likely or less severe. This assumption is dangerous and incorrect. Research shows that pain rates in dementia are no lower than in older adults without cognitive impairment, yet pain goes unrecognized far more often. The problem compounds when you consider the complexity of dementia itself.
A person in mid-stage dementia might retain some ability to report pain through simple yes-or-no questions, but staff or family may not ask. A person in advanced dementia cannot answer any question about pain, forcing caregivers to rely entirely on behavioral observation. Many behavioral changes that seem like dementia itself—restlessness, agitation, withdrawal—are actually pain signals being misinterpreted. A study published in the Journal of Pain documented that approximately 50 percent of people with dementia experience pain, yet the recognition rate among caregivers and healthcare providers lags significantly behind. This gap between pain’s actual presence and its recognition remains one of the most troubling problems in dementia care.
The Nonverbal Language of Pain—What Caregivers Must Learn
Pain speaks through the body when words fail. Understanding this language requires learning to observe facial expressions, body movements, vocalizations, behavioral changes, and even physiological shifts that signal discomfort. Each type of signal offers clues about where and how much pain might be present. Facial expressions are often the first place to look. Grimacing, frowning, and a furrowed brow are nearly universal signs of pain. Watch for tightly shut eyes, pursed lips, or a clenched jaw—these muscular changes happen involuntarily when someone is hurting. Body language tells a complementary story. Someone in pain often guards the affected area, unconsciously protecting it from movement or touch. You might notice limping, a hunched posture, or reduced mobility overall.
Some people with dementia become restless or fidgety, constantly shifting position as though they cannot find comfort. Others withdraw and become still, moving minimally to avoid pain. Vocalizations—involuntary moaning, sighing, or groaning—can signal pain even when someone has lost the ability to say “it hurts.” Behavioral changes like writhing, panic attacks, appetite loss, or weight loss frequently accompany pain in nonverbal patients. Finally, physiological signs visible on the body include increased heart rate, rapid or shallow breathing, and sweating—all of which can indicate pain even when the person cannot report it. A critical limitation to remember: these signs can sometimes indicate other problems. Restlessness might signal a need to use the bathroom, confusion, or medication side effects. Withdrawal could reflect depression or fatigue. This is why caregivers must observe patterns and context, not react to any single sign in isolation. A person who is usually animated becoming withdrawn and motionless after a fall, combined with guarding behavior near the hip, suggests pain. The same withdrawal in a person who just had a medication change might warrant investigation into that change first.
Beyond Facial Expressions—The Full Picture of Pain Signals
While facial expressions catch immediate attention, a thorough assessment requires looking at the whole person. Hospice organizations and pain specialists have documented detailed profiles of how pain manifests in nonverbal populations, and this knowledge directly applies to dementia care. Body positioning offers constant feedback. Someone in pain often takes on what specialists call “protective posturing”—hunched shoulders, knees drawn up, or a bent spine that minimizes movement and protects sensitive areas. In contrast, untreated pain sometimes causes the opposite: writhing, inability to stay still, constant repositioning. A person who suddenly refuses to stand, sit, or move in ways they previously tolerated without complaint may be experiencing pain from arthritis, fractures, pressure wounds, or internal conditions. Behavioral escalation—where agitation increases in particular situations—provides additional diagnostic information. If someone becomes severely agitated during personal care (bathing, dressing, toileting), this strongly suggests pain in areas being touched or moved.
Compare this to agitation that occurs throughout the day regardless of activity, which might indicate other causes. Appetite changes represent another important signal. Pain commonly suppresses appetite, leading to reduced food intake and weight loss. This becomes especially serious in dementia care because nutritional decline accelerates cognitive and physical decline. Someone who previously ate well now refusing meals warrants investigation for pain, not just appetite loss. Weight loss combined with other behavioral changes strengthens the suspicion of underlying pain. The real-world challenge for caregivers is that dementia patients may lose appetite for many reasons—medication side effects, difficulty swallowing, depression, or simply the disease progression itself. This is why pain assessment requires pattern recognition and collaboration with healthcare providers, not guesswork.
Assessment Tools That Work When Words Are Gone
Fortunately, pain specialists have developed evidence-based tools specifically designed for nonverbal patients, and several show particular promise for dementia care. These tools translate observable behaviors into quantifiable pain assessments that can guide treatment decisions. The Pain Assessment in Advanced Dementia (PAINAD) scale stands as one of the most widely recommended tools for dementia care. It evaluates five categories: breathing, negative vocalization, facial expression, body language, and consolability. Each category is scored, producing a total that suggests pain level. The PAINAD is designed specifically for advanced dementia patients who cannot communicate verbally, making it highly relevant for caregivers. Another tool, the Critical Care Pain Observation Tool (CPOT), demonstrates high sensitivity and specificity in detecting pain among ICU patients who cannot communicate—a population with similar assessment challenges.
The Face, Legs, Activity, Cry, Consolability (FLACC) scale originated in pediatrics but has applications for nonverbal adults in certain settings. The Multidimensional Objective Pain Assessment Tool (MOPAT) has been identified as the only valid evidence-based tool specifically designed for nonverbal palliative care patients, offering comprehensive assessment across multiple dimensions. However, a major limitation exists that caregivers should understand: there is currently no single standardized tool recommended for broad clinical adoption across all dementia care settings. This means that different healthcare facilities, assisted living communities, and home care agencies may use different assessment tools or no formal tool at all. A caregiver might benefit from learning multiple tools to recognize pain assessment approaches across different care environments. Family caregivers who understand tools like PAINAD can communicate more effectively with healthcare providers. For example, tracking a patient’s PAINAD scores before and after medication changes or interventions provides objective data that guides clinical decisions. The American Society for Pain Management Nursing recommends a comprehensive, hierarchical approach—starting with simple yes-or-no pain questions for those who can answer them, then moving to behavioral observation tools when verbal communication fails.
