View clinical trials related to Hereditary Ataxia.
Filter by:The hereditary ataxias are a group of genetic disorders characterized by slowly progressive incoordination of gait and balance impairments in sitting and standing. Trunk local stability during gait is lower in patients with degenerative ataxia than that in healthy adult population. Given the fact that drug interventions are rare in degenerative diseases and limited to only specific type of diseases and symptoms, physiotherapy is a major cornerstone in current therapy of ataxic gait. Core stability exercises training could be included as an adjunct to conventional balance training in improving dynamic balance and gait. Due to the nature of the interventions, the study will have a single blind design.
Cerebellar disorders are often disabling and symptomatic therapies are limited to few options that are partially effective. It seems therefore appropriate to search for additional approaches. Purkinje cells are the sole output of the cerebellar cortex: they project inhibitory signals to the deep cerebellar nuclei (DCN), which have a critical role in cerebellar function and motor performance. DCN neurons fire spontaneously in the absence of synaptic input from Purkinje neurons and modulation of the DCN response by Purkinje input is believed to be responsible for coordination of movement. Recent evidences support the notion that an increase in DCN excitability may be an important step in the development of cerebellar ataxia and point to the underlying molecular mechanisms: the inhibition of small-conductance calcium-activated potassium (SK) channels, that causes an increase of the firing frequency in DCN, correlates with cerebellar ataxia. The rationale of the present project is that SK channel openers, such as riluzole, may have a beneficial effect on cerebellar ataxia. The researchers propose to perform a pilot study investigating safety and efficacy of riluzole, an approved treatment for amyotrophic lateral sclerosis, as a symptomatic approach in patients with chronic cerebellar ataxia.
OBJECTIVES: I. Clinically evaluate members from families with a dominantly inherited ataxia and collect blood, skin and muscle samples for detailed molecular studies. II. Perform detailed clinical evaluations on patients with recessively inherited ataxias.
