WebINTRODUCTION. In 2016, Alzheimer’s disease (AD) was the 6th leading cause of death in the United States, directly affecting an estimated 5.4 million Americans and incurring $236 billion of total healthcare costs [].Alzheimer’s disease is a neurodegenerative disease characterized by dementia, accumulation of beta-amyloid plaques and tau proteins on … WebOct 1, 2024 · Methods. Genome Research at Fundacio ACE ([email protected]) is a genome-wide study of dementia and its clinical endophenotypes, defined based on AD's clinical certainty and vascular burden.We assessed the impact of known AD loci across endophenotypes to generate loci categories. We incorporated gene coexpression data …
