Persons With Cognitive Impairment and Care Partner Motivations and Experiences of Undergoing an Amyloid Scan: A Systematic Review of Qualitative Studies

Abstract

Abstract Background and Objectives Amyloid positron emission tomography scans can enhance the accuracy of dementia diagnoses. However, the perspectives and experiences of people with cognitive impairment and their care partners undergoing an amyloid scan are less well understood. Therefore, this review aimed to identify and summarize qualitative studies exploring patient and care partner experiences of undergoing an amyloid scan. Research Design and Methods We searched Embase, MEDLINE, and PsychInfo in March 2024. Articles were screened for inclusion by 2 reviewers and critically appraised using the Joanna Briggs Institute Critical Appraisal Tool for Qualitative Studies. Data from the included studies were synthesized using thematic synthesis. Results We identified 10 papers from 6 studies. We identified 4 themes: (1) motivations for undergoing an amyloid scan, (2) experiences of receiving the result, (3) emotional responses to the result, and (4) actions in light of the scan result. Participants reported undergoing the scan to determine the cause of cognitive impairment. They described the information gained from the scan as helpful but struggled to recall the correct terminology or implications of the scan. Emotional responses to the scan varied depending on the scan result. In light of the scan result, the most common action was making advanced plans; however, this was mainly discussed among participants with elevated amyloid. Discussions and Implications Amyloid scans can provide useful and actionable information. However, learning the scan result could be distressing. Future research is needed to balance the potential benefits and harms of amyloid scans.
