Original description
Mild cognitive impairment (MCI) and neurocognitive disorder such as Alzheimer's disease (AD) and Vascular dementia (VaD) have become common diseases in the elderly. The burden of dementia is rising in China, with major medical, social and economic impacts. To address this important public health problem, cohort study on elderly cognitive disorders should be carry out. The methods of early prevention, early diagnosis and early treatment the cognitive disorders in elderly should be found to reduce the burden of the social and economic issue due to dementia. At present, the international corresponding guidelines have taken gene and brain imaging biomarkers as important indicators of dementia pathogenesis research, accurate diagnosis and targeted intervention. The study will construct a prospective cohort to establish database that provide not only comprehensive epidemiological data on the MCI and neurocognitive disorder in ageing people, but also complete the construction of biological samples bank and clinical diagnosis and treatment information database. Using the database, the study will identify the conversion rates from MCI to dementia and risk factors for the progression from MCI to dementia or AD. The study will also apply and develop brain structural and pathological imaging technology to support precision diagnosis of senile cognitive disorders. The study have goals to identify and validate imaging and blood/CSF biomarkers for the early detection and tracking of cognitive disorders.Read full original descriptionShow less
