Mettre la maladie d'Alzheimer en images

In 2009, the diagnosis of Alzheimer's disease remains difficult. None of the clinical, biological or imaging approaches is itself sufficient to reach it. Despite the fact that the clinical approach remains essential, new neuro-imaging techniques have recently been developed (structural, metabolic, molecular or functional) to better diagnose this disease but also to try to decipher its pathophysiology. In this review we will highlight the recent developments of these neuro-imaging tools and consider how they can help to make a precise and early diagnosis of Alzheimer's disease.
