Nursing is an important part of the strategy of diagnosis and treatment of dementia, especially for patients with moderate to severe dementia whose ability to live in daily life is significantly reduced. Personalized care can benefit people with dementia to varying degrees. To formulate a complete dementia nursing plan, it is necessary to fully evaluate the patients under the guidance of dementia nursing principles. The writing group developed guidelines for dementia care based on the findings of existing evidence-based studies for clinical reference. For the literature evidence level and recommendation strength criteria, please refer to the article "Chinese Guidelines for Dementia and Cognitive Impairment (I): Dementia Diagnosis Process" in the series published in this journal (see pages 577-581 of this journal, Volume 91, Issue 9, 2011).
