Paroxysmal kinesigenic dyskinesia with infantile convulsions (PKD/IC) is an episodic movement disorder with autosomal-dominant inheritance and high penetrance, but the causative genetic mutation is unknown. We have now identified four truncating mutations involving the gene PRRT2 in the vast majority (24/25) of well-characterized families with PKD/IC. PRRT2(More)
We have studied one family of Chinese origin, in which benign infantile convulsions and paroxysmal choreoathetosis (of the dystonic form) were co-inherited as a single autosomal dominant trait. This association is specific to ICCA syndrome, which we have recently described in four French families. Some patients in the new family also exhibit recurrence of(More)
This study aimed to demonstrate that afebrile seizures provoked by minor infections constitute a distinct epilepsy syndrome different from febrile seizures and unprovoked afebrile seizures. Of the children who were admitted to hospitals for their first seizure, 1170 had febrile seizures, 286 had provoked seizures, and 125 had unprovoked afebrile seizures.(More)
Neuropsychiatry is an emerging field at the intersection of neurology and psychiatry, driven by the unprecedented advances in neuroscience. The arbitrary demarcation between neurology and psychiatry, which largely existed only in the last century and a half, has become less tenable. We discuss the definition and scope of this emerging field. We also review(More)
The rare variant A673T in the amyloid-β precursor protein (APP) gene has been shown to reduce the risk of cognitive impairment. We genotyped the variant in 8721 Asian individuals comprising 552 with Alzheimer's disease and vascular dementia, 790 with Parkinson's disease, and 7379 controls. The A673T variant was absent in all of the subjects. Our finding(More)
