The growing prevalence of dementia is a major global concern [1]. As the disease progresses, cognitive decline is often accompanied by the behavioral and psychological symptoms of dementia (BPSD) [2,3]. The International Psychogeriatric Association defines the BPSD as disturbances in perception, thought content, mood, or behavior [4]. These symptoms can be grouped into two subtypes: (1) behavioral symptoms, which are typically observed directly (agitation, verbal or physical aggression, wandering, sexual disinhibition, repetitive behavior, catastrophic reactions, sundowning, sleep problems, sleeplessness, and apathy), and (2) psychological symptoms, which are usually assessed through interviews with patients and relatives (psychosis, delusions, hallucinations, misidentifications, mood changes, anxiety, restlessness, and depression) [2,4]. BPSD has a deleterious impact on the quality of life of people with dementia, accelerating cognitive decline, reducing life expectancy, and precipitating hospitalizations and early placement in nursing homes [5,6]. Managing patients’ BPSD often requires constant vigilance, leading to heightened stress and depressive symptoms among informal caregivers. Furthermore, indirect costs, including medical consultations, nonreimbursed medication, home adaptations, and reduced professional activity, can lead to substantial socioeconomic burdens [7-9]. For health care professionals, BPSD can increase workloads, stress, and the risk of professional burnout, which may reduce the quality of the care provided [10,11]. Regarding the health care system overall, BPSD leads to higher costs due to more consultations, hospitalizations, and prescriptions of psychotropic drugs [12].

The etiopathogeneses of BPSD are complex and multifactorial, influenced by biopsychosocial and environmental factors, and vary considerably in frequency and intensity between individuals [13,14]. Their early detection through the identification of subtle behavioral and psychological changes (eg, apathy, anxiety, sleep problems, irritability, and social withdrawal), before any formal clinical intervention, is of major clinical importance [15,16]. Early identification enables proactive management and personalized interventions, thereby helping to mitigate the symptoms’ deleterious impact. However, early detection is challenging as early signs are often transient, underrecognized, and misinterpreted as normal aging or personality changes [15,16]. Furthermore, standard detection tools, such as the Neuropsychiatric Inventory, the Alzheimer’s Disease Behavioral Pathology Assessment Scale, or the Cohen-Mansfield Agitation Inventory, can be time-consuming, and health care professionals do not always perceive them to be precise or practical [11,14,17]. These challenges are exacerbated by growing demands for care and persistent shortages of qualified health care staff [18,19]. New health care technologies offer promising solutions to these challenges [20,21].

Recent technological developments have focused on artificial intelligence–based technologies (AITs), which combine artificial intelligence (AI) with remote sensors, robotics, and decision support algorithms [21-24]. AI encompasses a wide range of techniques and methodologies designed to enable computer systems to mimic human cognitive functions, such as learning, problem-solving, and decision-making [24]. When combined with critical thinking and human judgment, AI can optimize clinical reasoning by accelerating and refining assessment, anticipation, the synthesis of multiple data sources, and knowledge generation [25]. In health care, AI is already applied in diagnosis and screening, treatment personalization, patient monitoring, robot-assisted surgery, and health system management [22]. In dementia care, current AITs include monitoring systems, social robots, and daily living assistance tools, primarily involving wearable and environmental sensors [26-28]. These technologies have shown positive impacts on depression, quality of life, social engagement, cognitive function, and patient monitoring [26-28]. They have also demonstrated good performance in health monitoring and dementia screening [26-28].

Management of BPSD requires a multidisciplinary team, with nurses playing a key role in the early detection of symptoms, thanks to their continuous proximity with patients [4]. However, due to the complexity of these symptoms and the diversity of beliefs and conceptualizations regarding BPSD, it is not uncommon for nurses’ clinical judgments to be based on intuition and their standard practice rather than on a clear, standardized methodology [29,30]. This underscores the potential for introducing AITs to support clinical judgment and thus enhance the quality of nursing care for people with dementia. Registered and advanced practice nurses have been actively helping to develop and implement AITs in health care [31-33]. They engage in activities including problem-solving, defining contextual needs and formulating priorities, idea generation, finding concrete solutions, and determining end user satisfaction [31-33].

