Cortical dysplasia; other clinical presentations  Dysplasia involving extratemporal regions demonstrates earlier age at presentation, more severe epilepsy, higher incidence of mental retardation and developmental delay. 21. [slideshare.net]

Although focal cortical dysplasia is a congenital malformation and present at birth, the patient may not develop epilepsy until childhood, adolescence, or adulthood. [rscdiagnosticservices.com]

This requires extensive workup with detailed brain imaging and EEGs. A neurosurgeon will then surgically remove the area of the brain that is causing the seizures. This is called epilepsy surgery. [childneurologyfoundation.org]

Treatments may lessen or alleviate seizures and improve the quality of life for HME patients. [hemifoundation.homestead.com]

What are the Treatments? The treatment is based on controlling the seizures. Focal seizures with identified focal cortical dysplasia can be very difficult to control with antiepileptic medications. [rscdiagnosticservices.com]

PROGNOSIS What is the outcome with treatment? About 60 to 70% of children will stop having seizures after treatment with one AED. Response to therapy depends a great deal on the seizure type and the cause for the epilepsy. [childneurologyfoundation.org]
