Metabolic disorders arise when the body fails to process the chemicals in the body properly. This can result in excesses or deficiencies of materials arising in different parts of the body. Dystonia is one of the conditions that can occur when these metabolic disorders affect the brain. There are more than 50 different metabolic conditions that can cause dystonia but most of them are extremely rare.

Examples include Wilson’s disease which is a treatable genetic condition in which the body does not process copper properly and neuronal brain iron accumulation syndrome (NBIA) – a genetic degenerative condition in which iron is deposited in the basal ganglia.
