You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments. [rarediseases.info.nih.gov]

After treatment, frequency of SI was reduced to about 40/min and 75/min and amplitude significantly decreased to 2,9 and 3,5 , respectively. [neurology.org]

To identify relevant publications, a PubMed search using the terms “treatments of cerebellar ataxias,” “degenerative cerebellar ataxia treatment,” and “treatment of hereditary cerebellar ataxia” was conducted. [movementdisorders.org]

Management and treatment For most ARCA there is no specific drug treatment, except for coenzyme Q10 deficiency and abetalipoproteinemia. The documents contained in this web site are presented for information purposes only. [orpha.net]

Prognosis Prognosis is highly variable between the different types but improvement is unlikely. [patient.info]

(See 'Prognosis' above and 'Treatment' above.) SCA3, also known as Machado-Joseph disease, is the most common type of SCA (table 1). SCA types 9 through 36 are rare and less well characterized. (See 'Classification of SCA' above.) [es.slideshare.net]

Co Q10 supplementation (300 to 600 mg/day) for coenzyme Q10 deficiency. [6] Prognosis [ edit ] In most cases, between the age of 2 and 4 oculomotor signals are present. Between the age of 2 and 8, telangiectasias appears. [en.wikipedia.org]

Treatment and prognosis Edit There is no known cure for spinocerebellar ataxia, which is a progressive disease (it gets worse with time), although not all types cause equally severe disability. [psychology.wikia.com]

CCA was defined as an SCA of unknown etiology with imaging evidence of isolated cerebellar atrophy. [movementdisorders.org]

Etiology These diseases are caused by mutations in specific genes, some of which have been identified, such as frataxin in Friedreich ataxia, alpha-tocopherol transfer protein in ataxia with vitamin E deficiency (AVED), aprataxin in ataxia with oculomotor [orpha.net]

All possible etiologies should be considered when the clinical course is not firmly established. [practicalneurology.com]

[…] the prevalence of ataxia of all causes. [1] [2] Epidemiologic studies that focus on hereditary types of ataxia have shown a prevalence of around 10 per 100,000 population, and idiopathic ataxia probably outnumbers hereditary cases. [3] Since there are [online.epocrates.com]

Consequently, they are often approached together in epidemiological studies. [karger.com]

Summary Epidemiology This group encompasses a large number of rare diseases, the most frequent in the Caucasian population being Friedreich ataxia (estimated prevalence 2-4/100,000), ataxia-telangiectasia (1-2.5/100,000) and early onset cerebellar ataxia [orpha.net]

They further suggest that epidemiological studies should be conducted to refine the genotype/phenotype correlation in the different ARCA conditions and establish a more accurate and detailed clinical characterization of each one. [friedreichsataxianews.com]

Prevention Genetic testing enables identification of the causative gene in 50-80% of cases of ADCA [ 15 ]. Pre-symptomatic testing is available but not always wanted. It is usually requested for family planning purposes. [patient.info]
