Epilepsy surgery may be an option in children with focal seizures that continue despite failed medical treatment. Children should be referred for assessment if they meet one or several of the following:

  • All children <24months of age with suspected focal seizure onset with or without identifiable lesion on brain MRI including those with catastrophic onset epilepsy and developmental regression. (All children <24 months should have a paediatric neurologist involved in their care).
  •  All children of any age with seizures and unilateral lesions on MRI, i.e. cortical malformation, developmental tumour, acquired brain injury, hippocampal sclerosis.
  • Certain aetiologies and constellations require special consideration including Sturge Weber syndrome, unilateral structural brain lesions (i.e. cortical dysplasia or developmental tumours) associated with developmental regression +/- continued seizures, Rasmussen syndrome, hypothalamic hamartomata
  • All children of any age with medication resistant seizures suggestive of focal onset and no identifiable lesion on MRI, that have failed treatment with ≥ 2 AEDs
  • Children of any age with Tuberous Sclerosis with seizures resistant to two AEDs should be evaluated to see if seizures arise from resectable tubers located in one hemisphere.
  • Children who have ‘drop attacks’ as part of a more complex epilepsy, with or without structural brain abnormalities, may also be suitable for a corpus callosotomy.
