The aim of this study was to determine whether self-reported or informant-reported SCCs best predict progression to mild cognitive impairment (MCI) and/or dementia. Methods: We reviewed prospective longitudinal studies of Cognitively Unimpaired (CU) older adults with self-reported and informant-reported SCCs at baseline, assessed by questions or questionnaires that considered the transition to MCI and/or dementia. A random-effects meta-analysis was performed to obtain pooled estimates and 95% CIs. Results: Both self-reported and informant-reported SCCs are associated with an elevated risk of transition from CU to MCI and/or dementia. The association appears stronger and more robust for informant-reported data [1.38, with a 95% CI of 1.16 –1.64, p < 0.001] than for self-reported data [1.27 (95% CI 1.06 – 1.534, p = 0.011].ConclusionsOur results suggest that corroborated information from one informant could provide important details for distinguishing between normal aging and clinical states PB Elsevier YR 2022 FD 2022 LK http://hdl.handle.net/10347/29479 UL http://hdl.handle.net/10347/29479 LA eng NO Ageing Research Reviews 82 (2022) 101772 NO This work was supported though FEDER founds by the Spanish National Research Agency (Spanish 'Ministry of Science, Innovation and Universities) (Project Ref.
