title: Familial and genetic associations in Worster-Drought syndrome and perisylvian disorders.
abstract: Worster-Drought syndrome (WDS) is a distinct clinical phenotype, comprising a congenital pseudobulbar palsy usually in association with a mild tetraplegia and often additional impairments. The phenotype is identical to that described in congenital bilateral perisylvian polymicrogyria syndrome (CBPS) and appears to have several different causes and a significant familial incidence. This study draws from a database of children with WDS phenotype or perisylvian polymicrogyria, held at a tertiary center. The findings suggest that genetic factors are important for a significant proportion of children and points to considerable genetic heterogeneity. There are grounds for considering WDS and perisylvian polymicrogyria as a spectrum of perisylvian malfunction.
