Ataxia is a neurological symptom chracterized by gross incoordination of muscle movements usually caused by damage to parts of the brain or central nervous system which coordinate movement. There are several possible causes for the condition ranging from physical injury, disease, stroke, tumours, substance abuse, hereditary factors[1] and vitamin deficiency[2].
"International Ataxia Awareness Day" is held on September 25th each year.
Types of ataxia
Cerebellar ataxia
The term cerebellar ataxia is used to describe ataxia due to dysfunction of the cerebellum.
Sensory ataxia
The term sensory ataxia is used to describe ataxia due to loss of proprioception (sensitivity to joint and body part position).
Vestibular ataxia
The term vestibular ataxia is used to describe ataxia due to dysfunction of the vestibular or balance system, which in acute and unilateral cases may be associated with vertigo, nausea and vomiting.
