Definition

The term dystonia is used in several different contexts:
1) To describe an abnormal hyperkinetic movement characterised by sustained involuntary muscle contraction
2) As a syndromic diagnosis in which dystonia occurs in relative isolation

When dystonia occurs in relative isolation, it may or may not be possible to attribute an underlying cause such as a causative genetic variant.

A number of neurological disorders can cause dystonia and in these cases the dystonia occurs in the context of the clinical features of the other disorder (e.g. Parkinson's disease). The syndrome in these causes is referred to a combined dystonia.
