Retrospective Analysis of Central Nervous System Diseases in Dogs, with Special Focus on Non-Suppurative Encephalomyelitis (1962-2022).

ABSTRACT: Studies spanning decades provide important information about the epidemiology and occurrence of a broad range of diseases that affect the central nervous system (CNS) of dogs. This study analyzed records and formalin-fixed paraffin-embedded (FFPE) CNS tissue samples from necropsied dogs with neuropathologic changes between 1962 and 2022. A total of 134,854 animals, including 20,117 dogs, were submitted for necropsy during this time span. Of these dogs, 2646 displayed alterations of the CNS. Degenerative and non-suppurative inflammatory lesions were the most common changes, accounting for 35.6% and 28.6%, respectively. Vascular diseases, neoplasms, congenital malformations, and suppurative inflammation represented 13.8%, 8.6%, 7.2%, and 5.4% of cases, respectively. Morbillivirus canis, the
