  • Must be able to speak Mandarin fluently.
  • Willing to undergo multiple 3T MRI scans and at least two PET scans.
  • Agree to collect blood for genomic analysis (including GWAS sequencing and other analyses), AD risk and protective genes such as apolipoprotein E (APOE), klotho, etc., and biological sample storage.
  • Agree to collect blood for biomarker detection.
  • Agree to share genomic data and biomarker samples.

Exclusion

  • MRI brain scan screening reveals infection, infarction or other focal lesions or multiple lacunes or lacunes in key memory structures.
  • Any volunteers who do not meet the MRI scan requirements, including having a cardiac pacemaker, eyes, skin or metal fragments or foreign bodies in the body.
  • Severe depression, bipolar affective disorder described in DSM-IV in the past year.
  • Psychotic features, agitation or behavioral problems that may lead to difficulty complying with the protocol content in the past 3 months.
  • Currently using medication to treat obsessive-compulsive disorder or attention deficit disorder.
  • History of schizophrenia (meeting DSM-IV criteria).
  • History of alcohol or drug abuse or dependence within the past 2 years (metting DSM-IV criteria).
  • Any major systemic disease or unstable physical condition that may make longitudinal research difficult.
  • Clinically significant abnormalities of B12 or TFTs may interfere with the study, low B12 will be excluded.
  • Currently using certain psychoactive medications (e.g., certain antidepressants, neuro-depressants, chronic anxiolytics, or sedative-hypnotics). Currently using warfarin or other anticoagulants such as dabigatran, rivaroxaban, and apixaban (except lumbar puncture).
