A fiber-optic based multiplexed, in-vivo sensor for Alzheimer's disease monitoring and risk stratification Lead Investigator: Shawana Tabassum Institution : E-Mail : stabassum@uttyler.edu Proposal ID : 1660 Proposal Description: The goals of the proposed research are: 1. develop and validate a multiplexed fiber-optic sensor for in-vivo monitoring of multiple biomarkers of dementia in cerebrospinal fluid (CSF). 2. develop a regression model to find the correlation between CSF biomarkers (i.e., correlation of one biomarker in relation to others). 3. develop a classifier to provide risk stratification of Alzheimer's based on CSF biomarker levels. The expected outcomes are: 1. a multiplexed fiber-optic sensor that will detect multiple biomarkers in cerebrospinal fluid (CSF) in a single assay. 2. a regression model that will enhance our understanding of the pathogenesis of Alzheimer's and help clinicians identify the most useful biomarkers for early diagnosis and prognosis of Alzheimer's 3. a machine learning model that will classify Alzheimer's patients according to risk scores.
