Four Common Beliefs About Patient Memory Evaluations: Who Has Them and What Modifies Them?

Understanding public beliefs about patients at memory centers may inform efforts to promote early diagnosis and guide clinical discussions of Alzheimer's disease (AD). Adults (N=3,527) read a vignette describing a fictional person at a memory center and rated the person's condition as a mental illness, part of typical aging, and psychological or biological origins. Vignettes varied by AD biomarker result, symptom stage, and treatment availability. Participants most strongly believed that the condition was part of typical aging and biological in origin, though beliefs varied across subgroups. Black and Asian participants reported stronger beliefs than White participants that the condition was a mental illness (β=0.39, P<0.001) and psychological (β=0.46, P<0.001). Men reported stronger beliefs that the condition was a mental illness (β=0.19, P<0.001), psychological (β=0.14, P<0.001), and part of typical aging (β=-0.08, P=0.04). Biomarker positivity heightened biological and lowered psychological attributions (all P<0.05). The findings offer specific insights to guide intervention.
