Spontaneous oro-facial chorea is a disorder manifested by repetitive unintentional choreic movements of the face which are usually most prominent around the mouth. It is to be distinguished from cephalic dystonia (Meige’s or Breughel’s syndrome) in which the movements are of longer duration, have a greater tendency to involve the upper face, and usually are much more distressing to the patient. This latter condition is discussed in Chapter 37. Some of the movements of spontaneous oro-facial chorea may be repetitive, patterned, and hence appear as stereotypies (see below under ‘Tardive dyskinesia’). Some have expressed the view that the majority of spontaneous late onset edentulous dyskinesias are actually a form of idiopathic torsion dystonia (Jankovic 1988, Jankovic and Fahn 1993), but the disability and appearance in this group of patients tends to be different from that seen in Meige’s syndrome, so we have chosen to retain the term oro-facial chorea. Tardive dyskinesia is an involuntary movement disorder which is due to prolonged administration of neuroleptic and other drugs. The commonest manifestation of this disorder is oro-facial chorea, similar, if not identical, to the spontaneously occurring variety.
