Abstract
Alzheimer's disease (AD) is the most common neurodegenerative disorder for those 65. years or older, currently affecting 4.5. million Americans and predicted to rise to 13.2. million by the year 2050 in the US alone. Neuroimaging and brain mappping techniques offer extraordinary power to understand AD, providing spatially detailed information on the extent and trajectory of the disease as it spreads in the living brain. Computational anatomy techniques, applied to databases of MRI scans, reveal the dynamic sequence of brain changes with disease progression, and how these changes relate to cognitive decline and the spread of amyloid plaque and tangle pathology, the molecular causes of AD.
