Hemidystonia
Hemidystonia
Hemidystonia is dystonia affecting the whole of one side of the body, a pattern which mandates structural brain imaging because of the chance of finding a causative structural lesion (vascular, neoplastic), which is greater than with other patterns of dystonia (focal, segmental, multifocal, generalized). Such a lesion most often affects the contralateral putamen or its afferent or efferent connections.
