International Journal of Clinical Case Reports, 2025, Vol.15, No.1, 12-23 http://medscipublisher.com/index.php/ijccr 15 2020). These educational and support programs are crucial for preparing families for the challenges of dementia care and ensuring a coordinated and holistic approach to patient management (Moore and Crawley, 2020). 4 Classic Case Analysis: Care Interventions for Behavioral and Psychological Symptoms 4.1 Non-pharmacological intervention methods Music therapy has been widely studied as a non-pharmacological intervention for managing Behavioral and Psychological Symptoms of Dementia (BPSD). Research indicates that music therapy can significantly reduce symptoms of anxiety and depression in dementia patients. For instance, a systematic review and meta-analysis found that music therapy had moderate effects on anxiety and small effects on behavioral symptoms, with larger effects observed in studies lasting more than three months (Ueda et al., 2013). Another study demonstrated that music therapy significantly reduced symptoms of depression and agitation in nursing home residents with moderate to severe dementia (Ray and Mittelman, 2017). Additionally, a randomized intervention study showed that a preferred music listening group intervention improved the emotional state of nursing home residents, with a large effect size (Pérez-Ros et al., 2019). These findings suggest that music therapy is an effective and promising intervention for alleviating anxiety and depression in dementia patients. 4.2 Environmental adjustment and sense of security creation Adjusting the home environment to create a sense of security can significantly reduce agitation in dementia patients. Research has shown that environmental modifications, such as creating a familiar and comfortable living space, can help manage BPSD. For example, a systematic review highlighted that home-based behavioral management techniques and caregiver-based interventions were effective in reducing severe agitation (Abraha et al., 2017). These interventions often involve making the home environment more predictable and less stimulating, which can help patients feel more secure and less agitated. Additionally, ensuring that the environment is safe and free from potential hazards can further reduce anxiety and agitation, contributing to an overall sense of well-being for dementia patients. 4.3 Behavioral guidance and communication skills Effective communication techniques are crucial for helping dementia patients remain calm and manage BPSD. Caregivers trained in person-centered care and communication skills can significantly impact the well-being of dementia patients. Studies have shown that staff training in communication skills and person-centered care can reduce symptomatic and severe agitation. For instance, caregivers who use clear, simple, and empathetic communication can help patients feel understood and less frustrated. Techniques such as validation therapy, which involves acknowledging and empathizing with the patient's feelings, have also been found to be beneficial (Abraha et al., 2017). By employing these communication strategies, caregivers can create a more supportive and calming environment for dementia patients, thereby reducing agitation and improving their quality of life. 5 Classic Case Analysis: Cognitive Function Care Interventions 5.1 Cognitive stimulation and training Cognitive Stimulation (CS) has been widely recognized as an effective non-pharmacological intervention for dementia patients. Memory cards, as a form of cognitive training, can play a significant role in this context. Studies have shown that CS, which often includes activities like memory card games, can lead to improvements in global cognition and memory functions. For instance, a systematic review and meta-analysis found that CS produced a medium-sized effect on global cognition immediately after the intervention, with significant improvements in memory and activities of daily living (Cafferata et al., 2021). Another review highlighted that cognitive stimulation, including memory card activities, consistently benefits cognitive function in people with mild to moderate dementia (Woods et al., 2012). These findings suggest that memory cards can be a valuable tool in slowing cognitive decline in dementia patients. 5.2 Participation in daily activities Engaging dementia patients in daily activities is crucial for maintaining their cognitive and functional abilities. Structured daily activities can enhance a patient's sense of self-efficacy and overall well-being. A randomized controlled trial demonstrated that a multicomponent intervention, which included practice in Activities of Daily
