Olivopontocerebellar Atrophy
Olivopontocerebellar atrophy (OPCA) refers to a group of ataxias characterized by progressive neurological degeneration affecting the cerebellum, the pons, and the inferior olives. OPCA may be classified based on clinical, genetic, or neuropathological findings; thus, there are many classifications of the disorder. Among the different classifications there is wide variation in severity and age of onset. The symptoms of OPCA differ from person to person. Most patients experience difficulty with balance and coordination of the legs and arms (ataxia) and slurred speech (dysarthria). Other symptoms may include muscle spasms or weakness and stiffness of the muscles; numbness or tingling of the hands or feet; tremor (shaking) of the hand or arm; reduction or slowness of movements; loss of thinking and/or memory skills; difficulty controlling the bladder or bowels; and feeling faint when standing up. Some patients also have fatigue and/or trouble with sleep. Generally symptoms of OPCA begin in mid-adult life and progress slowly over the course of many years. There is no specific treatment for OPCA. Physicians may try different medications to treat the ataxia, tremor and rigidity that are associated with the disorder. Other treatments are directed at specific symptoms. Stiffness, spasms, sleep disorders, depression, and tremor may be improved with medication.

catalog of human genes and disorders Information Fact sheet from the National Institute of Neurological Disorders and Stroke, NIH The National Ataxia Foundation supporting research into hereditary ataxia GeneClinics a medical genetics resource PERSONS WITH spinocerebellar atrophy, of which there are several types, experience a degeneration of the spinal cord and the cerebellum, the small fissured mass at the base of the brain, behind the brain stem. The cerebellum is concerned with coordination of movements, so atrophy or "wasting away" of this critical control center results in a loss of muscle coordination. Atrophy in the spine can bring spasticity. The basic defect in all types of spinocerebellar atrophy is a an expansion of a CAG triplet repeat. In this way, it is similar to fragile-X syndrome, Huntington disease and myotonic dystrophy, all of which exhibit a triplet repeat expansion of a gene. In the case of spinocerebellar atrophy I, the gene is SCA1, found on chromosome 6. The protein product of the gene - called ataxin-1 - varies in size, depending on the size of the CAG triplet repeat. A homolog of human ataxin-1 has been found in mice, where it is found on chromosome 13 instead of chromosome 6. The two proteins are highly similar, except that in the mouse, the poly-glutamine tract (coded for by the CAG repeat ) is missing, suggesting that it is not essential for normal function in mice.

Background: In 1900, Dejerine and Thomas first introduced the term olivopontocerebellar atrophy (OPCA). Since then, the classification of idiopathic acquired ataxias has evolved a great deal. The initial cases of Dejerine and Thomas involved 2 middle-aged patients with chronic progressive cerebellar degeneration and autopsy findings of gross atrophy of the pons, cerebellum, middle cerebellar peduncle, and inferior olives. OPCA has not been proven to be a single entity. The nosology of these disorders has been extremely confusing, as the OPCAs overlap with spinocerebellar atrophies (SCAs) and multiple system atrophies (MSAs). Clinical distinction of these entities is based on the dominant feature, which may be cerebellar ataxia (observed in OPCA, SCA, and MSA), parkinsonism (observed in MSA), or autonomic failure (observed in MSA). The term OPCA has been retained to describe a form of progressive ataxia distinguished by pontine flattening and cerebellar atrophy on brain imaging studies and at autopsy. Thus defined, OPCA also may qualify as an SCA or as an MSA. While MSAs are sporadic by definition, the genetic bases of the SCAs are increasingly well defined. Since OPCA may exist as a sporadic or inherited disease, categorizing sporadic OPCA as MSA and inherited OPCA as SCA may be appropriate. Differences between sporadic and inherited OPCA in microscopic pathology support this division.

What is Sporadic Olivopontocerebellar Atrophy? Olivopontocerebellar atrophy (OPCA) is almost certainly not a single disease, but a group of diseases. In this brochure, we discuss OPCA that has occurred "sporadically", which means that no one else in the family has ever had the same disorder. In the brochure "Hereditary Olivopontocerebellar Atrophy", we describe forms of ataxia that are known to run in families. Many people do not receive a diagnosis of OPCA until they have seen many different physicians. Physicians also use different terms when they diagnose OPCA. Here is a list of some of the terms, or diagnoses, that physicians may use:
  • olivopontocerebellar atrophy or degeneration
  • olivocerebellar atrophy or degeneration
  • Multisystem atrophy
  • ataxia
  • Marie's ataxia
  • Holmes ataxia
  • Menzel's ataxia
  • ataxia with Parkinsonism, autonomic neuropathy

: Hello: : Can you tell me what diagnostic test currently are used to diagnose and confirm OPCA? : Thank you very much!! Dear Dave: Cerebellar degenerations (also called spinocerebellar degenerations) can either be sporadic or heredofamilial. Heredofamilial cerebellar degenerations can be either autosomal dominant (various types termed spinocerebellar ataxia = SCA 1 - 7, DRPLA, Machado-Joseph disease, etc) or autosomal recessive (Friedreich's ataxia, and some other rare types). The syndrome of progressive ataxia (imbalance of gait, incoordination of hands, slurred speech), in association with some other characteristic abnormalities (peripheral neuropathy, optic atrophy, retinitis pigmentosa, dementia, corticospinal dysfunction, oculomotor dysfunction, etc) is seen with heredofamilial forms. Ataxia is associated with autonomic dysfunction and/or parkinsonian features in sporadic cases. Either sporadic or autosomal dominant forms of cerebellar degeneration can be associated with atrophy of the cerebellum, pons and inferior olives, either on MRI, or at autopsy. Hence, OPCA (olivopontocerebellar atrophy) is used as a descriptive term for these disorders.
