Webisolated focal cortical dysplasia is a rare, genetic, non-syndromic cerebral malformation due to abnormal neuronal migration disorder characterized by variable-sized, focalized malformations located in any part (s) of the cerebral cortex, which manifests with drug-resistant epilepsy (usually leading to intellectual disability) and behavioral The expectation of life in patients with cortical dysplasia vary from patient to patient.
