Background: Alzheimer's disease (AD) is a devastating neurodegenerative disorder with few therapies to treat, mitigate or prevent its onset. Understanding of this disease is predominantly based on research in non-Hispanic Whites (NHW) although AD disproportionately affects African Americans (AA) and Latin Americans (LA), underrepresented in AD research. To address this knowledge gap, the Accelerating Medicine Partnership for Alzheimer's Disease (AMP-AD) Diversity Working Group was launched to generate multi-omics data from post-mortem brain tissue from donors of predominantly AA and LA descent.

Background: Severe systemic infections can trigger cognitive decline, but the underlying mechanisms and their impact on the manifestation and progression of Alzheimer's disease and other neurodegenerative diseases are poorly understood. The current COVID-19 pandemic has brought a surge of severe viral illness and highlights the importance of understanding the impact of acute infections on cognition and the manifestation of neurodegenerative disease in survivors. A wealth of observational and clinical data suggests major short- and long-term effects of severe infections on cognition, but detailed and systematic analyses of neuropathological changes after acute infections are scarce.
View Article and Find Full Text PDFBackground: The aging and dementia field has long been interested in understanding disease heterogeneity, subtypes, and progression. Work has progressed from clinical, to neuroimaging to biomedical devices to neuropathological data, and now brain and blood omic data.
Method: The AMP-AD consortium generated and/or annotated genomic, epigenomic, transcriptomic, proteomic, and metabolomic data from brain and/or blood from thousands of study participants and patients across the 8 teams.

Background: The intricate and heterogeneous phenotypes associated with neuropsychiatric symptoms (NPSs) encumber exploration of their role in the neuropathology and underlying biological mechanisms of Alzheimer's disease (AD) continuum.
Method: An individual-level Regional Radiomics Similarity Network (R2SN) for 487 patients with AD continuum (376 with NPSs vs. 111 without NPSs) were developed to find the R2SN connections associated with NPSs and refine the subtypes of NPS in the AD continuum.
