Biomarker composition for diagnosis of Mild cognitive impairment using nasal samples and method of diagnosing Mild cognitive impairment using the same

摘要

The present invention relates to a composition for diagnosing mild cognitive impairment for non-invasive in vitro diagnosis and a kit comprising the same, and more specifically, to a non-invasive biological sample, an isolated runny nose sample, S100A9 protein or a gene encoding the same for diagnosing mild cognitive impairment A biomarker composition, a kit for diagnosing mild cognitive impairment including the same, and a method of providing information necessary for diagnosing mild cognitive impairment. The biomarker composition and kit according to the present invention can diagnose mild cognitive impairment with only a small amount of runny nose, so it is very excellent in terms of convenience and economy, and it can identify patients with Alzheimer's disease and patients with mild cognitive impairment. It can be effectively used to make a treatment plan for a disorder.
