Abstract | BACKGROUND: METHODS: A systematic search with comparison of NfL level between individuals with MCI and healthy controls were retrieved from PubMed, Embase, and Web of Science. The standard mean difference and 95% confidence interval were calculated using the random-effect model to analyze the differentiation of NfL between patients and controls. RESULTS: A total of 7 studies were included. NfL was higher in 676 MCI than 504 healthy controls. Subgroup analysis according to sample type indicated that differentiation of NfL in CSF between patients with MCI and controls showed significant results but in blood. Moreover, the NfL increasing still existed when the NfL expression level was detected by enzyme-linked immunosorbent assay but single molecule array assay. However, no difference of NfL in MCI between Caucasian and Asian was found. CONCLUSIONS: NfL expression level in CSF was increased in MCI individuals, which indicated that NfL in CSF could be a potential biomarker of MCI.
