A large-scale UK cohort study found no strong associations between antibodies against multiple common infections and key Alzheimer’s disease neuropathologies, though possible interactions with APOE ε4 genotype and education warrant further
A Brazilian autopsy study of 2,268 individuals reveals that female sex, APOE ε4 status, and African ancestry jointly influence amyloid pathology. Women showed 65% higher adjusted odds of neuritic plaques, and protective effects against amyl
In vivo awake recordings in transgenic mice show APOE ε4 reduces neuronal excitability in the anterior olfactory nucleus (AON); adult females are more excitable than males (a sex difference lost with aging), while aging amplifies network os
Amygdala tau accumulation in cognitively normal older adults correlates with worsening depressive symptoms, especially in APOE ε4 carriers, highlighting its role in neuropsychiatric changes during aging.
The APOE ε4 allele significantly reduces survival in Parkinson’s disease patients independently of dementia, linked to mitochondrial dysfunction and ER stress in PD models.
This study reveals that the APOE ε4 allele is linked to increased dementia prevalence, cognitive deficits, brain atrophy, and plasma biomarkers of neurodegeneration in older adults in the DRC, emphasizing its critical role in African popula
This cohort study from the Young Finns Study elucidates factors influencing blood-based biomarkers for neurodegenerative diseases, highlighting age, APOE ε4 genotype, kidney function, metabolic parameters, and notable intergenerational asso
Regular walking and lifestyle interventions slow cognitive decline, especially in APOE ε4 carriers at heightened Alzheimer’s risk, with effects pronounced in women. Evidence underscores the value of simple activity and healthy diet for at-r
