简要总结
The purpose of our study is to investigate CSF and blood biomarkers among the subjects with mild cognitive impairment (MCI) and Alzheimer's disease (AD) as well as normal controls.
详细描述
Alzheimer's disease is the most prevalent cause of dementia. A biomarker is a variable that are measured in vivo and indicate specific features of disease related molecular mechanisms and pathologic changes, including amyloid processing and aggregation, tau hyperphosphorylation, accumulation of neurofibrillary tangles, synaptic dysfunction, neurodegeneration, and loss of brain tissue.
We examine serum oligomeric beta-amyloid 42 and CSF monomeric beta-amyloid 42, total tau and phosphorylated tau, as well as PiB-PET, FDG-PET and brain MRI in 90 participants (30 normal controls, 30 patients with mild cognitive impairment, 30 patients with Alzheimer's disease).
