posterior cortical atrophy with interesting presentation: case reports

Posterior cortical atrophy (pca) is a rare neuropsychiatric syndrome characterized by the dominancy of visuospatial impairments due to bilateral parieto-occipital divesting with the most common pathological changes presented in typical alzheimer’s disease (ad). we reported 3 cases with similar diagnoses and interesting manifestations in this study. gradual onset and progression of visual deficits without underlying ophthalmologic disease accompanied by intact memory and fluent speech and also the presence of simultagnosia, optic ataxia, oculomotor apraxia, dyscalculia, finger agnosia, and environmental disorientation, and the absence of any history of related diseases; all of them strongly suggesting posterior cortical atrophy.
