Causal effect of household income on Alzheimer's disease risk and mediation by cognitive performance: a bidirectional, two‑sample, two‑stage mendelian randomization study

Aug 2026 · Genome Instability & Disease · Vol 7 · 0 citations · 33 references

TL;DR

Household income exerts a protective causal effect on AD, which is predominantly mediated by cognitive performance, elucidate a key mechanistic pathway linking socioeconomic factors to neurodegenerative disease and highlight cognitive function as a potential interventional target, supporting the integration of socioeconomic considerations into AD prevention strategies.

Investigating the Causal Relationship between Neuroticism and Alzheimer's Disease Using Mendelian Randomization and the Mediating Role of Modifiable Risk Factors

Depression, hypertension, hypertension, and alcohol consumption were identified as significant mediators of the relationship between higher neuroticism and increased AD risk, suggesting that the neuroticism-AD relationship is unlikely to be causal.

Evidence from European ancestry genome-wide association studies and a case-control study suggests several selenoproteins are linked to a decreased risk of Alzheimer's disease

Genetic and clinical evidence is provided that specific selenoproteins are associated with a decreased risk of AD and highlight the potential role of these proteins in AD pathophysiology and suggest their promise as biomarkers or therapeutic targets, warranting further investigation.
