Topic: Amyloid, tau and blood-test diagnosis

Background and purpose The necessity for structural MRI is greater than ever to both diagnose AD in its early stage and objectively evaluate its progression. We propose a new VBM-based software program for automatic detection of early specific atrophy in AD. Materials and methods A target VOI was determined by group comparison of 30 patients with very mild AD and 40 age-matched healthy controls by using SPM. Then this target VOI was incorporated into a newly developed automated software program independently running on a Windows PC for VBM by using SPM8 plus DARTEL. ROC analysis was performed for discrimination of 116 other patients with AD with very mild stage (n = 45), mild stage (n = 30) and moderate-to-advanced stages (n = 41) from 40 other age-matched healthy controls by using a z score map in the target VOI. Results Medial temporal structures involving the entire region of the entorhinal cortex, hippocampus, and amygdala showed significant atrophy in the patients with very mild AD and were determined as a target VOI. When we used the severity score of atrophy in this target VOI, 91.6%, 95.8%, and 98.2% accuracies were obtained in the very mild AD, mild AD, and moderate-to-severe AD groups, respectively. In the very mild AD group, a high specificity of 97.5% with a sensitivity of 86.4% was obtained, and age at onset of AD did not influence this accuracy. Conclusions This software program with application of SPM8 plus DARTEL to VBM provides a high performance for AD diagnosis by using MRI.

Key findings

Why it matters

A new automated MRI analysis method detected atrophy in medial temporal structures and distinguished very mild, mild, and moderate-to-severe Alzheimer disease from healthy controls with accuracies of 91.6%, 95.8%, and 98.2%. This is a diagnostic tool only and does not treat, cure, or prevent the disease.
