Canine distemper virus causes a multi systemic disease in dogs often with severe neurological signs. These signs are the result of viral replication in neurons and glial cells leading to grey matter lesions and demyelination. Inflammation leads to further destruction of the tissue. As extraneural signs are often lacking and only one localisation may be found on neurological examination, distemper may be difficult to diagnose. Myoclonus is almost pathognomonic for this disease but occurs in less than half of the cases. The inflammation of the central nervous system that occurs during the chronic stage of the disease can be detected on examination of the cerebrospinal fluid, in particular by determination of the IgG index. Viral antigen can be demonstrated in cerebrospinal fluid cells by fluorescent antibody techniques. The prognosis of nervous distemper is generally poor although dogs can recover from this disease. Treatment is largely supportive and symptomatic. The importance of regular vaccination is stressed.
