Background/Objectives: This systematic and bibliographic review examines publications in the field of dementia and video game research from 2004 to 2023. The main objective is to assess developments and trends in video game technology for dementia care and detection. Methods: The PubMed database was the primary source for publications. PRISMA guidelines were applied to structure this review. Ten variables were defined, investigated, and split into three main categories: bibliographic, medical, and technical. Results: The results were synthesized using a quantitative approach to reduce bias through interpretation. Of 209 initial results, 77 publications have been included in the investigation. More studies focus on rehabilitation over assessment and detection of dementia. Clinical trials are typically conducted with limited participants. The most populated trials rarely enrol over 300 subjects. On average, around 38 subjects were enrolled in the trials. These studies are commonly supervised by a trainer or technology specialist, suggesting a technology gap in familiarity in the trial demographic. Conclusions: Most interventions assessed were custom-designed applications with a specific outcome, focusing on physical activity and cognitive exercises. As the first of its kind, this publication focuses on the technical aspects of applied technologies and development methods. Using video games to treat and detect patients with cognitive impairments like dementia can benefit healthcare professionals, caretakers, and patients.

Background/Objectives: Home care plays a crucial role in contemporary healthcare systems, particularly in the long-term care of people with chronic and progressive illnesses. Family caregivers often experience substantial physical, emotional, and organizational burden. Telemedicine and digital health applications have the potential to support home care by improving health monitoring, communication, and care coordination. However, their use among family caregivers remains inconsistent, and little is known about how organizational support structures such as telemedicine centers influence acceptance and everyday use. This study aims to examine the benefits of telemedicine in home care and to evaluate the role of telemedicine centers as supportive infrastructures for family caregivers. Methods: A mixed-methods design was applied. Quantitative data were collected through an online survey of 58 family caregivers to assess the use of telemedicine and digital health applications, perceived benefits, barriers, and support needs. This was complemented by an in-depth qualitative case study exploring everyday caregiving experiences with telemedicine technologies and telemedicine center support. A systematic literature review informed the theoretical framework and the development of the empirical instruments. Results: Most respondents reported not using telemedicine or digital health applications in home care. Among users, telemedicine was associated with perceived improvements in quality of care, particularly through enhanced health monitoring, improved communication with healthcare professionals, and increased feelings of safety and control. Key barriers to adoption included technical complexity, data protection concerns, and limited digital literacy. Both quantitative findings and the qualitative case study highlighted the importance of structured support. Telemedicine centers were perceived as highly beneficial, providing technical assistance, training, coordination, and ongoing guidance that facilitated technology acceptance and sustained use. Conclusions: Telemedicine and digital health applications can meaningfully support home care and reduce caregiver burden when they are embedded in supportive socio-technical structures. Telemedicine centers can function as central points of contact that enhance usability, trust, and continuity of care. The findings suggest that successful implementation of telemedicine in home care requires not only technological solutions but also accessible organizational support and targeted training for family caregivers.

Background: This review investigates the use of virtual and augmented reality games in dementia care. It provides an insight into the last 13 years of research, including the earliest publications on this topic, and takes a systematic and bibliographic approach. Methods: We sourced research publications from three different scientific databases (PubMed, Scopus, and APA PsycInfo) for this publication. We chose the PRISMA approach and categorized the studies according to the publisher. A set of 12 variables was defined across three categories (bibliographic, medical, and technical). Results: Of the 389 identified articles, 36 met the inclusion and exclusion criteria. After a phase of pilot studies mainly being conducted, the number of publications increased by four times but decreased again in 2023. Dominating were pilot and feasibility studies; 8 out of the 36 trials were RCTs. The median trial population was 24, and the protocols were performed for an average of 10 weeks, with two 40-min sessions a week. Simulator sickness was reported but not by the majority of participants. A total of 59% of the studies used fully immersive 3D-VR systems. We identified only three publications that provided high immersion quality. These findings indicate the positive effects of using virtual and augmented reality systems on participants’ cognitive function and mood. Conclusions: This publication focuses on the technical aspects of the applied technologies and immersion levels of the patients. Using augmented and virtual reality methods to improve the quality of life and physical interaction of dementia patients shows the potential to enhance cognitive functioning in this population, but further investigation and multicenter RCTs are needed. There are strong indications that this research branch has high potential to benefit both caretakers and patients.

