About this trial
Dementia is a syndrome characterized by progressive global cognitive impairment that impairs occupational, family, or social functioning. It detrimentally affects personal health and quality of life, imposing significant medical economy, social and psychological burden on the countries and the patients' family. The internationally renowned dementia cohort includes the DIAN that focused on genetics studies, the ADNI cohort featuring imaging and the FINGERS cohort focused on risk factor intervention, etc. Establishing standardized and shared longitudinal follow-up dementia cohorts and clinical database is an essential challenge for constructing dementia cohort in China. Moreover, there is a lack of large-scale prospective longitudinal follow-up cohorts within the Chinese population that cover subjective cognitive decline (SCD) to explore biomarkers with diagnostic and early warning value for different kinds of dementia and pre-dementia stages. The study will rely on the dementia cohort based on Chinese population to explore the biological phenotype characteristics of the pre-dementia stage and different dementia subtypes, and observe the dynamic change rules of the dementia cohort vertically, so as to foster early intervention and improve prognosis for individuals with dementia.

Trial groups
Trial outcomes
Primary outcomes
Rate of change in global cognition as measured by Clinical Dementia Rating (CDR).
Assess statistically significant difference in score between dementia-P and dementia-S using the neuropsychological scales CDR. CDR, a multidimensional scale for dementia severity, which scored 0-3, with higher scores indicating worse functioning.
Secondary outcomes
Rate of change in global cognition as measured by Mini-Mental State Examination (MMSE)
Assess statistically significant difference in score between dementia-P and dementia-S using the neuropsychological scales MMSE. MMSE scores range from 0-30, with higher scores representing better cognitive function.
Rate of change in global cognition as measured by Montreal Cognitive Assessment (MoCA)
Assess statistically significant difference in score between dementia-P and dementia-S using the neuropsychological scales MoCA. MoCA scores range from 0-30, with higher scores representing better cognitive function.
Rate of change in the severity of cognitive impairment as assessed by Alzheimer's Disease Assessment Scale-Cognitive section (ADAS-cog).
Assess statistically significant difference in score between dementia-P and dementia-S using the neuropsychological scales ADAS-cog. ADAS-cog scores range from 0-70, with higher scores indicating better global cognitive function.
Rate of change in memory function as assessed by World Health Organization-University of California, Los Angeles, auditory verbal learning test (WHO-UCLA AVLT).
Assess statistically significant difference in score between dementia-P and dementia-S using the neuropsychological scales like WHO-UCLA AVLT. WHO-UCLA AVLT scores depend on the number of correct words, which ranges from 0-15, with higher scores representing better memory function.
