Association of APOE ε4/ε4 with fluid biomarkers in patients from the PUMCH dementia cohort.

ABSTRACT:

Background

Apolipoprotein-E (APOE) ε4 is a major genetic risk factor for Alzheimer's disease (AD). Current studies, which were mainly based on the clinical diagnosis rather than biomarkers, come to inconsistent conclusions regarding the associations of APOE ε4 homozygotes (APOE ε4/ε4) and cerebrospinal fluid (CSF) biomarkers of AD. In addition, few studies have explored the associations of APOE ε4/ε4 with plasma biomarkers. Therefore, we aimed to investigate the associations of APOE ε4/ε4 with fluid biomarkers in dementia and biomarker-diagnosed AD.

Methods

A total of 297 patients were enrolled. They were classified into Alzheimer's continuum, AD, and non-AD, according to CSF biomarkers and/or β amyloid PET results. AD was a subgroup of the
