Abstract. Paroxysmal choreoathetosis is a rare, involuntary movement disorder. Attacks occur spontaneously or may be induced by movement, startle, or anxiety. The movements are tonic, dystonic, or choreoathetotic. Sporadic and, more commonly, familial cases have been reported. Onset occurs most often during childhood, and the course is nonprogressive. Response to anticonvulsant therapy is usually excellent. Five cases of the sporadic form of paroxysmal choreoathetosis are reported. Three of the five patients had attacks after initiation of movements such as rising from a chair. Results of physical examination were normal in four patients. One child had mild hemiatrophy and unilateral hyper-reflexia. Results of laboratory studies, including determinations of serum calcium and ceruloplasmin levels, EEGs, and CAT scans of the head, were normal. The attacks ceased in all patients after treatment with either phenytoin or carbamazepine. [ABSTRACT FROM AUTHOR]

Abstract. Psychogenic seizures in 21 nonepileptic children and adolescents, aged 8 to 18 (mean 14.5) years, were recorded by means of video recording and electroencephalography. The episodes included thrashing movements, limb jerking, or staring, with unresponsiveness. Ictal and interictal electroencephalograms showed no abnormalities after antiepileptic medication was discontinued. Fifteen patients had psychogenic seizures spontaneously during recording, and six had seizures in response to suggestion and intravenous saline injection. After the video-electroencephalographic evaluation, patients and families were told that the episodes were emotional in origin. All patients but I agreed to remain without antiepileptic medication, and 16 patients (76%) agreed to begin psychiatric treatment. At 6 to 66 (mean 30) months' follow-up, 14 of 18 (78%) were free of episodes. These data indicate that the majority of young patients with psychogenic seizures have a good outcome. A firm diagnosis is critical so that the episodes can be classified and emphasized as medically not worrisome, permitting a shift away from antiepileptic medication and toward psychiatric treatment.
