1. Delirium was significantly associated with long-term cognitive decline.
2. Across all studies, delirium groups demonstrated worse cognitive outcomes than control groups.
Evidence Rating Level: 2 (Good)

1. Early-life cognitive enrichment was associated with decreased Alzheimer’s disease pathology and cognitive decline in late-life.
Evidence Rating Level: 2 (Good)
Factors such as educational performance and childhood socioeconomic status impact cognitive decline and Alzheimer’s disease- (AD) related pathology later in life. While these are components of early-life cognitive enrichment (ECLE),...
1. This protein-wide association study found that eight specific proteins were associated with cognitive resilience in older adults, pointing toward targets for novel therapies.
Evidence Rating Level: 2 (Good)
Many primary causes of dementia occur among older adults present without commonly recognized neuropathological signatures. Proteomics can be useful in identifying proteins...
