Abstract INTRODUCTION We aimed to investigate associations between common infections and neuroimaging markers of dementia risk (brain volume, hippocampal white matter lesions) across three population‐based studies. METHODS tested serology measures (pathogen serostatus, cumulative burden, continuous antibody responses) outcomes using linear regression, including adjustments for total intracranial volume scanner/clinic information (basic model), age, sex, ethnicity, education, socioeconomic position, alcohol, body mass index, smoking (fully adjusted model). Interactions apolipoprotein E ( APOE ) genotype were tested. Findings meta‐analyzed cohorts N main = 2632; APOE‐interaction 1810). RESULTS Seropositivity John Cunningham virus associated with smaller brain volumes in basic models (β −3.89 mL [−5.81, −1.97], P < 0.05); these largely attenuated fully −1.59 [−3.55, 0.36], 0.11). No other relationships robust multiple testing corrections sensitivity analyses, but several suggestive observed. DISCUSSION did not find clear evidence risk. Some findings warrant replication.
