background: ataxia with oculomotor apraxia type 1 (aoa1) shows early onset with autosomal recessive inheritance and is caused by a mutation in the aprataxin (aptx) gene encoding for the aptx protein. methods: in this study, a 7-year-old girl born of a first-cousin consanguineous marriage was described with early-onset progressive ataxia and aoa, with increased cholesterol concentration and decr...

Nonparaneoplastic opsoclonus-myoclonus ataxia syndrome is a rare neuroinflammatory condition featured by opsoclonus, myoclonus, ataxia, and cognitive behavioral disturbance. The authors report an observation of enterovirus 71-associated opsoclonus-myoclonus ataxia syndrome evolving toward full recovery on intravenous intravenous immunoglobulin (IG) treatment. Based on this case report, enterovi...

BACKGROUND Deep brain stimulation (DBS) has been utilized to treat various symptoms in patients suffering from movement disorders such as Parkinson's disease, dystonia, and essential tremor. Though ataxia syndromes have not been formally or frequently addressed with DBS, there are patients with ataxia and associated medication refractory tremor or dystonia who may potentially benefit from thera...

Spinocerebellar ataxias 6 and 7 (SCA6 and SCA7) are neurodegenerative disorders caused by expansion of CAG repeats encoding polyglutamine (polyQ) tracts in CACNA1A, the alpha1A subunit of the P/Q-type calcium channel, and ataxin-7 (ATXN7), a component of a chromatin-remodeling complex, respectively. We hypothesized that finding new protein partners for ATXN7 and CACNA1A would provide insight in...

the hereditary ataxias comprise a wide spectrum of heterogeneous disorders that share three features: ataxia, involvement of cerebellum or its connections, and heritability. in many hereditary ataxias, the underlying gene mutations have been identified. knowledge of the causative mutations allows a rational classification of hereditary ataxias as autosomal recessive, autosomal dominant or mater...

Ataxia is a common and important neurological finding in medical practice. Severe deficiency of Vitamin E can profoundly affect the central nervous system and can cause ataxia and peripheral neuropathy resembling Friedreich's ataxia. Vitamin E deficiency can occur with abetalipoproteinemia, cholestatic liver disease or fat malabsorption. Ataxia with isolated Vit E deficiency (AVED) is an Autoso...

Mutations of voltage gated calcium channels are commonly associated with episodic ataxia. There has been no case reports in the literature that describe anon-episodic presentation of ataxia in patients affected with this mutation. This current case report describes a 61-year-old female patient with progressive ataxia and mutations that commonly cause an episodic ataxia. ABBREVIATIONS EA2: Episo...

Background: Progressive ataxias are complex disorders that result in a wide variety of symptoms. Whilst we currently have relatively good understanding the symptom patterns associated with various types ataxia, and how these diseases progress over time, their impact on person ataxia is less well understood. In addition, little known about carers, friends families aff...

Friedreich's ataxia (FRDA) is an inherited, neurodegenerative disease that typically presents in childhood and results progressive gait limb ataxia, with the extraneural features of hypertrophic cardiomyopathy, diabetes scoliosis. The genetic defect a deficiency frataxin protein, which important for mitochondrial function, especially brain heart. Drug development has approached FRDA through pat...
