Key Takeaway
Consider person-centered non-pharmacological interventions as a primary strategy for reducing verbal agitation in dementia.

This meta-analysis evaluates the efficacy of person-centered non-pharmacological interventions compared to control conditions for managing agitation in individuals with dementia. The analysis synthesized data across several outcomes, including overall agitation, verbal agitation, and two types of physical agitation.

The primary finding is a significant reduction in overall agitation (SMD = -0.48; 95% CI: -0.84 to -0.13, p = 0.008). Specifically, verbal agitation was significantly reduced (SMD = -0.45; 95% CI: -0.73 to -0.17, p = 0.002). However, reductions in physical non-aggressive agitation (SMD = -0.48) and physical aggressive agitation (SMD = -0.40) did not reach statistical significance.

The authors note substantial heterogeneity for overall agitation and both physical agitation subtypes. The lack of significant results for specific physical behaviors suggests a need for more targeted research in those areas. These findings support the use of personalized, non-pharmacological interventions as a first-line strategy, particularly when managing verbal symptoms in patients with dementia.

How this fits prior evidence

This meta-analysis addresses a gap in management strategies for behavioral symptoms in dementia. While previous coverage noted that pain assessment guidelines for cognitively impaired older adults lack practical detail, this finding provides evidence for non-pharmacological interventions to manage agitation. It specifically supports the use of personalized interventions as a first-line strategy for verbal symptoms.

Caring for a loved one with dementia can be incredibly stressful when they experience moments of agitation. For many families, finding ways to calm these episodes without relying solely on medication is a top priority. New research looks at how person-centered interventions—care that focuses on the specific needs and preferences of the individual—can make a difference.

The analysis found that these personalized approaches significantly reduced overall agitation in people with dementia. Specifically, it was very effective at reducing verbal agitation. While the study also looked at physical movements, the results for non-aggressive and aggressive physical behaviors were not consistent enough to be certain of their impact. This highlights how much more we need to learn about managing physical symptoms.

Because these methods focus on the person rather than just the symptoms, they are often recommended as a first step for managing verbal issues. However, because the data for physical agitation was varied and less clear, researchers say more specific studies are needed to understand those behaviors better. Talk to a doctor about how personalized care plans can support your loved one's daily well-being.

What this means for you:
Person-centered care significantly reduces overall and verbal agitation in people with dementia.

Common questions

What is a person-centered intervention?

A person-centered intervention is a type of care that focuses on the unique needs, preferences, and history of the individual. Instead of just treating a symptom like agitation, these methods aim to improve the quality of life by tailoring the environment and support to the specific person living with dementia.

Does this approach help with verbal agitation?

Yes. The research found that person-centered interventions significantly reduced verbal agitation in people with dementia. This makes these personalized methods a strong first-line strategy for managing patients who experience verbal symptoms of distress or agitation.

Does this treatment work for physical aggression?

The study did not find enough evidence to say if these interventions significantly reduced physical aggressive agitation. Because the results for different types of physical movements were inconsistent, more research is needed specifically targeting those behaviors.

ObjectiveThis meta-analysis aimed to evaluate the overall efficacy of person-centered non-pharmacological interventions for agitation in dementia and to compare treatment effects across behavioral subtypes, specifically physical aggressive agitation, physical non-aggressive agitation, and verbal agitation.MethodsA systematic literature search was conducted in PubMed, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials (CENTRAL) from database inception to March 2026. Randomized controlled trials (RCTs) evaluating person-centered non-pharmacological interventions for agitation in individuals with dementia were included. The primary outcome was agitation, with subgroup analyses performed for behavioral subtypes. Standardized mean differences (SMDs) with 95% confidence intervals (CIs) were calculated using random-effects models. Risk of bias was assessed using the Cochrane RoB 2.0 tool.ResultsSix RCTs were included. Person-centered non-pharmacological interventions significantly reduced overall agitation compared with control conditions (SMD = −0.48, 95% CI: −0.84 to −0.13, p = 0.008; I2 = 81%). Subgroup analyses revealed a significant reduction in verbal agitation (SMD = −0.45, 95% CI: −0.73 to −0.17, p = 0.002; I2 = 0%), whereas reductions in physical non-aggressive agitation (SMD = −0.48, 95% CI: −1.06 to 0.11, p = 0.11; I2 = 84%) and physical aggressive agitation (SMD = −0.40, 95% CI: −1.63 to 0.83, p = 0.52; I2 = 86%) did not reach statistical significance. Substantial heterogeneity was observed for overall agitation and physical agitation subtypes, but not for verbal agitation.ConclusionPerson-centered non-pharmacological interventions significantly reduce overall agitation in individuals with dementia, with the most consistent effects observed for verbal agitation. The lack of significant effects on physical agitation subtypes, coupled with substantial heterogeneity, highlights the critical need for further research and intervention development specifically targeting these physical behaviors. These findings support the use of personalized interventions as a first-line strategy, particularly for verbal symptoms, while emphasizing the importance of further research to optimize interventions for physical agitation.Systematic review registrationhttps://www.crd.york.ac.uk/PROSPERO/view/CRD420261363075, identifier PROSPERO (CRD420261363075).
