... non-invasive and low cost has intrigued a wide range of interests. To identify individuals with high risk of conversion to AD and apply the research concept of prodromal AD into clinical practice, the utility of various biomarkers for distinguishing prodromal AD is evaluated in this review. Additionally, clinical management focusing on the stage of prodromal AD is summarized in this review for dementia prevention.
