Older adults with cognitive impairment often face difficulties with comprehension and communication, which can impact other cognitive processes such as decision-making. This scoping review investigates how visual methods can support older adults with cognitive impairment. The review involved querying four databases. From these databases, eleven articles fit inclusion criteria. This paper examines the purposes, use contexts, types, and effectiveness of the visual methods described in each study. The two major use contexts were elicitation of thoughts, feelings, and preferences in everyday life and health/healthcare related uses. Studies that used visual methods for eliciting preferences generally employed static visualizations. Health-related contexts employed more complex and interactive visualizations. Three studies used visual tools to support older adults in understanding; six, communication; and three, decision-making. None addressed all three outcomes of interest. This study provides recommendations and future directions for visual communication research with older adults with cognitive impairment.
