This is a case of a 70-year-old man with severe peripheral neuropathy, type 2 diabetes and progressively worsening cerebellar ataxia. He was found to have circulating antigliadin and antireticulin antibodies compatible with celiac disease in the absence of intestinal pathology. The peripheral neuropathy improved with a gluten-free diet, antioxidants and intravenous immunoglobulin, whereas the a...

Friedreich ataxia (FRDA), the most common autosomal recessive ataxia, is caused in 94% of cases by homozygous expansions of an unstable GAA repeat localised in intron 1 of the X25 gene. We have investigated this mutation in five Brazilian patients: four with typical FRDA findings and one patient with atypical manifestations, who was considered to have some other form of cerebellar ataxia with r...

A 20-year-old man presented with vertigo followed by hourly episodes of dysarthria and incoordination lasting 5–20 seconds (video 1). Neurologic examination was normal between episodes. The only brain/spine MRI lesion in the right superior cerebellar peduncle (figure, A). CSF analysis revealed elevated white blood cells (6/?L [normal, 0–5]) oligoclonal bands (?4). Paroxysmal dysarthria–ataxia a...

BACKGROUND Dentatorubral-pallidoluysian atrophy (DRPLA) is a rare neurodegenerative disorder mainly diagnosed in Japan. Its prevalence is low in other countries. Three phenotypes are described: choreoathetoid movements, cerebellar ataxia, and progressive myoclonic epilepsy. OBJECTIVE To evaluate the frequency of DRPLA in European patients with sporadic or autosomal dominant cerebellar ataxia....

OBJECTIVES The previous finding of an immunologic response primarily directed against transglutaminase (TG)6 in patients with gluten ataxia (GA) led us to investigate the role of TG6 antibodies in diagnosing GA. METHODS This was a prospective cohort study. We recruited patients from the ataxia, gluten/neurology, celiac disease (CD), and movement disorder clinics based at Royal Hallamshire Hos...

Early-onset ataxia with ocular motor apraxia and hypoalbuminemia (EAOH) is a neurodegenerative disorder caused by mutation in the aprataxin (APTX)-coding gene APTX, which involved DNA single-strand break repair (SSBR). The neurological abnormalities associated EAOH are similar to those observed patients ataxia-telangiectasia. However, immunological have not been described. In this study, we rep...

The diagnosis and treatment of cerebellar atrophy remain challenging owing to its nonspecific symptoms laboratory indicators. Three patients with spinocerebellar ataxia type 8 caused by ATXN8OS were found among the 16 people in studied family. clinical manifestations included progressive spastic paraplegia lower extremities, mild ataxia, cognitive impairment, atrophy. After administering antisp...

The clinical management of cerebellar ataxia is challenging, mainly because ataxia is a symptom of many neurological diseases. Many types of ataxia disorders are genetic and some are extremely rare. Here, the authors suggest a diagnostic approach to ataxia developed around a case of sporadic, late-onset, slowly progressive ataxia. Clinical information such as age of onset, rate of progression, ...

The 50 patients in this survey were classified by a panel of neurologists into 4 clinical sub-groups: Group Ia ("typical" Friedreich's ataxia, complete picture), Group Ib ("typical" Friedreich's ataxia, incomplete picture), Group IIa ("atypical" Frriedreich's ataxia, possible recessive Roussy-Levy syndrome), Group IIb (heterogeneous ataxias). The clinical symptoms and signs were analyzed for ea...

Ataxia refers to motor incoordination that is usually most prominent during movement or when a child is attempting to maintain a sitting posture. The first part of the review focuses on the anatomic localization of ataxia--both within the nervous system and without--using a combination of historical features and physical findings. The remainder of the review discusses etiological considerations...