Background/Objectives: The digitization of care opens up new opportunities to support family caregivers, who play a key role in home care. While telemedicine applications have already shown initial relief effects, AI-supported chatbots are increasingly coming into focus as an innovative form of digital support. The aim of this study was to build on an earlier study on the integration of telemedicine into home care and to conduct a complementary study on AI-based chatbots to analyze their acceptance, perceived benefits, and potential barriers from the perspective of family caregivers. Methods: The study comprises two consecutive online surveys with a total of n = 62 family caregivers. The first study assessed the use and acceptance of telemedicine systems; the second complementary survey examined attitudes toward AI-supported chatbots. Both questionnaires were developed based on a systematic literature review and in accordance with the Technology Acceptance Model (TAM). The dimensions of user-friendliness, data protection, communication support, emotional relief, and training needs were among those recorded. The data were evaluated using descriptive statistics, including comparative analyses between the two studies. Results: The results show that family caregivers generally have a positive attitude toward digital health solutions, but at the same time identify specific barriers. While technical barriers and privacy concerns dominated the telemedicine study, the AI results place greater emphasis on psychosocial factors. It also became clear that participants assumed that chatbots would be more acceptable if they were designed to be empathetic and dialogue-oriented. A comparison of the two data sets shows that the perceived benefits of digital systems are shifting from functional support to interactive, emotional support. Conclusions: The results suggest that AI-powered chatbots could offer significant added value to family caregivers by combining information sharing, emotional support, and self-reflection. In doing so, they expand the focus of traditional telemedicine to include a communicative and psychosocial dimension. Future research should examine the actual user experience and effectiveness of such systems in longitudinal and qualitative designs. Despite limitations in terms of sample representativeness and hypothetical usage estimates, the study makes an important contribution to the further development of digital care concepts and the ethically responsible integration of AI into home care.

Um die Anspruchshaltung einer flächendeckenden qualitativ hochwertigen Patientenversorgung aufrechtzuerhalten, sollen in Zukunft vermehrt telemedizinische Verfahren eingesetzt werden, beispielsweise in der Betreuung stationärer Pflegeeinrichtungen. Auch der Kontakt zwischen Arzt und Patient kann mithilfe der elektronischen Visite realisiert werden. Mit Hilfe regionaler Pilotprojekte sind genaue Konzepte für die Durchführung elektronischer Visiten auszuarbeiten. Durch den vermehrten, professionellen Einsatz der neuen Technologien im Bereich der Pflege soll eine effizientere und schnellere Versorgung erreicht werden. Hemmungen aus Sicht des Anwenders können durch realistische Bewertungen der elektronischen Visiten minimiert werden. Die Patientensicherheit aber muss trotz der gesellschaftlichen Herausforderungen bestehen bleiben.

Background/Objectives: Family members who provide care play a central but often underestimated role in the healthcare system and are frequently exposed to considerable physical, emotional, and social stress. To better understand and support their needs, a structured self-assessment tool (SSA-PA) was developed. This development addresses the current lack of practical, validated instruments that enable caregivers to systematically reflect on their own stress levels and resources, which is becoming increasingly important in view of the growing demand for care and the risk of caregiver burnout. This tool aims to promote self-reflection, identify individual stresses and resources, and enable more targeted support for family caregivers. Methods: The development process (September–December 2024) followed a multi-phase design that integrated theoretical foundations from nursing, health, and psychology, in particular Orem’s theory of self-care deficit, Lazarus and Folkman’s stress and coping model, and Engel’s biopsychosocial model. Four core dimensions were defined: (1) health and self-care, (2) burden and stress, (3) support and resources, and (4) satisfaction and quality of life. The final tool comprises 37 items (mostly 5-point Likert scales), supplemented by multiple-choice and open-ended questions. Content validity was ensured through expert review and testing with nine family caregivers. Internal consistency was assessed using Cronbach’s alpha (α = 0.998), indicating very high reliability, although possible item redundancies were identified. The evaluation took place in January 2025 with 33 family caregivers to assess user-friendliness, relevance, and perceived usefulness. Results: The majority of participants rated the tool as user-friendly and clearly structured. Around 80% reported a high level of comprehensibility, and over half stated that the tool provided new insights into their own health and care burden. Qualitative feedback highlighted the value of the tool for self-reflection and motivation to seek external support. Suggestions for improvement included shorter item formulations, improved visual feedback (e.g., progress bars or charts), and expanded question areas on financial burdens and digital support options. Conclusions: The SSA-PA is a theoretically grounded and user-centered tool for assessing and reflecting on the situation of family caregivers. It not only enables systematic self-assessments but also promotes awareness and proactive coping strategies. Future research should focus on conducting factor analyses to further validate the construct, testing the tool in larger samples, and exploring its integration into structured care consultations to improve the quality of home care.
