title: Generalised dystonia with an abnormal magnetic resonance imaging signal in the basal ganglia: a case of adult-onset GM1 gangliosidosis.
abstract: We describe a 46-year-old woman with adult-onset generalised dystonia and a severe speech disorder with an abnormal magnetic resonance imaging signal in the basal ganglia. A storage disease study demonstrated the presence of a GM1 gangliosidosis. This rare condition should be investigated in cases of generalised dystonia, especially in those cases with other features suggesting symptomatic dystonia.
