If the cortical dysplasia got severe in children then the expectation of life is very less as it is very difficult to treat cortical dysplasia in the mothers womb. This type normally involves both the temporal and frontal lobe of the brain.

These are localised regions of malformed cerebral cortex and are frequently associated with epilepsy in children and adults. Focal cortical dysplasias (FCD) represent a heterogeneous group of disorders of cortical formation, which may demonstrate both architectural and proliferative features. Dr. Bartolini is one of only a handful of pediatric epilepsy specialists with expertise in the complex evaluation leading to surgery and in reading invasive EEGs.
