Congenital bilateral perisylvian polymicrogyria syndrome (CBPS) has a cerebral cortical localization and its phenotype was thought to be purely central. This study of seven children with CBPS (five males, two females; mean age 5 y [SD 3 y 6 mo]; range 1 mo-11 y 10 mo) documents electrophysiological evidence of lower motor neuron involvement in association with congenital contractures (limb or jaw) in six of the seven children studied. This is not an expected association and does not conform to the traditional lesional classification system of the cerebral palsies. Possible pathogenic mechanisms are discussed but this association of upper and lower motor neuron involvement is likely to be a previously unsuspected part of a genetic or other pathogenic sequence.

D002658	Developmental Disabilities	Disorders in which there is a delay in development based on that expected for a given age level or stage of development. These impairments or disabilities originate before age 18, may be expected to continue indefinitely, and constitute a substantial impairment. Biological and nonbiological factors are involved in these disorders.
