  • A videotape accompanies this article.


We describe a 71-year-old woman who presented to the neurology department late in life with a jerky axial dystonia due to the DYT1 GAG deletion. She recalled that her symptoms began 62 years prior to study and remained unchanged for 40 years, illustrating the broad phenotype of DYT1 idiopathic torsion dystonia. © 2001 Movement Disorder Society.
