“Didy,” a clinical case of cognitive dysfunction syndrome

The term cognitive dysfunction syndrome (CDS) has been used to refer to the changes of behavior related to aging with cognitive skills deterioration, that do not stem completely from medical conditions and that are a consequence of a degenerative process of the central nervous system. It is known that the CDS in dogs is caused by the physical and chemical changes that take place in the brain due to aging. The aim of this paper is to present a clinical case of CDS which was clinically diagnosed and then confirmed by necropsy at the veterinary hospital of the National Autonomous University of Mexico.
