Scoliosis in Friedreich’s Ataxia [PDF]

Canadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 1982
SUMMARY:The preliminary results based on a three year study on the evolution and management of scoliosis in Friedreich’s ataxia are presented. Thirty-two patients were followed in the Neuromuscular Disease Clinic at Sainte-Justine Hospital where standardized spinal radiographs were taken periodically with the Scoliosis Chariot and the Throne ...

Sensitivity of Neuroimaging Indicators in Monitoring the Effects of Interferon Gamma Treatment in Friedreich’s Ataxia

Frontiers in Neuroscience, 2020
The identification of efficient markers of disease progression and response to possibly effective treatments is a key priority for slowly progressive, rare and neurodegenerative diseases, such as Friedreich’s ataxia.

Cardiomyopathy of Friedreich Ataxia [PDF]

Journal of Neurochemistry, 2013
AbstractFriedreich's ataxia is a rare hereditary, predominantly neurologically defined multisystem disorder of mitochondrial function. Although the gene defect has been identified, the precise pathophysiology of the deficient mitochondrial protein, frataxin, is unknown. Besides the characteristic features of spinocerebellar ataxia the heart may also be

Friedreich Ataxia [PDF]

Journal of the Neurological Sciences, 2003
There has been rapid progress in the understanding of several aspects of Friedreich's ataxia (FA) since the gene mutation was identified in 1996. At the clinical level, now it is possible to confirm that the majority of patients fullfilling clinical criteria for classic FA have the FA gene mutation but some do not, indicating genetic heterogeneity ...

Sensory ataxia and cardiac hypertrophy caused by neurovascular oxidative stress in chemogenetic transgenic mouse lines

Nature Communications, 2023
Oxidative stress is associated with cardiovascular and neurodegenerative diseases. Here we report studies of neurovascular oxidative stress in chemogenetic transgenic mouse lines expressing yeast D-amino acid oxidase (DAAO) in neurons and vascular ...

In vivo overexpression of frataxin causes toxicity mediated by iron-sulfur cluster deficiency

Molecular Therapy: Methods & Clinical Development, 2022
Friedreich's ataxia is a rare disorder resulting from deficiency of frataxin, a mitochondrial protein implicated in the synthesis of iron-sulfur clusters.

Dysphagia in Friedreich Ataxia [PDF]

Dysphagia, 2017
The objective of the study was to comprehensively characterise dysphagia in Friedreich ataxia (FRDA) and identify predictors of penetration/aspiration during swallowing. We also investigated the psychosocial impact of dysphagia on individuals with FRDA.

Symptom burden of people with progressive ataxia, and its wider impact on their friends and relatives: a cross-sectional study [version 2; peer review: 1 approved, 2 approved with reservations]

AMRC Open Research, 2023
Background: Progressive ataxias are complex disorders that result in a wide variety of symptoms. Whilst we currently have a relatively good understanding of the spectrum of symptoms associated with the various types of ataxia, and their progression over ...

The smoothened agonist SAG reduces mitochondrial dysfunction and neurotoxicity of frataxin-deficient astrocytes

Journal of Neuroinflammation, 2022
Background Friedreich’s ataxia is a rare hereditary neurodegenerative disease caused by decreased levels of the mitochondrial protein frataxin. Similar to other neurodegenerative pathologies, previous studies suggested that astrocytes might contribute to

Friedreich ataxia: an overview [PDF]

Journal of Medical Genetics, 2000
Friedreich ataxia, an autosomal recessive neurodegenerative disease, is the most common of the inherited ataxias. The recent discovery of the gene that is mutated in this condition,FRDA, has led to rapid advances in the understanding of the pathogenesis of Friedreich ataxia. About 98% of mutant alleles have an expansion of a GAA trinucleotide repeat in
