Datasets, data analysis methods, and key findings for selected studies in research foci 7 – understanding the relationship between cognition and AD.
Study | Datasets | Primary data analysis methods | Key findings |
---|---|---|---|
Vemuri et al. (68) | Clinical and cognitive assessments, CSF, MRI (98 AD, 192 MCI, 109 HC from ADNI) | Correlation analysis | Cognitive reserve and biomarkers of AD pathology are independent predictors of cognitive performance |
Vemuri et al. (69) | Imaging biomarkers, cognitive reserve variables, global cognition measure (393 healthy subjects with one clinical follow-up from MCSA) | Association analysis, linear mixed model | Cognitive reserve offset the deleterious effect of pathologies of the cognitive trajectories |
Amieva et al (70) | Neuropsychological evaluation from 442 AD subjects with 20 years follow-up (171 low education, 271 high education) from PAQUID cohort | Linear mixed model | Cognitive decline occurred up to 16 years and 7 years before AD for high- educated and low-educated individuals, respectively |
