In the history of experimental demyelination, allergic encephalomyelitis (EAE) is the most impressive experimental demyelinating disease based on an immunological mechanism. The evolution of the neuropathological process of chronic EAE is very close to that of chronic Multiple Sclerosis. On the other hand experimental inoculation of different viruses can induce various types of demyelination depending on the main target of the virus and the host response, this latter being conditioned by the age, the mechanism of immunity and the persistence of the virus in the brain. The demyelination can be induced by a viral persistent infection primarily affecting oligodendrocytes (CDV, JHM hepatitis virus) or acting through an immunomediate response against myelin (Visna, Theiler virus, human conventional viruses). The experimental demyelinating models show that also in Multiple Sclerosis a viral etiology could be the starting point of a demyelinating process based on a immunologically mediated mechanism.

In an attempt to associate the clinical neurological syndromes with the neuropathological features of canine distemper (CD), 19 spontaneous cases with neurological involvement were examined, before and after euthanasia. Seventeen dogs were less than one year of age and all except two (89.4%) were unvaccinated against CD. Various extraneural signs associated with CD encephalomyelitis (CDE) were seen in 15 dogs. Generalized or localized myoclonus was the most common sign observed (13/19). Seventeen of the dogs presented with signs suggestive of one neuroanatomical location of lesions. Of these animals, seven had signs of cerebral, two of cerebellar, four of cervical, one of cervicothoracic, two of thoracolumbar and two of lumbosacral syndrome. The diagnosis of CD was confirmed immunohistochemically (detection of CD viral antigen), serologically (neutralizing serum antibody titre > or = 16) and histopathologically (CDV inclusion bodies, type of central nervous system lesions). An association of the neuroanatomical lesion location and the histopathological findings was noted in 14 out of 17 dogs (82.3%). Myoclonus could be attributed to lower motor neuron damage in eight out of 13 dogs (61.5%).
