Longitudinal methods for Alzheimer's cognitive status prediction with deep learning

Longitudinal methods for Alzheimer's cognitive status prediction with deep learning

INTRODUCTION

Prediction of amnestic mild cognitive impairment (aMCI) and Alzheimer's disease (AD) using machine learning has primarily focused on short-term predictions spanning 1–3 years. This study aimed to develop a new machine learning technique to extend predictions of cognitive status over 3–10 years from their last visit.

METHODS

We leveraged deep learning to analyze two longitudinal feature sets: (1) neuropsychological data and (2) neuropsychological data with the addition of patient history data. We also introduce two modeling techniques: (1) to separate normalized baseline features and deviations from baseline, and (2) a new linear attention-based imputation method.

RESULTS

We demonstrate (1) our technique achieves high 1vA accuracy, representing 81.65% for Control, 72.87% for aMCI, and 86.52% for AD on a 3- to 10-year horizon, and (2) the new method is more accurate than previously proposed approaches for this time horizon.

DISCUSSION

This work offers a new set of techniques for big-data analysis of longitudinal dementia data.

Highlights

  • Develops a new method for the prediction using deep learning of longitudinally verified amnestic mild cognitive impairment (aMCI) and Alzheimer's disease (AD) using the National Alzheimer's Coordinating Center NACC) database.
  • Demonstrates comparable performance on the 3- to 10-year prediction horizon, which is significantly more challenging to predict than using the previous approach that only used a 1- to 3-year prediction horizon.
  • Highlights that even the prediction of verified 3- to 10-year aMCI that eventually leads to AD is still a challenging task.

期刊介绍: Alzheimer's & Dementia is a peer-reviewed journal that aims to bridge knowledge gaps in dementia research by covering the entire spectrum, from basic science to clinical trials to social and behavioral investigations. It provides a platform for rapid communication of new findings and ideas, optimal translation of research into practical applications, increasing knowledge across diverse disciplines for early detection, diagnosis, and intervention, and identifying promising new research directions. In July 2008, Alzheimer's & Dementia was accepted for indexing by MEDLINE, recognizing its scientific merit and contribution to Alzheimer's research.