While previous reviews have examined the use of AITs in the care of patients with dementia and BPSD, their scope differed from this work [34-38]. Husebo et al [37] focused on treatment monitoring, and Jao et al [35] emphasized model performance without mapping contexts of use. AI has evolved rapidly since 2020, and it is likely that new solutions, not covered in these reviews, have now emerged. More recently, other authors have addressed the use of AITs in the general care of those with dementia and BPSD, combining prediction, assessment, and treatment, but without a specific focus on early detection [34,38]. Similarly, Shaik et al [36] reviewed remote sensing technologies and care frameworks without focusing on the application of AITs for the early detection of the BPSD. Our preliminary literature searches identified no completed or ongoing scoping reviews on the topic. Given the rapid evolution of AITs and their growing integration into dementia care, an updated and targeted synthesis of the literature is necessary.

This scoping review aimed to identify and summarize the different types of AITs currently available for the early detection of BPSD among older adults. It also sought to examine the functional uses of those technologies, the health care professionals involved, nursing involvement and experience with AITs, the care setting in which they are used, and the characteristics of the BPSD they assess. Our research questions were developed following the population, concept, and context framework. First, what type of AITs are currently available for the early detection of BPSD among people with dementia? Second, what are the functional uses of the AITs involved in the early detection of BPSD? Third, which health care professionals are involved in the use and implementation of AITs for the early detection of BPSD? Fourth, in which care settings are AITs used for the early detection of BPSD? Which specific characteristics of BPSD do AITs assess? Finally, what are nurses’ specific roles, responsibilities, and experiences regarding the use of AITs for the early detection of BPSD?

This scoping review was conducted in accordance with the Joanna Briggs Institute manual for scoping reviews [39]. The PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews; checklist provided in Checklist 1) standards were followed for reporting [40]. The scoping review’s protocol was registered at the Open Science Framework [41].

The eligibility criteria for studies with the potential to be assessed in this review were defined based on their population, concepts, and types of sources. The inclusion and exclusion criteria are detailed in Table 1.

In March 2025, we conducted a literature search of the following bibliographic databases in collaboration with a medical librarian (JRA): MEDLINE ALL Ovid, Embase, APA PsycInfo Ovid, CINAHL EBSCO, Web of Science Core Collection, the Cochrane Database of Systematic Reviews Wiley, the Cochrane Central Register of Controlled Trials Wiley, and ProQuest Dissertations and Theses A&I. No language or date restrictions were applied. The final search strategies were peer-reviewed by a second information specialist and are documented in Multimedia Appendix 1, detailing the search syntax, keywords, and index terms used. Using the studies that were retained, we performed a backward and forward citation search using Citationchaser [45] (SF). Further research was carried out in the Association for Computing Machinery Digital Library (SF).

After the search, a medical librarian (JRA) imported all the references identified into EndNote 20 (Clarivate Analytics), and duplicate references from the databases were removed using Deduklick (Risklick AG) [46]. The references were then imported into the Rayyan interface, and 2 reviewers (SF and CGdR) independently screened the titles and abstracts according to the established inclusion criteria. All the potentially relevant sources were retrieved in full and imported into a database. Two reviewers (SF and EP) then independently assessed the full texts of the references retained to ensure they met the inclusion criteria. The rationales for excluding references at the full-text review stage were documented. Disagreements between the reviewers during this selection process were discussed and resolved with the assistance of a third reviewer (HV). Due to resource constraints, the selection of references identified through citation tracking was conducted by a single reviewer (SF). The results are presented in a PRISMA-ScR flow diagram [47].

