About

This study is a prospective observational study, which involves a cohort of 2000 all-sex and all-ethnic people aged 60 years and above with permanent residence in Tianma area, SheMountain Town, Songjiang District (suburban area), Shanghai. Demographic information, neuropsychiatric scale, peripheral blood, APOE genotype, brain MRI, speech information, AV45-PET, FDG-PET, Tau-PET, GLP-1R PET, and cholinergic receptor probe (ASEM) PET were collected and analyzed. Follow-up visits were performed twice a year for 4 visits, and neuropsychiatric scales and biological samples were collected at each follow-up visit to construct a diagnostic model for patients with mild cognitive impairment, or Alzheimer's disease, as well as a predictive model for the progression of cognitive impairment.

Full description

This study is a prospective observational study, which involves a cohort of 2000 all-sex and all-ethnic people aged 60 years and above with permanent residence in Tianma area, SheMountain Town, Songjiang District (suburban area), Shanghai. Demographic information, neuropsychiatric scale, peripheral blood serum Aβ40, Aβ42, p-tau 181, 217, urine proteomic analysis, APOE genotype analysis, brain MRI, and speech information were collected and analyzed. After initial screening 20% of patients with clinically confirmed MCI and AD were randomly selected for AV45-PET, FDG-PET, Tau-PET, GLP-1R PET, and cholinergic receptor probe (ASEM) PET. Follow-up visits were performed twice a year for 4 visits, and neuropsychiatric scales and biological samples were collected at each follow-up visit to construct a diagnostic model for patients with mild cognitive impairment, or Alzheimer's disease, as well as a predictive model for the progression of cognitive impairment.
