Central bilateral macrogyria (rolandic and perisylvian) is a neuronal migration disorder with characteristics of pseudobulbar palsy, developmental delay, mild intellectual disability and epilepsy. It has been described in at least four children. Is a True Macrogyria Inferred relationship Some
A rare, genetic neurological disorder characterized by the presence of diffuse pachygyria and arachnoid cysts, psychomotor developmental delay and intellectual disability. Seizures (absence, atonic and generalized tonic-clonic) and, on occasion, headache are also associated. Is a True Macrogyria Inferred relationship Some
A cerebral malformation characterized by symmetric, bilateral pachygyria with normal head circumference and without polymicrogyria. Clinical manifestations include developmental delay, moderate intellectual disability, normal or slightly decreased muscle tone and deep-tendon reflexes, telecanthus or hypertelorism. Is a True Macrogyria Inferred relationship Some
A rare, genetic, cerebral malformation characterized by the presence of cortical smoothening with loss of secondary and tertiary gyri, associated with an excessive number of small, irregular gyri with increased cortical thickness, located in the occipital lobes. Patients usually present with seizures (including myoclonic-astatic, absence, atypical absence, vision loss, myoclonic-atonic, generalized tonic-clonic) and variable (absent to moderate) developmental and/or intellectual delay. Is a True Macrogyria Inferred relationship Some
A rare genetic syndrome with a central nervous system malformation as a major feature, characterized by cortical malformations including posterior predominant lissencephaly and diffuse pachygyria, as well as midline crossing defects, thin corpus callosum, dysplastic hippocampi, narrowing of the brainstem with small pons and midbrain, widening of the medulla, and small cerebellum. Clinically, patients present global developmental delay, severe intellectual disability with poor or absent speech, axial hypotonia, and early-onset seizures, among others.
