GHB accumulates in the nervous system and can cause ataxia as well as other neurological dysfunction. Top of the page – Article Outline. The movement disorders associated with ataxia can be managed by pharmacological treatments and through physical therapy and occupational therapy to reduce disability.

Wilson’s disease is an autosomal – recessive gene disorder whereby an alteration of the ATP7B gene results in an inability to properly excrete copper from the body. The cerebellum is responsible for integrating a significant amount of neural information that is used to coordinate smoothly ongoing movements and to participate in motor planning. This agaxie is empty. Retrieved 09 Marchfrom Dictionary. Malfunction of the sodium-potassium pump may be a factor in some ataxias. These include reversible cerebellar ataxiadementiaperipheral neuropathypsychosis and lroprioceptive.

Retrieved 7 May Optic ataxia may be caused by lesions to the posterior parietal cortex, which is responsible for combining and expressing positional information and relating it to movement.

Parry cA. Vitamin B 12 deficiency may cause, among several neurological abnormalities, overlapping cerebellar and sensory ataxia. Most of the neurological complications improve completely after thyroid hormone replacement therapy.


Routine clinical testing underestimates proprioceptive deficits in Friedreich’s ataxia.

Frontiers in Behavioral Neuroscience. It consists of a downward displacement of the cerebellar tonsils and the medulla through the foramen magnumsometimes causing hydrocephalus as a result of obstruction of cerebrospinal fluid outflow.

Friedreich’s ataxia has gait abnormality as the most commonly presented symptom. Clinical and pharmacological considerations prkprioceptive treatment”. These torques increase as the speed of movement increases and must be compensated and adjusted for to create coordinated movement.

Optic ataxia is not only ‘optic’: impaired spatial integration of proprioceptive information.

Cerebellar ataxia can have many causes despite normal neuroimaging. These tests include, but are not limited to:.

Hereditary disorders causing ataxia include autosomal dominant ones such as spinocerebellar ataxiaepisodic ataxiaand dentatorubropallidoluysian atrophyas well as autosomal recessive disorders such as Friedreich’s ataxia sensory and cerebellar, with proprioceptuve former predominating and Niemann Pick diseaseataxia-telangiectasia sensory and cerebellar, with the latter predominatingand abetalipoproteinaemia.

Here, we specifically investigated the capacity of two patients with unilateral optic ataxia in tasks requiring different levels of proprioceptive integration from primary information processing to proprioceptivo-motor integration.

Ataxia – Wikipedia

Archived from the original on 18 March Journal of Clinical and Diagnostic Research. Archived from proprioceptige original on 8 May These outcomes include balance tasks, gait, and individual activities of daily living.

Spinal disorders of various types may cause sensory ataxia from the lesioned level below, when they involve the dorsal columns. Ataxia is a clinical manifestation indicating dysfunction of the parts of the nervous system that coordinate movement, such as the cerebellum. Worsening of the finger-pointing test with the eyes closed is another feature of sensory ataxia.


Optic ataxia is not only ‘optic’: impaired spatial integration of proprioceptive information.

The term “ataxia” is sometimes used in a broader sense to indicate lack of coordination in some physiological process. Optic ataxia is usually part of Balint’s syndromebut can be seen in isolation with injuries to the superior parietal lobule, as it represents a disconnection between visual-association cortex and the frontal premotor and motor cortex.

The term cerebellar ataxia is used to indicate ataxia that is due to dysfunction of the cerebellum. Journal page Archives Contents atsxie. The term sensory ataxia is employed to indicate ataxia due to loss of proprioceptionthe loss of sensitivity to the positions of joint and body parts.
