In this article, we present an innovative MRI-based method for Alzheimer disease
(AD) detection and mild cognitive impairment (MCI) prognostic, using lifespan
trajectories of brain structures. After a full screening of the most discriminant
structures between AD and normal aging based on MRI volumetric analysis of 3,032
subjects, we propose a novel Hippocampal-Amygdalo-Ventricular Atrophy score
(HAVAs) based on normative lifespan models and AD lifespan models. During a
validation on three external datasets on 1,039 subjects, our approach showed very
accurate detection (AUC ≥ 94%) of patients with AD compared to control subjects
and accurate discrimination (AUC = 78%) between progressive MCI and stable MCI
(during a 3-year follow-up). Compared to normative modeling, classical machine
learning methods and recent state-of-the-art deep learning methods, our method
demonstrated better classification performance. Moreover, HAVAs simplicity makes
it fully understandable and thus well-suited for clinical practice or future
pharmaceutical trials.
