Graph of brain structures grading for early detection of Alzheimer's disease
This work addresses the challenging problem of early Alzheimer's diagnosis for patients, but it appears incremental as it builds on existing biomarker approaches.
The authors tackled early detection of Alzheimer's disease by proposing a novel framework that combines inter-subject similarity and intra-subject variability into a graph of brain structures grading, achieving competitive performance compared to state-of-the-art methods.
Alzheimer's disease is the most common dementia leading to an irreversible neurodegenerative process. To date, subject revealed advanced brain structural alterations when the diagnosis is established. Therefore, an earlier diagnosis of this dementia is crucial although it is a challenging task. Recently, many studies have proposed biomarkers to perform early detection of Alzheimer's disease. Some of them have proposed methods based on inter-subject similarity while other approaches have investigated framework using intra-subject variability. In this work, we propose a novel framework combining both approaches within an efficient graph of brain structures grading. Subsequently, we demonstrate the competitive performance of the proposed method compared to state-of-the-art methods.
