Posterior cortical atrophy (PCA) is a progressive neurodegenerative condition that affects parietal, occipital, and occipitotemporal regions of the brain. We report a case of PCA in a patient who presented with two and a half-year history of progressive cognitive decline affecting mainly visual perception and praxis skills. She saw an optometrist and was prescribed glasses that did not help She reported that over the six months prior to presentation, her family told her she made mistakes with household tasks and had some difficulties operating the computer and writing at work. Over the previous six months, the family noted that she made mistakes with household chores and they were informed of her difficulties at work, mainly operating computer and writing Her condition gradually progressed since the family first noticed it to the extent that she was misplacing things around the house, could forget details of the conversation and her mobility was affected.
