Brain Aging Related Conditions Clinical Trial
Official title:
A Prospective Cohort Study on the Associations of Endocrine Glucose & Lipids With Brain Aging-related Conditions in Chinese Men and Women
With aging, brain aging leads to a general decline in cognitive ability, and the prevalence of neurodegenerative diseases such as Alzheimer's disease (AD) and Parkinson's disease (PD) increases. The prevalence of abnormal glucose and lipid metabolism also increased with age. The imbalance of glucose and lipid metabolism is closely related to brain aging related conditions and diseases, and the relationship between glucose and lipid metabolism and brain aging has not been fully elucidated. Phase 1: Baseline investigation (community-based survey) Aims: To investigate whether glucose and lipids are the risk factors for brain aging-related conditions, such as mild cognitive impairment. Subjects and Methods: A community-based survey will be carried out in 10000 natural population aged >=50 years selected from 10-12 communities stratified according to geographic regions (Ciyao, Huafeng, Dongzhuang, Heshan, Geshi, Jiangji, Gangcheng, Fushan, Dongshu, Sidian, Baxianqiao, and Xiangyin, etc) in Ningyang County, Taian City, Shandong Province. A comprehensive examination including questionnaire (including the MMSE and ADL evaluation for the participants), anthropometric measurements, biochemical analysis will be performed in each study participant. In particular, the investigators randomly selected 1000-2000 participants performing MRI of the brain to evaluate the brain aging related conditions. Phase 2: Cohort follow-up Aims : To examine glucose and lipids metabolism levels and their changes that modify the risk of brain aging-related conditions. Subjects and Methods: To recruit and follow all 10000 participants for at least 3-5 years. In particular, all 1000-2000 participants with the baseline MRI examination will perform the MRI examination again for the follow-up.
