After the intervention, patients will be reassessed with a clinical and neurophysiological evaluation at 2 weeks, 1 months and 3 month after treatment. [clinicaltrials.gov]

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]

But some possible breakthrough treatments are being studied. Some medicines with antioxidant properties have shown some promise. Treatment focuses on easing symptoms and maintaining comfort and function for as long as possible. [cedars-sinai.org]

What is the prognosis for ataxia? Ataxia is the sign of an underlying disease or illness and the prognosis depends upon the response to treatment of that underlying cause. [medicinenet.com]

Prognosis The prognosis depends on the age of symptom onset. An earlier onset is associated with a more severe and rapidly progressive disease. The documents contained in this web site are presented for information purposes only. [orpha.net]

Prognosis for Friedreich’s Ataxia The symptoms of Friedreich's ataxia can shorten life expectancy, especially when heart disease is a factor. However, some people with less severe cases of Friedreich's ataxia live full lifespans. [quantumrehab.com]

Disease progression and severity often depend on the type of SCA. [1] Most available information on the prognosis of SCA is based on the four most common types: SCA1, SCA2, SCA3 and SCA6. [rarediseases.info.nih.gov]

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

Etiology SCA7 is due to a CAG trinucleotide repeat in the ataxin 7 ( ATXN7 ) gene (3p21.1-p12). This mutation leads to degeneration in the cells of the retina, cerebellum and brainstem. [orpha.net]

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

While the etiology of each SCA is unique and some are still unknown, many are caused by an expansion of Cytosine-Adenine-Guanine (CAG) nucleotide repeats. [eyewiki.aao.org]
