Filter by:The purpose of this research study is to investigate how the brain and motor behavior changes both in individuals with spinocerebellar ataxia and healthy individuals, and to assess whether a therapeutic intervention reduces levels of uncoordinated movement and improves motor function in spinocerebellar ataxia (SCA).
The purpose of this study is to evaluate the safety, tolerability and pharmacokinetics of RT001 in patients with Friedreich's ataxia.
This study will explore whether methylprednisolone treatment is safe, well-tolerated, and beneficial in patients that are diagnosed with Friedreich Ataxia (FRDA). The study will also explore if methylprednisolone has any effects on biomarkers associated with FRDA. All subjects in the study will receive the same steroid treatment.
The purpose of this phase 3 randomized, multi-center, double-blind, placebo-controlled study is to evaluate the efficacy and safety of ACTIMMUNE® (interferon-γ 1b) in the treatment of Friedreich's Ataxia (FA) and to evaluate the pharmacokinetic (PK) characteristics of ACTIMMUNE® in FA patients.
All the studies underlined the high frequency of co-morbid associations in specific learning disorders. Understanding the reasons for these associations could enable us to determine the cerebral bases that underlie each disorder. Their frequent association suggests the etiological bases are partly common, it seems logical to turn to explanatory models of various common specific disorders. The model recently proposed by Nicholson & Fawcett (2007) suggests a specific disorder of procedural learning. But the brain networks involved in this learning could be achieved separately. We intend therefore to study the neural networks involved in learning procedural and compare networks recruited among children with specific learning disorder alone or in combination (co-morbidity). The children included in the study have either a Developmental Dyslexia or a Developmental Coordination Disorder, or both. The procedure includes a neuropsychological evaluation and a brain MRI study with a morphological and a functional part. During fMRI the child realizes a automated motor task contrasting with a task involving learning procedural.
Ataxia telangiectasia (A-T) is a rare devastating human recessive disorder characterized by progressive cerebellar ataxia, immunodeficiency, chromosomal instability, and cancer susceptibility. In addition to that, a high percentage of patients show dystrophy, growth retardation and poor weight gain. Nevertheless, there are only a few studies assessing this problem. Aim of the present proposal is to investigate the exact body composition, manual muscle strength and hormonal status in patients with A-T compared to healthy controls matched for gender and age. A pelvic sonography in females was performed in order to evaluate the sexual maturity of their inner genitalia. Tanner score was determined to define the physical development. Every subject received a nutritional diary to review its calorie intake and the quality of diet. The investigators expect that the A-T cohort shows an altered body composition, impaired muscle strength, changed hormonal status concerning the sexual hormones and a delayed physical development compared to healthy controls.
Death in Ataxia telangiectasia (A-T) is usually due to cancer or chronic lung failure around 20 years of age. Despite low lymphocyte counts (CD3, CD4, CD8 and CD19), IgA and IgG subclass deficiency opportunistic and acute severe respiratory infections are rare. The prevailing wisdom is that an immunoglobulin replacement therapy is not necessary in most of the patients. However no placebo controlled trials have been performed so far. The aim of this trial was to investigate the prevalence of mild and severe respiratory infections and / or chronic cough in classical A-T patients compared to healthy controls.
We propose a study on Ataxia with oculomotor apraxia type 1 (AOA1) in which Coenzyme Q10 (CoQ10) deficit has been observed. Main objectives of the study are : - To monitor evolution of albumin in patients affected with AOA1 while supplemented with CoQ10 ; - To measure with clinical scales and biological markers efficacy of supplementation on disease evolution. AOA1 is characterised by Hypoalbuminemia. Disease duration is negatively correlated with albumin level. This study aims to understand mechanisms of the disease and our hypothesis is that correction or stabilization of albumin level with CoQ10 supplementation could impact disease evolution. The study is planned from 1 to 2 years supplementation. The CoQ10 is classified as a food supplement and has already been tested in other neurological conditions.
Ataxia telangiectasia (A-T) is a rare devastating human recessive disorder characterized by progressive cerebellar ataxia, immunodeficiency, chromosomal instability, and cancer susceptibility. The underlying mechanism and process of neurodegeneration leading to loss of cerebellar neurons and neurological function is largely unknown. Laboratory diagnostic approaches to neurodegeneration in A-T are hampered by sampling issues. It is dangerous, impractical, and not ethically to directly sample brain tissue by surgical biopsy. In contrast cerebrospinal fluid (CSF), a fluid that is in direct contact with brain tissue, is relatively easy to sample in a safe procedure (lumbar puncture). The aim of the proposal is to investigate oxidative stress, low grade inflammation and tissue break down in the brain of A-T patients by analyzing CSF. In addition the alterations in protein expression related to A-T will be quantified by liquid chromatography/mass spectrometry (LC/MS)-based proteomic analysis of CSF from healthy individuals and A-T patients to determine candidate proteins (new biomarkers) which relative expression levels could be used as surrogate marker of disease progression.
The objective of this study is to determine if citocoline is effective for balance abnormalities and to stabilize cognitive decline in patients with fragile X-associated tremor ataxia syndrome. The study will test 1000mg twice daily of citocoline for 12 months in an open label pilot study, with study visits at baseline, 3, 6, and 12 months.