Data from the references retained for the scoping review were extracted by a single reviewer (SF), and a random 10% subset of the full-text articles included was verified by a second reviewer (HV) to ensure accuracy and completeness [48]. The second reviewer cross-checked the completed data extraction tool’s results against the corresponding full-text articles. Data were extracted using a data extraction tool developed in accordance with the study’s objectives and search questions. The data extracted included the year of publication, country of origin, study characteristics (design, objectives, sample size, health care setting, and health care professionals), participant characteristics (age, sex, and dementia type and severity), specific types of the AITs (sensors, social robots, and decision support systems), delivery methods for these AITs (remote monitoring platforms and mobile apps), the functional purposes of these AITs, the AI techniques applied, characteristics of the BPSD assessed, the traditional instruments used for detecting BPSD, nurses’ involvement and experience, and key findings relevant to the review questions (eg, effectiveness, usability, feasibility, users’ satisfaction with AITs, users’ perspectives about AITs, and barriers and facilitators to adopting AITs). When necessary, study authors were contacted to request missing or additional data.

We use a narrative approach to present the extracted and analyzed evidence in the different sections below [39]. The sections include (1) the characteristics of the included studies, (2) the types and uses of AITs, (3) the characteristics of the BPSD detected, and (4) the involvement and experience of nurses. The types of AITs were analyzed and categorized according to the definitions proposed by Zhang and Lu [49], which distinguish the different drivers and technologies of AI. Tables, charts, and diagrams are used to summarize and make the evidence more readable.

The 12 studies reviewed came from 5 countries and were published from 2012‐25. Over half of the studies were published in the last 5 years (2020‐2025) [50-56]. They included 3 single case studies [53,57,58], 2 studies using quasi-experimental approaches [52,59], 1 randomized controlled trial [60], 1 correlational study [61], 1 exploratory observational study [54], 3 retrospective longitudinal studies [50,55,56], and 1 qualitative study [51]. Furthermore, 3 publications examined acute care settings [52,57,61], 6 examined community care settings [50,54,55,58-60], and 3 examined long-term care settings [51,53,56].

The study participants included groups of older adults with mean ages ranging from 78.8 to 84 years old and presenting with mild to advanced dementia. Although 1 study [51] did not involve participants with a confirmed diagnosis of dementia, it was retained due to its focus on the implementation of a behavioral disturbance detection system in long-term care settings, which predominantly serve people with dementia. As such, it provided valuable contextual insights relevant to integrating such technologies into dementia care. Most of the health care professionals included in the studies were nurses [51-54,56,57], followed by physicians [53,56,57], care workers [51,56], a rehabilitation assistant [51,56], an occupational therapist [51,56], and a physiotherapist [51,56]. Table 2 describes the main characteristics of the studies retained.

The studies retained for analysis reported their assessments of specific behavioral and physiological parameters acting as surrogate markers of BPSD. Regarding behavioral parameters, 6 studies assessed motion [50,52,53,55,57,60], 4 assessed activities of daily living [53,55,56,58], 1 assessed sleep efficiency [54], and 1 assessed speech quality [61]. Regarding physiological signs, 5 studies assessed vital and biological signs (blood pressure, heart rate, body temperature, blood oxygenation, weight, and hydration) [50,52,55,59,60]. One study measured electrodermal activity [52], while another study examined patients’ levels of cytokines, such as interleukin-6 and interleukin-10 [54]. One study examined environmental factors associated with BPSD, such as indoor light levels and ambient temperature [50].

Furthermore, 2 studies focused on detecting the 3 specific BPSD, that is, agitation, irritation, and aggression [59,60]; 3 studies examined agitation alone [50,55,56], while another concentrated on detecting agitation and aggression [52]. In addition, 1 study investigated apathy as a distinct form of BPSD [61], and another concentrated on sleep efficacy [54].

Regarding the use of specific scales for detecting and measuring BPSD, 4 studies used the Neuropsychiatric Inventory [50,52,54,61], and another combined the Neuropsychiatric Inventory with the Apathy Inventory [61].

