Background: Aß oligomers are synaptotoxic and may initiate neurodegeneration in early stages of Alzheimer´s disease (AD). Method: 526 patients and controls from the DELCODE cohort were clinically diagnosed and afterwards neurobiologically classified using the ATN‐system. Aß and Tau oligomers were determined using the sFIDA technology. Result: Within the AD continuum highest oligomer levels in CSF were detected in amyloid positive SCD and MCI. Aß oligomers outnumber in A+T‐ when compared to normal biomarker profile (A‐T‐) or full‐blown AD pathology (A+T+). APOE ε4 was associated with elevated Aß oligomer levels. No differences in Tau oligomers were found. Conclusion: The appearance of Aß oligomers in CSF is an early event within the AD continuum precedeing the maximum of Tau pathology. Targeting Aß oligomers by disease modifying treatment in early disease stages might be crucial and is supposed to have the highest therapeutical potential in AD. [ABSTRACT FROM AUTHOR] |
