- Dementia Risk Lower With Anti-Inflammatory Diet Even With Alzheimer's Biomarkers
A longitudinal study in Sweden found that people with Alzheimer's disease biomarkers who followed a less inflammatory diet had a lower risk of developing dementia over 8 years. The anti-inflammatory dietary pattern was associated with reduced dementia risk despite the presence of Alzheimer's biomarkers.
- Racial diversity in higher education is associated with higher student salaries

- Loneliness in older adults can often lead to memory impairment
A longitudinal study published in Aging & Mental Health found that older adults experiencing higher levels of loneliness scored lower on memory tests, though their memory decline rate over six years matched non-lonely peers. Researchers suggest loneliness may influence initial memory performance more than long-term cognitive decline.
- There’s New Evidence for How Loneliness Affects Memory in Old Age
A longitudinal study reveals that loneliness in old age is more strongly associated with lapses in immediate and delayed recall than with the overall speed of cognitive decline. The findings highlight specific memory impacts linked to social isolation in aging populations.