One study indicated that biological parameters, including blood pressure, blood oxygen, heart rate, body temperature, and hydration, were the most significant markers for detecting agitation, irritability, and aggression [60]. Another study identified heart rate and body temperature as the principal markers for verbal aggression, while an accelerometer reading was the most significant marker for physical aggression [52]. One study identified respiratory rate, number of nocturnal awakenings, and the indoor light level as the most important characteristics for identifying agitation [50]. Table 6 summarizes this information.

Only 3 of the studies retained clearly described nurses’ roles in identifying BPSD [51,52,54]. One documented their participation in data collection, specifically documenting episodes of BPSD [52]. Another study described their involvement as participants in a group of health care professionals and the exploration of their perceptions of the potential use of AITs in clinical practice [51]. In research contexts, nurses were part of the research team in 1 study [52] and led the design and implementation of another [54]. None of the retained studies reported on the extent of nurses’ knowledge, skills, and experience in the use of AITs.

This scoping review highlighted how AITs are emerging and being used for the early detection of BPSD, as evidenced by the limited but growing number of publications over the past 5 years (between 2019 and 2025). Despite this limited body of literature, the studies retained were diverse in terms of design, care environment, and health care professional involvement, as well as in terms of their study populations’ characteristics, and this provided a more comprehensive understanding of the various approaches to using AITs in the care of people with dementia.

The studies included in this review encompassed the domains of acute, community, and long-term care and included several types of health professionals, such as physicians, nurses, home care workers, and therapists. Only one of the studies included explored the integration of AITs from an interprofessional perspective, highlighting potential benefits such as improved communication and more proactive care [51]. These findings aligned with previous reviews highlighting AITs’ roles in enabling real-time clinical decision-making and interdisciplinary data sharing [36,38]. However, health care professionals also expressed concerns about how the challenges of implementing AITs might hinder their successful adoption in daily practice, such as workflow disruptions, overreliance on technology, threats to professional identity, costs, and data privacy [51]. These concerns, also reported in previous literature [36,63,64], involve organizational, technological, professional, and cost issues. Identifying these barriers early on is therefore essential to guiding implementation strategies and systems design, thereby enhancing the usability, acceptability, and integration of AITs, particularly in complex interprofessional settings such as dementia care.

Regarding data collection systems and devices, many of the retained studies reported on the combined use of environmental sensors and wearable devices [52,53,55,57,60]. It should be noted that the innovation in these studies does not lie in the use of particular devices or the application of AI, as both have been used before in dementia care settings, particularly to monitor and enhance cognitive function, as well as to track daily activities and physiological parameters [26,28,36,64-66]. Distinctive innovation lies in integrating data collected by these devices with an AI-based analysis specifically aimed at identifying and generating alerts for episodes of BPSD. While similar integrations have been explored in broader smart health monitoring contexts, their targeted use for the early detection of BPSD remains largely underexplored [26,37,38]. These findings are consistent with those reported in previous reviews, which also mentioned mobile apps, text analysis systems, and robots [27,36-38]. For instance, Shaik et al [36] reported on the use of robots capable of monitoring patient behavior. However, none of the studies included in our review used robots specifically for the detection of BPSD, reflecting a broader trend where AITs form parts of psychosocial interventions rather than acting as early detection tools [34].

