Infantile spasms are the most common catastrophic epilepsy in childhood. Children who have infantile spasms that are drug resistant should be referred to a qualified pediatric epilepsy surgeon at a level 4 Epilepsy Surgery facility as soon as possible.  There, the team will determine whether resection surgery (removing part, and in some cases disconnecting/removing up to half, of the brain) is recommended.

The criteria for resective surgery for infantile spasms are:

  1. the infantile spasms are drug-resistant;
  2. the child has stopped developing (developmental arrest) or has regressed;
  3. there is no evidence of diffuse brain damage on imaging studies;
  4. there is a “zone of cortical malformation” on MRI or PET scan;
  5. there is no evidence of metabolic or degenerative disease;
  6. there is no undue risk of “unacceptable deficits” after resective surgery.

 

Dr. Don Shields, a renowned expert in infantile spasms, discusses infantile spasms, cognitive prognosis, and hemispherectomy surgery to stop infantile spasms here:
