Posterior cortical atrophy
- Posterior cortical atrophy
Posterior cortical atrophy (PCA), also called Benson's syndrome, is the visual variant of Alzheimer’s disease [Nestor PJ, Caine D, Fryer TD, Clarke J, Hodges JR: [http://jnnp.bmj.com/cgi/content/abstract/74/11/1521?ijkey=c324f6cfb6032c6e43e57b25d351e40cd607348e&keytype2=tf_ipsecsha The topography of metabolic deficits in posterior cortical atrophy (the visual variant of Alzheimer’s disease) with FDG-PET] . J Neurol Neurosurg Psychiatry 2003; 74:1521–1529] . The disease causes shrinkage (atrophy) of the back (posterior) part of the brain (cortex). It is a clinical syndrome in which complex visual processing is progressively disrupted owing to a neurodegenerative disorder. PCA was first described by Franck Benson in 1988.
Renowned fantasy fiction writer Terry Pratchett has been diagnosed with this disease. [cite web
