Abstrakt: Alzheimer's disease (AD) is the most common form of dementia worldwide and represents a growing socio-economical issue. To date, no reliable diagnosis can be obtained at an early-stage of the disease, though it is now recognized that the aggregation of the amyloid ß (Aß) peptide is responsible for the onset of the disease. Recent studies have shown that soluble amyloid oligomers present in the physiological fluids were the most neurotoxic species and correlated best with the first signs of cognitive decline, which makes them good biomarkers in the development of a diagnostic tool.
