Filter by:To produce hand's movement directed towards a target, the investigator must combine several sensory information, such as vision or proprioception. The posterior parietal cortex (PPC) is a region of the cortex involved in this multisensory integration. A lesion of the PPC cause a visuo-motor trouble called optic ataxia but these patients also have perceptual troubles. The aim of the study is to understand the different functions of the PPC and especially how the processes of spatial coding of the sensory information influences perception and motor planning. In this study, the investigator want to explore the sensory motor and the perceptual performance of patients with optic ataxia compared with healthy subjects, using 6 behavioral tests. Objectify the consequences of PPC impairment (visual-motor and perceptual consequences) on patients' quality of life and autonomy.
The diagnosis and management of movement disorders, such as Parkinson's disease (PD), parkinson-plus syndromes (PPS), dystonia, essential tremor (ET), normal pressure hydrocephalus (NPH) and others is challenging given the lack of objective diagnostic and monitoring tools with high sensitivity and specificity. A cornerstone in research of neurological disorders manifesting as MDi is the investigation of neurophysiological changes as potential biomarkers that could help in diagnosis, monitoring disease progression and response to therapies. Such a neuro-marker that would overcome the major disadvantages of clinical questionnaires and rating scales (such as the Unified Parkinson's disease rating scale -UPDRS, for PD, The Essential Tremor Rating Assessment Scale -TETRAS, for ET and others), including low test-retest repeatability and subjective judgment of different raters, would have real impact on disease diagnosis and choice of interventions and monitoring of effects of novel therapeutics, including disease modifying therapies. To address this, ElMindA has developed over the last decade a non-invasive, low-cost technology named Brain Network Activation (BNA), which is a new imaging approach that can detect changes in brain activity and functional connectivity. Results from proof-of concept studies on PD patients have demonstrated that: 1) PD patients exhibited a significant decrease in BNA scores relatively to healthy controls; 2) notable changes in functional network activity in correlation with different dopamine-agonist doses; 3) significant correlation between BNA score and the UPDRS). 4) BNA could also differentiate early PD from healthy controls
The purpose of this study is to evaluate the efficacy of TAK-831 versus placebo on upper extremity (arm and hands) motor function and manual dexterity. This study will also evaluate the efficacy of TAK-831 versus placebo on activities of daily living (ADL) and other secondary assessments.
Cerebellar ataxias are a group of disorders caused by cerebellar affections, for which currently no specific treatment is available. Some limited studies verified the effects of cerebellar transcranial magnetic stimulation (TMS) on ataxic symptoms, with good results. So far it is not known which patients could benefit. Our hypothesis is that cerebellar TMS could improve ataxic symptoms in some patients.
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.
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.
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).
Genetic cerebellar ataxias involves progressive degeneration of the cerebellum. Their overall prevalence is estimated at 2-4 cases per 100 000 people. These diseases are manifested by a static and kinetic cerebellar syndrome characterized by impaired balance, coordination, and an ataxic gait. To date, no therapy is available for patients and physical therapy is essential and recommended. The evolution of the pathology causes a degradation of walking, increased instability and risk of falling. In one year, between 74% and 93% of patients reported having fallen at least once. Falls prevention by understanding the mechanisms affecting stability is a major issue in the management of these patients physiotherapy. The analysis of the literature, we assume that there exists a trio "fatigue - instability - energy expenditure" in which the three parameters would influence each other. To date, we do not have data to characterize these interrelationships and their evolution over time. STUDY OBJECTIVES: The main objective is to study the relationship between changes in energy expenditure and changes in instability when walking at one year in patients with cerebellar ataxia gene. The secondary objectives are to study, after one year of development, the relationship between fatigue, instability, energy consumption, the number of falls, the severity of ataxia and quality of life. CONDUCT OF THE STUDY: This is a pilot, multicenter, interventional. The projected duration of patient recruitment will be 12 months and the total number of patients will be included in 15. The duration of participation in this study is 12 months for each patient. The anticipated duration of the study is 30 months. Development of the study: Patients included will perform two sets (S1 and S2) tests a year apart including the evaluation of ataxia according Scale for the assessment and rating of ataxia (SARA); measuring the quality of life through SF36 (The Short Form (36)) Questionnaire; quantifying the severity of fatigue perceived by FSS questionnaire quantifying the severity of physical tiredness by VAS before and after physical activity; quantified analysis of walking on walking track GAITRite® (with score calculation FAP and GVI) before and after physical activity; physical activity like walking on a treadmill (with measurement of maximal voluntary quadriceps by manual dynamometer before and after physical activity to ensure the induction of fatigue). Patients will be provided with a portable device for analyzing gas exchange FitMateMED® (COSMED, Rome, Italy) during walking analyzes GAITRite®.
