Methods: We selected 421 MCI patients from the Alzheimer’s Disease Neuroimaging Initiative (ADNI). We collected their information, including gender, age, years of education, marital status, 18F-florbetapir-PET scan (a radiological test used to detect Aβ deposition in the brain), cerebrospinal fluid (CSF) Aβ, CSF tau protein, CSF p-tau protein, and neuropsychological test scores. Based on their Apolipoprotein E (ApoE) genotype, MCI patients were categorized into ApoE ε4(+) group (n = 202) and ApoE ε4(−) group (n = 219), further subdivided into Aβ(+) and Aβ(−) subgroups based on Aβ status. We compared the differences between corresponding groups using statistical methods and analyzed the factors contributing to these differences. Results: In the MCI patient groups with ApoE ε4(+) and ApoE ε4(−), the age of the Aβ(+) subgroup was significantly higher than that of the Aβ(−) subgroup, with the difference being statistically significant (P β in the Aβ(+) subgroup was lower than those in the Aβ(−) subgroup, while the CSF tau and p-tau were higher, with the differences being statistically significant (P ε4(+) group’s Aβ(+) subgroup performed worse on multiple neuropsychological scales compared to the Aβ(−) subgroup, particularly in memory function scales, with the difference being statistically significant (P β and ApoE ε4 leads to a decline in cognitive functions among MCI patients, with a particularly pronounced impairment in memory.展开更多
