SCA3 type 1 (MJD Type 1, see this term) is associated with ataxia, ophthalmoparesis, pyramidal signs such as spasticity and hyperreflexia, and extrapyramidal signs including dystonia and other movement disorders presenting in adolescence.[orpha.net]
Discussion Spinocerebellar ataxia type 7 (SCA 7) is a polyglutamine (polyQ) neurodegenerative disease characterized by progressive cerebellar ataxia and retinal degeneration with ophthalmoplegia, hyperreflexia, sensory loss, dysarthria, and dysphagia.[oatext.com]

Overall, our case series extends the phenotype and suggests that protein kinase Cγ gene mutations should be considered in patients with slowly progressive autosomal dominant cerebellar ataxia, particularly when myoclonus, dystonia, or mildcognitiveimpairment[discovery.ucl.ac.uk]
Summary An autosomal dominant ataxia with isolated cerebellar signs, slow progression, mildcognitiveimpairment, and absence of cerebellar oculomotor signs may suggest the p.Arg420His allelic form of SCA13.[link.springer.com]

One individual (diabetic) had absentdeeptendonreflexes. None had extensor plantar reflex, chorea, dystonia, tremor, or other extrapyramidal signs. Three individuals reported mild bladder control issues, and one had nocturnal enuresis.[link.springer.com]
In selected patients with lower cranial dystonia, especially jaw and tongue dystonia, SCA2 might be considered during the diagnostic workup.[movementdisorders.org]
In addition, new neurophysiological and imaging techniques are discussed, along with an in-depth examination of the treatment and management protocols of ataxic diseases.[books.google.de]

This results in neurons with longer after-hyperpolarizations and thus, a decreased maximal firing rate. [3] Prognosis There is no known prevention of spinocerebellar ataxia.[ipfs.io]
Diagnosis and Prognosis: Neurologists and ophthalmologists working together usually can make this diagnosis, especially if there is a family history.[disorders.eyes.arizona.edu]
PrognosisPrognosis is poor but patients have been reported to survive for decades after onset of symptoms.[orpha.net]
Beginning with an examination of the cerebellar region, and then progressing to a fresh perspective on the clinical aspects of the various forms of ataxia, this handbook gives clinicians a state-of-the-art reference for the management of the many etiologies[books.google.de]
Identification of KCNC3 mutations contributes a new class of genes to causative etiologies of progressive degenerative ataxias.[ashg.org]
Thus, it seems unlikely that expansion alone causes SCA8; other genetic mechanisms may be necessary to explain SCA8 etiology.[discovery.ucl.ac.uk]

Pathophysiology [ edit ] Most cases of SCA6 are a result of CAG repeat expansion beyond the normal range, i.e., more than 19 repeats, in the Ca v 2.1 calcium channel encoding gene CACNA1A. [1] This gene has two splice forms , "Q-type" and "P-type", and[en.wikipedia.org]
