[Bucco-linquo-facial and choriform hyperkinesies (author's transl)].

These bucco-linguo-facial and choriform hyperkinesies still remain all too frequent in many neurological diseases. The authors study exclusively the dyskinesies of essential origin or iatrogenous including the post neuroleptic and post dopatherapy dyskinesies. All the neuroleptics can be involved at different stages of the treatment, giving rise to difficulties in the diagnosis. Dopatherapy in the Parkinson disease is also responsable of many dyskinesias. Time of appearance after the drug's taking, significance and treatment are discussed. The idiopathic dyskinesis are more unusual either with the some only facial involvement, or in association with another abnormal movements. The physiopathology is doubtful, so the treatment is often very difficult.
