We still have the occasional Clapham Junction days, now understood and dealt with. Posterior cortical atrophy (PCA), also known as Benson's syndrome See See Posterior cortical atrophy (PCA), is a neurodegenerative syndrome characterized by progressive decline in visual processing and other functions that depend upon the occipitoparietal and occipitotemporal regions of the brain [].PCA is most frequently associated with Alzheimer's disease (AD) and is therefore . Frontal cortex, medial temporal cortex, and hippocampus were spared.

Also known as Benson's syndrome, posterior cortical atrophy (PCA) refers to the progressive and gradual degeneration of the cortex which is the outer layer of the brain in the part of the brain that is located in the posterior (back of the head). PCA was first described by D. Frank Benson in 1988.
