Abstract

Quantitatively measuring the progress of cognitive decline to clarify Mild Cognitive Impairment (MCI) patient has received significant attention in the field of Computer Vision for Medical Imaging. Recent studies have shown promising results for an automated system to estimate various cognitive assessment scores. However, previous models are implemented in such manner that the model accurately estimates scores based on neuroanatomical visual features and measurements that are manually crafted from the original imaging modality during the preprocessing stage. To the best of our knowledge, there are no known estimators that use raw 3D voxel image as an input. For a deeper understanding of early stages of dementia, we provide the basis of an interpretable deep learning model, by implementing a basic 3D Convolutional Neural Network (CNN) model that accurately estimates the Alzheimer's Disease Assessment Scale (ADAS) scores. Based on 10-fold cross validation, our estimation model has achieved correlation of 0.51. For the next action, we would refine the model architecture and generate visual interpretations for evaluation.
