[Brain functional imaging in Alzheimer's disease]. / L'imagerie cérébrale fonctionnelle dans la maladie d'Alzheimer.

ABSTRACT

Alzheimer's disease is nowadays the leading cause of dementia. It affects more than a third of people over 85 years old. The gold standard diagnostic proof is currently based upon pathology examination. It seems rather crucial to find methodologies that make an early and accurate in vivo diagnosis so as to offer the patient the most suitable treatment. We hereby go over several available neuro-imaging techniques used in nuclear medicine that increase the diagnostic accuracy of Alzheimer's disease.
