Filter by:The principal study goals are to determine if a randomized control trial would be feasible, particularly with regards to i) recruitment and retention of parents of children having a diagnosis or a suspicion of diagnosis of DCD, and ii) parents' utilization of the teleintervention. The study will also examine quantitatively and qualitatively families' acceptability of- and satisfaction with the teleintervention.
OBJECTIVE: To measure the tricarboxylic acid (TCA) cycle rate in the dentate nucleus in a group of control subjects and subjects with Friedreich's Ataxia (FRDA). HYPOTHESIS: The TCA cycle rate will be lower in FRDA subjects than in controls APPROACH: The investigators will infuse carbon-13 (13C) labeled glucose and measure the rate of 13C label incorporation from glucose to glutamate in the brain using in vivo magnetic resonance spectroscopy.
Neurodegenerative cerebellar ataxias represent a group of disabling disorders for which we currently lack effective therapies. Cerebellar transcranial direct current stimulation (tDCS) is a non-invasive technique, which has been demonstrated to modulate cerebellar excitability and improve symptoms in patients with cerebellar ataxias. In this randomized, double-blind, sham-controlled study, the investigators will evaluate whether a two-weeks' treatment with cerebellar anodal tDCS and spinal cathodal tDCS can improve symptoms in patients with neurodegenerative cerebellar ataxia and can modulate cerebello-motor connectivity, at short and long term.
Children with Developmental Coordination Disorder (DCD) have difficulties performing daily activities which reflects negatively on participation, impacting their lives. To date, there are a number of interventions to improve performance of these children on activities they want or need to. In Brazil, there is little research on the efficacy of such approaches. Our main objective was to start a set of studies to examine the effects of the Cognitive Orientation to Daily Occupational Performance Approach (CO-OP Approach) protocol on occupational performance and satisfaction of Brazilian children who have DCD; to examine whether children were able to transfer strategies and skills learned during CO-OP to untrained goals.
The project will study a therapeutic approach in Spinocerebellar Ataxia (SCA38) by DHA replacement. SCA38 is caused by missense mutations in the ELOVL5 (Elongation of very long chain fatty acids protein 5) gene. Background/Rationale: ELOVL5 is a microsomal fatty acid elongase gene required for the synthesis of arachidonic acid and DHA. In brain, it shows a peculiar high expression in cerebellar Purkinje cells. The ELOVL5 products, such as DHA, are decreased in SCA38 patients serum and DHA administered as a dietary supplement has been shown to improve SARA scores, to ameliorate quality of life, and to increase brain cerebellar hypometabolism (FDG-PET) in two SCA38 patients. Experimental Plan: The investigators will perform a randomized placebo-controlled trial by DHA supplementation on ten SCA38 patients, followed by an open-label phase. Expected results: DHA supplementation should be able to improve symptoms in SCA38 and to improve cerebellar hypometabolism in these patients.
This multicenter natural history study aims to expand the network of clinical research centers in FA, and to provide a framework for facilitating therapeutic interventions. In addition, this study will lead to the development of valid yet sensitive clinical measures crucial to outcome assessment of patients with Friedreich's Ataxia. This study will support genetic modifier studies, biomarker studies, and frataxin protein level assessments by building a sample repository.
To investigate the effects of whole body vibration on postural control and on the level of satisfaction regarding how to reach the goals of the patients with ataxia
The objective of this research is to study the sphincter activity during ejaculation in patients with spinal cord injury in order to detect an ejaculatory dyssynergia. For this purpose, using a catheter the protocol plans to measure the sphincter pressures during ejaculation. Moreover, cardiovascular parameters will be measured continuously during the ejaculatory test.
The primary purpose of this study is to compare the efficacy of BHV-4157 (Troriluzole) 140 milligrams (mg) once daily versus placebo after 8 weeks of treatment in subjects with spinocerebellar ataxia (SCA).
In this study the investigators aim to identify and characterize a potential neurophysiological biomarker by mapping functional networks of brain activity (Brain Network Activation, BNA) based on analysis of evoked response potential (ERP) signals in both asymptomatic FMR1 premutation carriers and in patients with various stages of FXTAS. Additionally correlations will be studied between these BNA scores and demographics (gender, age and disease duration) as well as genetic mutation and clinical scores.
