    General Discussion
    Congenital Bilateral Perisylvian Syndrome (CBPS) is an extremely rare neurological disorder that may be apparent at birth (congenital), infancy, or later during childhood. It is characterized by partial paralysis of muscles on both sides (diplegia) of the face, tongue, jaws, and throat (pseudobulbar palsy); difficulties in speaking (dysarthria), chewing (mastication), and swallowing (dysphagia); and/or sudden episodes of uncontrolled electrical activity in the brain (epilepsy). In most cases, mild to severe mental retardation is also present. Associated symptoms and findings are thought to be due to improper development of the outer surface of the brain (cerebral cortex) during embryonic growth (neuronal dysmigration). In most cases, the disorder appears to occur randomly for unknown reasons (sporadically).
