This kind of data can also catch small effects that surveys might miss and supports creating personalized care plans using real-time information (Perez-Pozuelo et al., 2020; Song et al., 2021). 7.3 Establish a unified care program and enhance family and community assistance Formulating a clear and scientific sleep care plan is of great significance for achieving stable and effective care results in various regions. Unified steps can make research easier to repeat, results more convenient to compare, and promote experience exchange and sharing among medical institutions (Daniel et al., 2024; Gale et al., 2025). At the same time, these plans should retain a certain degree of flexibility to meet the needs of each patient, but still follow the key principles proven by research. It is equally important to enhance the assistance from families and communities, as dementia care is mostly carried out outside hospitals and at home. Teaching family members some methods to involve them in planning and follow-up work can help maintain a regular sleep schedule and improve the patient's condition (Gale et al., 2025). The projects and resources of the community can also complement the deficiencies of family care, help address problems early, and support a more comprehensive approach to dealing with sleep disturbances in Alzheimer's patients. 8 Concluding Remarks Nurse-guided sleep care can help dementia patients sleep better, reduce sleep troubles and improve overall well-being. Adjusting the environment, adopting simple behavioral methods and providing tailor-made care for patients are now regarded as important parts of comprehensive care for dementia patients in nursing homes and hospitals. Melatonin and cortisol are responsible for regulating the body's clock and stress response, and may be useful signals for measuring the effectiveness of sleep care. Although there is not much research evidence on their changes, improved sleep may be related to more stable melatonin and cortisol patterns, which in turn are associated with the improvement of thinking and behavior in patients with dementia. Using these signals can make the assessment more accurate and also support the formulation of personalized care plans. Scientific nursing is a key part of comprehensive care for dementia. It is patient-centered and meets both physical and emotional needs in a non-pharmaceutical way. To achieve better results, it is necessary for multi-disciplinary teams to collaborate, continuously train personnel, and make adjustments based on the special requirements of dementia care. As research progresses, incorporating sleep care into daily routines is of great significance for enhancing the quality of life and health of this key group.
