Causes

Cerebellum is a part of brain that is involved in the muscles control and coordination. Any damage, trauma or loss of nerve tissue result in its failure of function. Two portions of folded tissues which are the part of cerebellum attached to the base of the brain stem that help in controlling eye movement and swallowing. Some major causes of ataxia are:

  • Traumatic injury to the head
  • Stroke occurring due to blockage of blood vessels or bleeding in the brain
  • Cerebral palsy

  • Vitamin E, B12 and thiamine deficiency
  • Covid-19 infection
  • It can occur due to some genetic mutation. Different types of mutation causes different types of ataxia. Some of them are spinocerebellar ataxia, episodic ataxia, Friedreich’s ataxia, Ataxia-telangiectasia, Congenital cerebellar ataxia, Wilson’s disease.
Diagnosis

Diagnosis of this condition depends upon complete history and general physical examination of patient. Other laboratory investigations include:

  • CT scan
  • MRI
  • Spinal tap or lumber puncture
  • Genetic testing
Treatment

Treatment of ataxia is not known till now. Some adaptive devices are used to manage this condition like:

  • Hicking sticks and walkers or communication aid for speaking.
