This polytopic pathological background accounts for clinical complexity essentially defined as cerebellar-plus syndrome. Olivopontocerebellar Atrophy OPCA is a group of neurodegenerative disorders that causes the cerebellum pons inferior olivae and other parts of the brain to deteriorate. Drager syndrome striatonigral degeneration and sporadic olivopontocerebellar atrophy are one disease characterised by neuronal multisystem degeneration with unique oligodendroglial inclusion pathology.

OPCA is present in several neurodegenerative syndromes including inherited and non-inherited forms of ataxia such as the hereditary spinocerebellar ataxia known as MachadoJoseph disease and multiple system atrophy. Olivopontocerebellar atrophy OPCA is a pathological label implying not only olivopontocerebellar changes but also cases with more widespread lesions involving the CNS. The sporadic form tends to present in the fifth or sixth decade and is considered a clinical subtype of MULTIPLE SYSTEM ATROPHY.

Multiple-system atrophy In 1984 Duvoisin1 stated that as a nosologic label favor for some time until more satisfactory terminology the cumbersome name olivopontocerebellar atrophy can be evolved to identify the group of the OPCAs as a OPCA would seem neither useful nor convenient. It is important to note that the current belief that olivopontocerebellar degeneration Shy-Drager syndrome and striatonigral degeneration. The use of the term has changed considerably in recent years thanks to the progressing knowledge of.

Olivopontocerebellar atrophy OPCA is a term used to define neuronal degeneration which specifically involves the cerebellum pons and inferior olivary nucleus. Olivopontocerebellar atrophy OPCA defines chronic progressive hereditary usually dominant occasionally recessive rarely sporadic cerebellar degeneration manifested by cerebellar-parkinsonian or parkinsonian-cerebellar syndrome and associated with atrophy of the pontine nuclei and cerebellar cortex and degenerative lesions of the olivopontocerebellar regions.
