[Abnormal movements in children. 2 cases of known etiology but infrequent: Sandifer syndrome and a syndrome caused by neuroleptics].

Authors present two cases of children with abnormal movements. One of them described slow and dystonic movements of neck and head due to an important gastroesophageal reflux. These movements were useful to decrease annoyances that reflux causes in the child. Appearance of these movements and reflux is what is named "Sandifer syndrome". The other case presented stereotyped movements of head, like a negation, continuous and produced by a long intake of neuroleptics, which had caused a blockade of central dopaminergic receivers. Suppression neuroleptics of cured the child.
