Title:
METHOD FOR ASSISTING WITH DIAGNOSIS OF ALZHEIMER'S DISEASE OR MILD COGNITIVE IMPAIRMENT, BIOMARKER, REAGENT KIT, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/107154
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a method for easily assisting with the diagnosis of Alzheimer's disease or mild cognitive impairment, a biomarker, a reagent kit, and a device. The present invention relates to a method for assisting with the diagnosis of Alzheimer's disease, said method including using an amount of phosphatidylserine- and tetraspanin-containing extracellular vesicles as an index to determine whether a subject has Alzheimer's disease. The present invention also relates to a method for assisting with the diagnosis of Alzheimer's disease or mild cognitive impairment, said method including using a ratio of the amount of phosphatidylserine- and tetraspanin-containing extracellular vesicles to the amount of tetraspanin-containing extracellular vesicles as an index to determine whether a subject has Alzheimer's disease or mild cognitive impairment. The present invention further relates to a biomarker, a reagent kit, and a device.
