Objective: Establish cohort of patients with mild cognitive impairment (MCI) in order to identify the risk factors and validation of neuropsychological tests for early detection of Alzheimer disease.
Methods: Four hundred participants with MCI were enrolled in at Huashan Hospital in Shanghai, China. All patients will be followed once annually for 3years. The primary endpoint is the time of conversion from diagnosis of MCI to Alzheimer disease (AD).
Results: of the 400 subjects, 170 (42.5%) were male, and the average mean age and education was 68.7 (Standard Deviation, SD: 8.2, 45- 90 years old) and 12 years (SD: 3.1), respectively. At baseline age, education and being single influenced MMSE, ADAS-cog13 and most domains of cognition.
Conclusions: Baseline characteristics of the Shanghai MCI cohort study indicate the participants were younger, less educated and had a moderate gender ratio compared to other studies conducted so far and represent the target population. 3 years later when the cohort will be finished some risk factors Associated with the conversion will be validated and some novel factors will be identified.
