Abstract
Many of the reports summarizing neurological disorders in cats considered only a limited disease group(s). There is only one large-scale survey on neurological disorders in cats based on the histopathological viewpoint. We described the localizations and frequencies of neurological diseases in a large population of cats that were referred to the Kyoto Animal Referral Medical Center between 2009 and 2016. We attempted to determine the localization of lesions at the time of the examination in each case and to classify the disease etiologies of these 276 cats with neurological disorders retrospectively. There were 174 cases with lesions in the brain region, 14 cases with lesions in the cervical cord region, 34 cases with lesions in the thoracolumbar cord region, and 54 cases with lesions in the peripheral neuromuscular region. High morbidity rates were observed in cases of idiopathic epilepsy and intracranial tumor in the brain region, spinal cord infarction in the cervical cord region, spinal cord infarction and spinal cord tumor in the thoracolumbar cord region, and peripheral vestibular dysfunction arising from otitis media/interna in the peripheral neuromuscular region. It was suggested that there is a higher number of brain diseases than spinal cord and peripheral neuromuscular diseases in cats. Idiopathic and neoplastic diseases were common in the brain region, vascular diseases were common in the spinal cord region, and infectious diseases were common in the peripheral neuromuscular region.