The variety of connectable devices is particularly interesting, offering health care professionals the flexibility to tailor technologies to care objectives, patients’ preferences, and context-specific needs. Concerning communication systems and data visualization, most of the studies retained used wireless technologies and a secure web portal, reflecting the growing integration of the Internet of Medical Things in health care [53,57-60]. This type of infrastructure enables real-time data transmission and storage, supporting remote monitoring and system interoperability [67]. Using wireless systems facilitates technological integration by reducing the physical constraints that can be particularly relevant for people with dementia, as restrictive or obtrusive devices could cause distress or resistance [68]. However, device acceptability varied across the studies retained, reflecting the mixed findings reported in previous literature [27,36,67]. Acceptability was primarily judged according to ease of use [51,54,60], consistent with previous reviews that also emphasized the importance of simple, intuitive interfaces [27,36]. Regarding device design, 1 study on wearable devices reported their overall feasibility [54]. However, this contrasted with the conclusion by Loveys et al [27], who identified several barriers to acceptance, including discomfort when wearing devices, intrusiveness due to continuous monitoring, and sleep disturbances caused by bed sensors. Another study involving wearable devices similarly reported such inconveniences, particularly a feeling of being constantly monitored [60], in alignment with the barriers described by Loveys et al [27]. Additional concerns included technical issues and forgetting to wear the device [51,60]. These findings are consistent with previous literature [27,36,67] and further reinforce the importance of anticipating such barriers early on in the system design process to improve the user experience and support successful implementation in dementia care settings.

None of the studies included used advanced data storage and sharing systems (such as edge computing) that can improve security and enable the offline functionalities that are important in settings with limited or unreliable internet access, such as in home care or remote regions. While data security remains a major concern in the Internet of Medical Things, AI offers promising support. As Messinis et al [69] stated, machine and deep learning techniques can enhance cybersecurity. However, in the studies reviewed, AI was primarily used for data analysis in research contexts rather than being fully integrated into clinical practice.

Most of the studies retained used classic machine learning to classify or detect BPSD, training models on labeled data to identify predefined behaviors [50,52-55,58,61]. This reflects a broader trend in early-stage research, where annotated datasets are key for model development and validation [35,36].

While some of the studies retained defined abnormal behaviors as deviations from individual baselines, alerts for the occurrence of BPSD were not systematically triggered at fixed thresholds [53,57-59]. Instead, detection often relied on adaptive methods, such as multivariate pattern recognition or unsupervised learning algorithms that adjusted to individual variations over time. These approaches are particularly well-suited to the heterogeneity and fluctuation of BPSD [13,14] and have the added advantage of requiring few or no labeled data, making them suitable for real-time and continuous monitoring [24,70]. In parallel, some studies used expert validation to verify the accuracy or clinical relevance of alerts, either through retrospective review by clinicians [55,57,60] or the integration of rule-based insights during model development [52,53,59]. One study combined supervised and unsupervised techniques to enhance adaptability to individual patterns and clinical relevance, thus supporting a flexible, person-centered approach [57].

The studies retained for review assessed behavioral and physiological parameters as signs of the BPSD, with most being behavioral parameters, including movement and the activities of daily living [50,52-58,60,61]. Regarding specific BPSD, agitation, irritability, aggression, and apathy were the most frequently investigated [50,52,55,56,59-61], with biological parameters and accelerometer data being the most significant markers for detecting them [52,60]. This particular focus may be explained by the clinical urgency and disruptive nature of these symptoms, which place a significant burden on care staff and often require rapid intervention [5,71,72]. Furthermore, these behaviors tend to generate observable and measurable physiological signals, making them more technically accessible to current AITs. These findings were consistent with previous reviews, one of which also highlighted wandering as a distinct type of BPSD commonly targeted by AITs [35,36]. However, this trend underscores the need to assess how effectively AITs can capture the broader spectrum of BPSD, particularly those that are less externally visible, lack distinct physiological markers, and may manifest more gradually over time, such as anxiety, mood-related symptoms, or apathy.

Overall, the algorithms developed across the retained studies demonstrated a good ability to detect the BPSD targeted. This observation aligned with the findings of other reviews, which report the promising detection or classification accuracy of AITs in dementia care contexts [35,36]. However, some limitations must be considered, as they constrain the generalizability of our findings. These include the small sample sizes used in certain studies and the limited occurrence of behavioral events, which may have affected the robustness of algorithm training. Furthermore, although the diversity of study settings and populations represents a strength of the current body of evidence, the heterogeneity in study contexts and their definitions of abnormal behaviors may have limited their comparability and the broader applicability of our findings.

