Causes

By Mayo Clinic staff

Doctors don't know exactly what causes most cases of dystonia, but a few factors may be involved.

Altered nerve cell communication
Dystonia has been linked to altered communication between nerve cells located in the basal ganglia — an area of the brain involved in initiating muscle contractions.

Genetic changes
Researchers have also discovered a number of genetic changes associated with certain inherited forms of dystonia and also with other forms of dystonia. However, most cases of adult-onset focal dystonias have not been linked to genes.

Other disorders
Sometimes dystonia is but one symptom of a more pervasive disorder that affects the basal ganglia, such as:

  • Parkinson's disease
  • Huntington's disease
  • Traumatic brain injury
  • Stroke
  • Brain tumor
  • Oxygen deprivation
  • Infections, such as tuberculosis or encephalitis
  • Reactions to certain drugs
  • Heavy metal or carbon monoxide poisoning
