Alzheimer’s disease is an important social and economic issue for our societies. The development of therapeutics against this severe dementia requires assessing the effects of new drugs in animal models thanks to dedicated biomarkers. This review first overviews Alzheimer’s disease and its models as well as the concept of biomarkers. It then focuses on MRI and NMR biomarkers of Alzheimer’s disease in animals. Anatomical markers such as atrophy and angiography are useful to phenotype newly developed models of Alzheimer’s disease, even if the alterations in these animals are not as severe as in humans. Amyloid plaques imaging is a promising marker of the pathology in animals, and is a rapidly evolving field of MRI. Functional methods such as perfusion and diffusion imaging or spectroscopy are able to detect alterations in transgenic mice mimicking Alzheimer and also to show similar alterations than in humans. They can thus be good translational markers of the disease. Manganese-Enhanced MRI shows a reduction of neuronal transportation in transgenic models of Alzheimer and it allows monitoring improvements induced by treatments of the disease. It is thus a promising biomarker of the pathology in animals.

I thank Libertas for the guidance, speed and encouragement they provided from my first submission until publication. I appreciate the patience and support of everyone I communicated with. Your services are user-friendly. I intend to submit more articles to your journals.
All authors are surveyed after their articles are published. Authors are asked to rate their experience in a variety of areas, and their responses help us to monitor our performance. Presented here are their responses in some key areas. No 'poor' or 'very poor' responses were received; these are represented in the 'other' category.See Our Results
