    General Discussion
    Hemimegalencephaly is a rare neurological condition in which one-half of the brain, or one side of the brain, is abnormally larger than the other. As a consequence of this imbalance, the unusual and enlarged brain tissue causes frequent seizures, usually followed with mental retardation. Hemimegalencephaly may occur as an isolated finding in an infant or it may be associated with other syndromes.

    Surgery is often prescribed to control the seizures. If the affected side is surgically removed (hemispherectomy), the remaining healthy side of the brain may gradually take over the functions whose control has been lost. The ability for one side of the brain to take over the function of the other is known as plasticity.