Why Pain Often Goes Unrecognized—The Barriers Caregivers Face
Understanding nonverbal pain signals is necessary but not sufficient. Caregivers face real structural and systemic barriers to recognizing and addressing pain in dementia patients, and awareness of these obstacles can help overcome them. Staffing shortages in long-term care facilities mean that caregivers often have insufficient time to observe individual residents carefully. A nursing home aide responsible for twenty patients during a shift may not have the mental space or time to notice subtle changes in a particular person’s behavior or facial expression. Family caregivers at home face their own barriers: they may lack training in pain assessment, trust their instincts over formal observation, or dismiss behavioral changes as “just the dementia.” Some caregivers worry that reporting possible pain might lead to unnecessary medication, yet unmanaged pain itself increases mortality risk and hastens decline. The 2025 scoping review that examined nearly 1,200 healthcare professionals found concerning gaps in knowledge and practice.
Many professionals lack specific training in nonverbal pain assessment or access to validated tools. Cultural differences also matter—some caregivers and patients come from backgrounds where stoicism is valued and pain reporting is discouraged, making pain signals even more subtle and easier to miss. Another barrier is the attribution error: when someone with dementia shows behavioral changes, caregivers often attribute them to dementia itself rather than investigating potential underlying causes like pain. A person becomes “sundowning” or “having a bad day” when they might actually be experiencing pain from a urinary tract infection, constipation, or injury. This misattribution delays appropriate pain management and allows suffering to continue unnecessarily. Overcoming these barriers requires education, time, systematic observation, and willingness to investigate behavioral changes thoroughly rather than dismiss them as inevitable parts of the disease.
Physical Conditions That Commonly Cause Pain in Dementia
Caregivers should understand which conditions frequently cause pain in older adults and people with dementia, because recognizing patterns helps identify pain early. Some conditions are obvious; others are easy to miss. Arthritis affects a majority of older adults and causes significant pain, especially during movement. A person with dementia and arthritis might refuse to stand or walk, resist assistance with dressing or bathing, or show facial grimacing during these activities. Urinary tract infections (UTIs) are notoriously common in dementia care and frequently cause behavioral changes—agitation, restlessness, or confusion—that have nothing to do with dementia progression.
A sudden spike in agitation warrants a UTI test, not just a medication adjustment. Constipation, pressure wounds (bedsores), fractures from falls, dental pain, and infections all occur commonly in dementia populations and all cause pain that nonverbal patients cannot report directly. Aspiration pneumonia, gallbladder disease, and kidney stones are more serious conditions that nonetheless occur and cause pain. For each of these conditions, behavioral observation combined with medical investigation can identify pain and guide appropriate treatment. The lesson for caregivers is this: when behavior changes, pain is always worth investigating. A trial of pain medication combined with addressing the underlying cause often brings remarkable improvement in both pain and behavior.
Building a Pain-Aware Care Culture for Dementia
Recognizing nonverbal pain signals is only the first step; the second is creating a care environment where pain assessment and management are priorities rather than afterthoughts. This requires coordination among family members, healthcare providers, and care staff. Documentation and communication form the foundation of effective pain management in dementia care. A family caregiver who learns to use a tool like PAINAD can share observations with the person’s doctor, saying “I’ve been tracking pain using the PAINAD scale, and scores increase when my mother refuses food”—this is far more useful than “I think she’s in pain.” Healthcare providers gain crucial information from these observations and can adjust treatment accordingly.
Over time, as pain is recognized and managed effectively, behavioral problems often improve, quality of life increases, and the entire trajectory of care shifts. A person with dementia in pain who receives appropriate pain management may show improved mood, better appetite, increased engagement, and reduced agitation—improvements that benefit everyone involved in their care. The recognition of pain becomes self-reinforcing: when caregivers see that pain management improves outcomes, they invest more energy in careful observation and reporting. This emerging understanding about pain in dementia care, supported by research from 2002 through 2025, suggests a future where nonverbal pain assessment becomes as routine as taking someone’s blood pressure—not optional, not occasional, but fundamental to good care.
Conclusion
Caregivers who learn to recognize nonverbal pain signals become powerful advocates for people with dementia who cannot speak for themselves. The evidence is clear: approximately 50 percent of dementia patients experience pain, yet recognition lags far behind reality. By observing facial expressions, body language, vocalizations, behavioral changes, and physiological signs, caregivers can identify pain and report it to healthcare providers. Using tools like the PAINAD scale provides structure to observation and enables better communication with the medical team. The stakes are high—untreated pain leads to health deterioration, worsened cognitive decline, and increased mortality.
The path forward requires ongoing vigilance, education, and a commitment to investigating behavioral changes rather than dismissing them as inevitable parts of dementia. If you are a family caregiver, learn to recognize pain signals and ask your healthcare providers about assessment tools and pain management options. If you are a healthcare provider, prioritize nonverbal pain assessment in your practice and educate staff and families about what to watch for. If you work in long-term care, advocate for time and training to implement systematic pain assessment. Every person with dementia deserves to be as pain-free as possible, and that requires caregivers who know what to look for and act on what they see.