Although nurses represented the majority of the health care professionals included in the studies retained, their knowledge, skills, and experiences of using AITs to detect the BPSD remain undocumented. Given their central role in detecting and managing BPSD, the lack of insight into how nurses interpret algorithmic outputs, respond to alerts, and integrate AITs into their clinical reasoning raises concerns about the clinical relevance, acceptability, and long-term sustainability of such technologies. Only 2 studies included nurses in their research teams, and only one of those was clearly led by nurse researchers [52,54]. The absence of nursing-specific expertise in the development process may result in technologies that are misaligned with real-world care dynamics, increase the risk of misinterpreting AIT-generated alerts, or inadvertently add to workloads rather than reducing them. These findings appear to contradict the existing literature, which emphasizes nurses’ active involvement in developing and implementing AITs in diverse settings and domains of care, including geriatric care [31,33].

Given the lack of studies examining the efficacy of AITs for detecting the BPSD, recommendations regarding their use remain limited and cannot be generalized to clinical practice. Furthermore, the heterogeneity of devices, data types, and analytical approaches hinders the establishment of standards and limits the development of evidence-based recommendations.

Nevertheless, the proliferation of AITs in clinical and care environments is an emergent phenomenon that cannot be overlooked. To ensure that these technologies are properly understood, safely integrated, and clinically meaningful, it is essential to develop core competencies and critical awareness of AITs at an early stage. In parallel, assessing health care professionals’ readiness to provide feedback for training is equally important as it allows educational initiatives to be tailored to existing knowledge, expectations, and perceived needs. This effort should be grounded in an interprofessional perspective, as the implementation and interpretation of AIT outputs typically involve diverse professional disciplines, including nurses, physicians, and allied health staff. Frameworks, such as the conceptual framework for digitally supported communication, coordination, cooperation, and collaboration model, which emphasizes communication, coordination, cooperation, and collaboration, may provide a useful basis for aligning technological solutions with clinical goals, care contexts, and each profession’s roles and responsibilities [73].

Building on this foundation, several actions are needed to support the effective and ethical integration of AITs into dementia care. Educational institutions should reinforce curricula in digital health literacy, algorithmic reasoning, and AI ethics across health care professions, including training on how to interpret algorithmic outputs and assess system reliability. In clinical settings, interprofessional training (through workshops, simulations, or case reviews) can foster shared understanding and critical reflection on AIT use [63]. Health care institutions should identify clinical champions to liaise with developers, support day-to-day integration, and promote peer learning [74]. Beyond health care and academic institutions, the development of these competencies should be supported by professional and regulatory bodies, including organizations issuing evidence-based practice guidelines, as well as geriatric and psychogeriatric associations, which can help contextualize AIT within ethical and clinical standards. Experts in long-term care can also contribute to preparing position statements and evaluation frameworks. From a research perspective, promoting nurse-led, co-designed research is essential to ensure that technological solutions are aligned with the day-to-day realities of care and person-centered values. Evidence shows that nurse-led research, especially by advanced practice nurses, improves care quality, successful implementation, and health system efficiency [75,76]. These efforts are particularly needed in settings where AITs are already being piloted, such as in long-term care and psychiatric units, to ensure safe, supported, and meaningful deployment from the outset.

Most of the studies retained used classic machine learning techniques, with only 2 exploring advanced methods like deep learning, which offers a greater capacity to model complex, temporal, and heterogeneous data [24,77]. Although some studies combined behavioral and physiological data, only 1 [55] applied deep learning to such multimodal inputs, suggesting that this is an underexplored area of research. The use of deep learning to explore the interactions between internal physiological states and external behavioral manifestations of the BPSD holds promise for enhancing the sensitivity, robustness, and contextual adaptability of detection systems. This is particularly relevant given the fluctuating and multifactorial nature of the BPSD. For instance, a review by Wu et al [78] showed that deep learning–based multimodal emotion recognition models outperformed conventional models by integrating behavioral, vocal, and physiological inputs, enabling a more robust and accurate interpretation of emotional and behavioral states.

