Dystonia: Causes

The exact cause of dystonia isn’t known. But it might involve altered nerve-cell communication in several regions of the brain. Some forms of dystonia are inherited.

Dystonia also can be a symptom of another disease or condition, including:

  • Parkinson’s disease
  • Huntington’s disease
  • Wilson’s disease
  • Traumatic brain injury
  • Birth injury
  • Stroke
  • Brain tumor or certain disorders that develop in some people with cancer (paraneoplastic syndromes)
  • Oxygen deprivation or carbon monoxide poisoning
  • Infections, such as tuberculosis or encephalitis
  • Reactions to certain medications or heavy metal poisoning
