Nonverbal Communication in Dementia Care: A Review of Its Application and Influence on Patients’ Quality of Life
Abstract
Objective: To review the mechanism, application scenarios, and existing problems of nonverbal communication in improving dementia patients’ quality of life and to provide a reference for nursing practice and future research. Methods: Literature related to “dementia”, “non-verbal communication”, and “quality of life” published from 202 to 2024 was searched through CNKI, Wanfang, PubMed, etc., are included in studies on clinical nursing, non-pharmacological interventions, and communication strategies for narrative integration. Results: Existing studies show that nonverbal communication elements (eyes, gestures, touch, spatial distance, intonation, and environmental cues) can improve patients’ subjective security and quality of life through cognitive activation, emotion regulation, memory arousal, behavioral stability, self-care promotion, and social participation. Application needs and implementation priorities differ across hospitals, elderly care institutions, and home care. Current evidence is limited by small sample sizes, high heterogeneity, and a lack of standardized assessment tools and high-quality randomized controlled trials. Conclusion: Nonverbal communication is a key nursing strategy to compensate for language barriers and improve quality of life in dementia care. In the future, it is necessary to establish a unified evaluation system, conduct high-quality multi-center research, and explore AI’s potential to support objective quantification and individualized intervention of nonverbal signals.
