What Are the Different Types of Ataxia?

Ataxia describes a lack of voluntary coordination of muscle movements including walking, picking up objects, speaking, swallowing and eye movements.

According to the causes of the disease, ataxia can be divided into hereditary ataxias,
autosomal dominant ataxias including spinocerebellar ataxias, and episodic ataxia (EA), autosomal recessive ataxias including Friedreich’s ataxia, ataxia-telangiectasia, and congenital cerebellar ataxia.

According to the effects of the disease, ataxia can be divided into cerebellar ataxia, sensory ataxia, and vestibular ataxia.

Cerebellar ataxia refers to the ataxia due to dysfunction of the cerebellum. There are three common causes of cerebellar ataxia including dysfunction of the vestibulocerebellum, dysfunction of the spinocerebellum, and dysfunction of the cerebrocerebellum.

Sensory ataxia refers to the ataxia because of the loss of proprioception and the loss of sensitivity to the positions of joint and body parts. The causes of sensory ataxia include dysfunction of the dorsal columns of the spinal cord, and dysfunction of the various parts of the brain.

Vestibular ataxia refers to the ataxia due to dysfunction of the vestibular system. Its possible signs include prominent vomiting, nausea and vertigo.
