Posterior cortical atrophy with unilateral occipito-temporal degeneration

Posterior cortical atrophy (PCA) was first described by Benson in1988 as a variant of Alzheimer’s disease (AD) with atypical clinical presentation [2]. At onset, patients usually complain of visual symptoms such as visual agnosia and show features of Balint’s and Gerstmann’s syndromes or apraxic disorders [1, 3]. Memory and language are impaired later in the course of the disease. Neuroimaging studies have revealed bilateral posterior cortical atrophy and hypoperfusion [3, 5]. We report a case of a woman with clinical features of posterior cortical atrophy due to unilateral occipito-temporal degeneration.
