What is sensory ataxia?

Sensory Ataxia (SA) is a form of ataxia caused by the impairment of the somatosensory nerves, leading to the interruption of sensory feedback signals. It is characterized by postural instability and lack of coordination that worsen when visual input is removed.


What is an example of sensory ataxia?

An example of this is how you know where your hands and feet are, even if you can't see them (such as with your eyes closed or in a dark room). Sensory ataxia disrupts your self-positioning sense. Vestibular: This type involves a problem with your inner ears, which are part of your sense of balance.

What are the symptoms of sensory ataxia?

Symptoms may include:
  • Poor coordination.
  • Walking unsteadily or with the feet set wide apart.
  • Poor balance.
  • Trouble with fine motor tasks such as eating, writing or buttoning a shirt.
  • Changes in speech.
  • Back-and-forth eye movements that can't be controlled.
  • Trouble swallowing.


What is the difference between ataxia and sensory ataxia?

Sensory ataxia is caused by the impairment of somatosensory nerve, which leads to the interruption of sensory feedback signals and therefore, the body incoordination is caused. For Cerebellar Ataxia patients, the Romberg's sign was positive, the typical symptoms include walking slowly, rolling, etc.

How do you test for sensory ataxia?

An MRI of the brain might help find the possible causes. An MRI can sometimes show shrinkage of the cerebellum and other brain structures in people with ataxia. It also may show other treatable findings, such as a blood clot or benign tumor. A spinal tap, also known as lumbar puncture.

What is another name for sensory ataxia?

Ataxia neuropathy spectrum now includes the conditions previously called mitochondrial recessive ataxia syndrome (MIRAS) and sensory ataxia neuropathy dysarthria and ophthalmoplegia (SANDO).

What are the first signs of ataxia?

The most common symptoms include:
  • Balance and movement problems (affected first)
  • Poor movement of hands, arms, and legs.
  • Slurring of speech.
  • Wide-based gait when walking.
  • Trouble writing and eating.

  • Falls.


How is sensory ataxia treated?

If you have ataxia, physiotherapy can help you maintain the use of your arms and legs, and prevent your muscles weakening or getting stuck in one position (contractures). A physiotherapist will be able to teach you a number of physical exercises you can do every day to help strengthen and stretch your muscles.


What vitamin deficiency causes ataxia?

A shortage (deficiency) of vitamin E can lead to neurological problems, such as difficulty coordinating movements (ataxia) and speech (dysarthria), loss of reflexes in the legs (lower limb areflexia), and a loss of sensation in the extremities (peripheral neuropathy).

Is sensory ataxia a form of neuropathy?

As the name implies, people with ataxia neuropathy spectrum typically have problems with coordination and balance (ataxia) and disturbances in nerve function (neuropathy). The neuropathy can be classified as sensory, motor, or a combination of the two (mixed).

What is the prognosis for sensory ataxia?

The prognosis largely depends on the type and cause of ataxia. Patients with progressive ataxia may suffer from worsening symptoms over the years and require symptomatic treatment. Hereditary ataxia has a shorter life expectancy; however, some people live up to the fifth or sixth decade.


Can you drive with sensory ataxia?

This does not automatically mean you have to stop driving. For some people with ataxia, their condition means they need adaptations to their car to carry on driving and eventually may decide to give up driving. For more information on this, contact the DVLA.

  • Phenytoin – May cause nystagmus at therapeutic doses, but ataxia is common at supratherapeutic levels. ...
  • Valproic acid – May cause cerebellar ataxia in the setting of hyperammonemia.
  • Benzodiazepines – Most commonly described in children with epilepsy.

What are the first signs of sensory ataxia?

Sensory ataxia is mainly reflected by gait disturbance. Subjects with sensory ataxia will have a positive Romberg sign. Subjects may walk with a high-stepping gait (due to associated motor weakness) or feet-slapping gait (to assist with sound-induced sensory feedback).

Does ataxia show up on MRI?

Brain scans: Magnetic resonance imaging (MRI) brain scans can give an image of the cerebellum and other parts of the brain that show whether they are damaged. The scans can sometimes be used to distinguish between multiple sclerosis and ataxia.


Is sensory ataxia a degenerative condition?

Ataxia is a a degenerative disease of the nervous system that causes abnormal and uncoordinated movements. Ataxia can be acquired by damage to the cerebellum, the spinal cord and other nerves. It can also be a hereditary complication which you inherit from your family genetics.

What disease makes you lose the ability to walk?

Other nerve conditions can suddenly affect ability to walk such as Guillain-Barré syndrome (a disorder where the immune system attacks the nerves), multiple sclerosis flares, or compressed nerves in the spine.

Is brain fog a symptom of ataxia?

During this time balance and coordination begin to deteriorate. Those affected may also experience involuntary movements and tremors. In addition to the physical symptoms, there are other invisible and often less tangible symptoms such as fatigue and brain fog.


At what age does ataxia start?

Hereditary ataxia

Symptoms will normally start before the age of 25 but they can develop later. Spinocerebellar ataxia (SCA's) are caused by mutations in different genes. More than 100 types of SCA's have been found through research since 1965. Ataxia with oculomotor apraxia (AOA) comes in 2 forms AOA1 or AOA2.
