Posterior cortical atrophy is a rare, degenerative brain and nervous system disorder (neurological condition) that causes your vision to decline. The vision problems result from a disease of your brain. Common symptoms include difficulties with reading, recognizing common objects and recognizing familiar faces. It may eventually cause your memory and thinking abilities (cognitive skills) to decline. Posterior cortical atrophy may be associated with Alzheimer's disease, Lewy body dementia or other neurological conditions.
