Epigenetic Biomarkers for Alzheimer's Disease

June 23, 2023 updated by: Timothy Kwok, Chinese University of Hong Kong

Identification of Epigenetic Biomarkers for Alzheimer's Disease in Blood Using Epigenome-wide Analysis

Alzheimer's disease (AD) is a neurodegenerative disorder with no know cure. The pathogenesis of late onset AD (LOAD) is complex and multifactorial in nature, with multiple susceptibility genes and environmental factors at interplay.

The objective of this study is to improve our understanding of the risk factors of LOAD by conducting an epigenome wide study within patients of LOAD contrasted against their cognitively normal siblings.
