Primary progressive visual-spatial impairment – http://id.who.int/icd/entity/629275507

A type of posterior cortical atrophy that is associated with degeneration of the parietal and/or occipital lobes leading to isolated deficits in primary and higher order visual perception, including alexia (inability to read), simultagnosia (inability to recognise two objects simultaneously), and neglect (inattention to part of the visual field). It is most commonly associated with Alzheimer disease, but also Lewy body disease, corticobasal degeneration, and others.
