Filter by:The aim of the study is to evaluate the effects on motor and cognitive performance of transcranial alternating current stimulation (tACS) compared to transcranial direct current stimulation (tDCS) and placebo stimulation (sham) in patients with neurodegenerative ataxia to identify a possible rehabilitation protocol.
This is a longitudinal, triple-blind, randomized-controlled, prospective observational study assessing patients with cerebellar ataxia, including spinocerebellar ataxia type 3 (SCA3) and multiple system atrophy-cerebellar type (MSA-C), to examine the efficacy, safety, and tolerability of transcranial alternating current stimulation (tACS) for up to 3 months.
Machado-Joseph Disease (MJD) or spinocerebellar ataxia type 3 (SCA3) is the most common spinocerebellar ataxia worldwide.Repetitive transcranial magnetic stimulation (rTMS) is a form of brain stimulation therapy used to treat depression and cerebellar ataxias. In this randomized, double-blind, sham-controlled study, the investigators will evaluate whether a 15 day treatment with 1 Hz of repetitive transcranial magnetic stimulation (rTMS) can improve symptoms (motor symptoms and non-motor symptoms) in patients with MJD.
Phase 2b/3 double blind, randomized, placebo-controlled trial to assess safety and efficacy of SLS-005 (trehalose injection, 90.5 mg/mL for intravenous infusion) for the treatment of adults with spinocerebellar ataxia).
The aim of the research is to improve motor function in people with cerebellar ataxia by using neuroimaging methods and mental imagery to "exercise" motor networks in the brain. The relevance of this research to public health is that results have the potential to reduce motor deficits associated with cerebellar atrophy, thereby enhancing the quality of life and promoting independence.
This study aim to investigate the neuroimaging changes of hereditary ataxia patients, especially in the SCA3 patients in preclinical or mild stage.
The investigators aimed to find appropriate biomarkers such as serum neurofilament light chain in reflecting disease severity in hereditary ataxia from a large cohort during long-term follow-up. The disease severity is indicated by clinical scales and brain MRI tests.
The primary objective of this study is to evaluate the safety and tolerability of multiple ascending doses of BIIB132 administered via intrathecal (IT) injection to participants with spinocerebellar ataxia type 3 (SCA3). The secondary objective of this study is to characterize the multiple-dose pharmacokinetics (PK) of BIIB132 administered via IT injection to participants with SCA3.
Spinocerebellar ataxia type 3 (SCA3) is one of autosomal dominant hereditary ataxias. Standing imbalance, unsteady gait, dysmetria, fatigue, and depression would occur gradually. There are no effective treatment or palliative methods for patients in the present days. However, low-dose growth hormone, or its downstream product, insulin-like growth factor I (IGF-1), may deter the progress of SCA3 in transgenic mice. The main bioactive constituent among the Chinese medicine WT possesses neuroprotective function against glutamate-induced toxicity, which is one major pathology of SCA3. It promotes neurogenesis, and increases the protein expression of IGF-1 in ischemic brains of rats. Thus, we designed a randomized, double-blind trial for patients with SCA3, if WT is a possible neuroprotective medicine. All the subjects will be recruited from Changhua Christian Hospital. Diagnosis is confirmed by gene test and magnetic resonance image by a neurologist. They will be assigned in random and double blind, prescribed with 3 grams concentrated powder of WT or placebo, twice a day, for 12 weeks. After the washout period of 4 weeks, there will be a crossover of placebo or WT for another 12 weeks. After that, another 4-week rest will be followed by the end of trial. Check items in five check points include: 1. Blood examination (serum IGF-1, Neurofilament light chain, mitochondria copy number, 8_OHdG, delta-Ct), 2.Neurological exam (Scale for the Assessment and Rating of Ataxia), 3. Questionnaires (Modified Fatigue Impact Scale, Epworth Sleepiness Scale), 4. Handgrip strength test (which is correlated to IGF-1 value in elderly), and 5. serum metabolites, . All the data will be disclosed after the end of trial. Paired-T test or Wilcoxon Ranked Sign Test will be operated in SPSS.
Inherited movement disorders are rare conditions, whose cumulative prevalence are in the order of 5-10/100,000 inhabitants, in most cases progressive and can lead to a significant loss of autonomy after one or more decades of evolution. They include spinocerebellar ataxias and hyperkinetic disorders (dystonias, choreas, tremor, parkinsonism and myoclonus with variable combination of those, or more complex alteration of movements). The existence of the National Reference Centre (CMR) for Rare Diseases (CMR Neurogenetics, devoted to ataxias and spastic paraparesis, dystonia and rare movement disorders and CMR Huntington, devoted to Huntington Disease) has allowed a more integrated vision of these diseases. This is illustrated, in the same family, by the occurrence of different clinical expressions of spinocerebellar ataxias and hyperkinetic disorders that share the same genetic background. Conversely, different causal mutations within the same gene may have very different ages at onset and a wide range of clinical expression, and the spectrum of new phenotypes linked to a single gene is still expanding . Many ataxia and dystonia genes are involved in similar pathways. There are numerous arguments supporting a share pathogenesis including synaptic transmission and neurodevelopment . BIOMOV project aims to : 1. establish the clinical spectrum and natural history of these diseases, 2. understand the role of genetic and familial factors on the phenotype, 3. elucidate the molecular basis of these disorders and evaluate diagnostic strategies involving molecular tools for clinical and genetic management, 4. develop multimodal biomarkers both for physiopathological studies and for accurate measures of disease progression, 5. develop trial ready cohorts of well characterized genetic patients, 6. test new therapies either symptomatic or based on pathophysiological mechanisms.
