Abstract: Background:Neurocognitive disorders (NCD) are underdiagnosed in primary care, mainly because of the misunderstanding of benefits associated with timely diagnosis. Objective:The aim of this study was to explore the benefits and risks of diagnosis in a population of general practitioners (GPs), specialized physicians (SPs), other healthcare professionals (HPs), and informal caregivers (ICs). Methods:A questionnaire was submitted to GPs, SPs, HPs. and ICs. It aimed at evaluating benefits and risks related to NCD diagnosis associated with four prototypical clinical cases at different stages: isolated cognitive complaint/mild NCD, major NCD at mild/moderate stage, moderate stage with behavioral and psychotic symptoms, and severe stage. The concepts of early, timely, and personalized diagnosis were evaluated. Results:A total of 719 completed surveys were collected from 183 GPs, 176 SPs, 281 HPs, and 79 ICs. More than 90% of the participants considered initiating a diagnosis as relevant except at the severe stage. Benefits were superior to risks for all groups and all four cases alike (p < 0.001). Benefits were lower according to GPs and higher for SPs than the other groups at the first two stages (p < 0.001). At the moderate stage, there were few differences between groups. At the severe stage, GPs and SPs claimed it was less relevant to carry out a diagnosis than the other groups (p < 0.001). Risks were higher for ICs and lower for SPs (p < 0.001). The best diagnosis concept was the personalized diagnosis. Conclusion:Benefits appeared more relevant than risks with differences according to the stage of the disease and type of respondents.
