Hearing aid use was associated with a modestly lower risk of probable dementia overall (Hazard Ratios, HR, 0.91), but the association was confined to participants reporting improvements in hearing (HR 0.86), with no apparent benefit among those reporting poor improvement in hearing (HR 0.98).

Neighborhood disadvantage in later life is associated with poorer cognition and increased vulnerability to dementia.
-
Compared to those in rural areas, participants who resided in urban areas during young adulthood had lower late midlife ADI (β = -0.85, p < .05), and better executive function (β = 0.19), processing speed (β = 0.24), and verbal fluency (β = 0.30) (ps < .05) in older adulthood.
-
Central-northern rural communities exhibited the most pronounced high-high spatial clustering of cognitive impairment (Global Moran's I = 0.17, p < 0.001).
-
The MIND diet may buffer the cognitive consequences of cerebrovascular pathology and cortical atrophy in older adults at elevated dementia risk and promote cognitive resilience over general healthy eating guidelines.
-
Our findings suggest that non-economic social deprivation, especially in terms of access to a grocery store, pharmacy, postal office, and bus stop, might be relevant for maintaining cognitive functioning in old age.
-
If a substantial synergetic effect is detected, it may lead to the use of more widespread concurrent physical and cognitive training and the potential development of methods to make concurrent training practical.
-
Cognitive training appears effective in improving cognitive functions and delaying cognitive decline in people at risk of Alzheimer's disease but requires more standardized research for conclusive evidence.

-
Cognitive training shows potential in preventing cognitive decline in individuals at risk for Alzheimer's disease, especially as part of multimodal interventions, though current evidence varies in quality and clarity.

The evidence for cognitive training in preventing cognitive decline in Alzheimer's disease is varied, with some studies indicating cognitive benefits but showing limited impact on functional outcomes or disease progression.

-
IBD is associated with CI and increased dementia risk, with biologics potentially mitigating neuroinflammation-related decline.
-
In this multicenter randomized clinical trial among older adults with family history of dementia and/or self-reported subjective cognitive decline, exercise, IRVR, or both did not result in statistically significant differences in improvements in cognitive function over 24 months.
-
MCI patients showed significantly reduced plasma levels of TGF-β1 and increased TNF-α concentrations compared to other participants.
-

A total of 2,642 participants with a mean age of 64.3 years (95% CI 63.4-65.1, 44% male) were included.
