Stereotyped hand clasping: An unusual tardive movement disorder



We report an 83-year-old woman with vascular parkinsonism who presented with stereotyped rhythmical hand-clasping movements after 18 months exposure to neuroleptics. Although stereotypical rhythmical orolinguomasticatory and limb movements are the most common tardive dyskinesia in the elderly, we feel this woman's hand clasping represents another unusual expression of a tardive movement disorder.
