Abstract
INTRODUCTION: Menopausal hormone therapy (MHT), along with the apolipoprotein E (APOE) ε4 allele, has been suggested as a possible risk factor for Alzheimer’s disease (AD). However, the relationship between MHT and cerebrospinal fluid (CSF) biomarkers is unknown: we investigated this association, and whether APOE4 carrier status moderates it. METHODS: In an observational study of 134 cognitively unimpaired female participants (Mage=66.1; SD=6.3), we examined whether MHT use alone or in interaction with APOE4 carrier status was associated with CSF levels of ptau, Aβ40, Aβ42, p-tau/Aβ42 and Aβ42/40 ratios. RESULTS: Significant interactions were found between APOE4 and MHT use for CSF biomarkers. APOE4 carriers who were MHT users showed worse levels of CSF p-tau/Aβ42 and Aβ42/40 ratios, than all other users and non-users. DISCUSSION: The presence of both APOE4 and MHT may be associated with elevated amyloid deposition and AD pathology in this sample of participants who demonstrated high familial AD risk.
