The most common clinical presentation is intractable seizures. Heterotopia present as nodular foci of grey matter intensity on all sequences. They do not enhance. Heterotopia Images of a typical subependymal heterotopia. [radiologyassistant.nl]

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]

Patients usually present with intractable seizures. [ajnr.org]

The clinical presentation is related to the association with either schizencephaly (presenting with seizures) or hypothalamic and pituitary hypoplasia (presenting with pituitary insufficiency). [mrineonatalbrain.com]

• Disability

  genetic, non-syndromic cerebral malformation due to abnormal neuronal migration disease characterized by the association of cortical dysplasia and pontocerebellar hypoplasia, manifesting with global developmental delay, mild to severe intellectual disability [malacards.org]

  In addition, we report 1 individual with macrocephaly and intellectual disability without seizures. [ng.neurology.org]

  Abnormal cortical development is increasingly recognized as a cause of developmental disabilities and epilepsy. [karger.com]

• Aggressive Behavior

  Seizures from the cingulate gyrus can involve screaming, aggressive behavior, and feelings of intense fear. The heart and breathing rate may rise, and sweating and pallor can also occur. [childneurologyfoundation.org]

• Opisthotonus

   Early hypotonia, later spastic quadriplegia and opisthotonus. 8. Subcortical band heterotopia-Double cortex Sub-cortical, symmetric, circumferential bands of gray matter, separated from cortex by thin band of white matter. [slideshare.net]

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]

Your doctor will then talk with you about a few other treatment options. What other treatment options are there? Epilepsy surgery, vagus nerve stimulator (VNS), and ketogenic diet are some treatment options available if medications have failed. [childneurologyfoundation.org]

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]
