Delirium is a strong risk factor for dementia in the oldest-old: A population-based cohort study (2012)
Journal Article
Davis, D. H., Muniz Terrera, G., Keage, H., Rahkonen, T., Oinas, M., Matthews, F. E., …Brayne, C. (2012). Delirium is a strong risk factor for dementia in the oldest-old: A population-based cohort study. Brain, 135(9), 2809-2816. https://doi.org/10.1093/brain/aws190

Recent studies suggest that delirium is associated with risk of dementia and also acceleration of decline in existing dementia. However, previous studies may have been confounded by incomplete ascertainment of cognitive status at baseline. Herein, we...
