Alien hand sign after a right parietal infarction.

Involuntary movements are unusual during or after acute stroke, and alien hand sign has not been reported after single parietal infarction. We report on a woman who presented with involuntary movements and a sense of alienness of her left upper limb following a right parietal infarction. This combination, that can meet the criteria for the 'alien hand syndrome', is rarely seen after acute lesions sparing the corpus callosum and the mesial frontal areas. Copyright 2000 S.
