Individuals with dementia have communication limitations resulting from cognitive impairments that define the syndrome. Whereas there are numerous cognitive assessments for individuals with dementia, there are far fewer communication assessments. The Profiling Communication Ability in Dementia (P-CAD) was developed to address this gap. The purpose of the study was to answer the following research questions: 1) What is the validity and reliability of the P-CAD? 2) Is it sensitive to change over time in the cognitive communication ability of the person with dementia?
