title: Choreiform movements induced by anticholinergic therapy.
abstract: A case is reported where long term therapy with anticholinergic drugs caused choreiform movements in a 73-year-old man. After the therapy was ceased the movements disappeared. The elderly are particularly at risk from developing side effects from drug therapy. We believe this to be the first report of chorea produced by long-term therapy with benzhexol.
