Serum Lipidome as an Early Peripheral Indicator in Familial Alzheimers Disease

Gloria Patricia Cardona‐Gómez, Ivan Daniel Salomon-Cruz, Laura Alejandra Lozano-Trujillo…·Estela Área-Gómez

The paper identifies a serum lipidomic signature in asymptomatic Alzheimer's disease mutation carriers that differentiates them from non-carriers and correlates with dementia risk factors.
