Posterior Cortical Atrophy

Posterior cortical atrophy is a progressive neurodegenerative disorder that predominantly affects the occipital cortex and is referred to as a “visual variant of Alzheimer’s disease.” PET/MR imaging demonstrates hypometabolism in the parieto-occipital areas with relative sparing of the cingulate gyrus as well as in the bilateral frontal eye field regions. Cortical volume loss is seen later in the disease course.