However, the application of deep learning in health care raises well-known challenges, including a lack of transparency about analysis and prediction process, the limited interpretability of outputs, and a loss of clinical trust [24,74,79]. One promising strategy to address these concerns is the adoption of explainable AI approaches. These rely on techniques such as local interpretable model-agnostic explanations, which help clarify prediction accuracy, and Deep Learning Important FeaTures, which enable traceability by comparing neuron activations to reference states [24]. Promoting such approaches is essential to ensure that AI-driven decisions are not only technically reliable but also aligned with human values and ethical standards.

Furthermore, the practical value of advanced models depends not only on technical performance but also on feasibility and user acceptance. However, limited attention has been given to clinical and contextual factors, such as comorbidities, medication use, functional status, care environments, or staff ratios, which can all affect the expression and detection of the BPSD [2,79-82]. This reflects the exploratory nature of early-stage studies, which prioritized technical development, algorithmic performance, and system functionality. As previously highlighted, several studies also reported barriers to device acceptability, further underscoring the need for future research to consider issues involving clinical complexity and contextual variability.

In this regard, it is important to explore whether and how advanced methods, such as deep learning, can adapt to such variability and enhance the detection of BPSD. Multisite experimental studies should be conducted to assess the robustness and generalizability of algorithms across diverse care settings. Furthermore, the diversity of technological approaches used to detect BPSD highlights the need for experimental or quasi-experimental comparative studies to determine which AITs offer the most effective and reliable outcomes. Such evidence is critical for guiding clinical decision-making and future technological development based on proven efficacy.

In addition, mixed methods studies incorporating user-centered evaluations (such as perceived usefulness, usability, workflow integration, perceived technical performance, and interprofessional communication) and guided by implementation frameworks may offer valuable insights into how contextual factors shape technical outcomes and clinical integration while helping to anticipate potential barriers to adoption. Finally, longitudinal studies will be essential to assess AITs’ long-term impact on the detection and management of the BPSD, on the quality of life of people with dementia and their informal caregivers, on health care professionals’ workloads, and on overall cost efficiency.

This review had some limitations. The number of relevant publications was relatively limited compared with other reviews on the use of AITs in dementia care [34,36-38], which is probably attributable to AI’s relatively recent integration into the management of the BPSD. During our study screening process, a substantial number of publications referenced the use of AITs to detect dementia and evaluate functional status. However, some studies may have involved the BPSD without using this explicit terminology, which could have resulted in their exclusion during the selection of references. Also, no formal quality appraisal of the studies included was performed, as per standard scoping review methodology. However, eligibility criteria and dual screening helped ensure relevance. Despite addressing several dimensions of this topic, the overall lack of available data limited our exploration of other important contextual factors, such as costs, the availability of AITs, and health care infrastructure. This, too, restricted the scope of our recommendations.

The use of AITs for the early detection of BPSD represents a rapidly emerging field of research with the potential to significantly enhance the quality of dementia care. This scoping review highlighted the diversity of AITs explored across various care settings, reflecting promising new avenues for improving the detection of BPSD. However, their clinical efficacy remains to be demonstrated. Future research should evaluate whether AITs support earlier and more accurate detection of BPSD, reduce symptom severity or duration, and improve the quality of life of people with dementia and their informal caregivers. Studies should also examine AITs’ impacts on clinical decision-making, care coordination, and workload management—across diverse populations and care contexts—to ensure relevance and generalizability.

To support their meaningful integration, nurses must be more actively involved in developing and evaluating these technologies. Their clinical expertise and proximity to patients make them key stakeholders in assessing the applicability of these tools in clinical settings. Their contribution should be strengthened through participatory design approaches, inclusion in pilot implementation studies, and interprofessional collaboration throughout the development cycles of new AITs.

The successful integration of AITs into dementia care will depend not only on technical innovation but also on inclusive, clinical, context-sensitive research strategies that can provide robust evidence of their impact in everyday practice.
