NCT04804618

Brief Summary

This study intends to adopt standardized and rigorous cross-sectional research, collect biological specimens (including blood, feces, urine, saliva and tongue coating) from eligible subjects, and use liquid chromatography/mass spectrometry (LC-MS/MS) technology to explore early warning indicators of protein in patients with mild cognitive impairment and Alzheimer's disease

    Proteomic expression of urine and saliva in each group will be tested use Protein liquid chromatography/mass spectrometry detection.

    An Average of 1 year

Secondary Outcomes (3)

  • Change of the cognitive function every year

    An Average of 1 year

  • Changes in plasma protein expression profile every year

    An Average of 1 year

  • Variation characteristics of gut microbiome every year

    An Average of 1 year

Study Population

From March 2021 to March 2022,people who finish the cognitive examination at Guangdong Provincial Hospital of Chinese Medicine and the Guangzhou Cadre Health Management Center would be this study population. All the eligible participants will be follow up every year until 2026.

You may qualify if:

  • Older than 55-year-old,male or female.
  • patients meet the diagnosis of mild cognitive impairment (MCI) or Alzheimer's disease(AD) or whose family members were diagnoed with AD
  • Complete self-rating scale for memory impairment (AD-8 scale)
  • Those who agree to participate in clinical research and sign informed consent.

You may not qualify if:

  • Patients with acute cardiovascular and cerebrovascular diseases, acute infections (pneumonia, urinary tract infection, oral infection, digestive tract infection), severe renal dysfunction, and uremia;
  • Pregnant or lactating women;
