[Adaptation and validation of the Spanish version of the Pain Evaluation Scale in patients with advanced dementia: PAINAD-Sp].

Introduction: Pain in elderly people is considered a major concern in nursing home facilities affecting between 49% and 83% of the residents. Progression of Alzheimer's Disease causes more communication difficulties in patients with advanced dementia and therefore more problems to understand even the most simple pain evaluation scales. Identification and implementation of appropriate pain management strategies depends on an adequate pain assessment.
