WebApr 6, 2024 · When the AD group was stratified into MCI-AD and mild AD dementia, we found that C1q levels tended to be higher in MCI due to AD (p = 0.07) compared to controls (Figure 5B). Overall, higher levels of C1q in AD are in line with our proteomics data from Cohort 1, where this protein was also found to be increased in CSF EVs. Webdetect preclinical AD (see Imaging in Differential Diagnosis of Dementia and Biomarkers in Alzheimer’s Disease in this issue). The neuropathology of AD begins many years before symptoms appear and as much as 30 years before demen-tia occurs.10 In the preclinical AD stage, β amyloid can be detected in the CSF and on amyloid positron emission
