Parents deserve accurate, research-based information when deciding whether their child should have epilepsy surgery – especially large procedures like hemispherectomy, single or multiple lobectomies, large resections, and similar surgeries which disconnect large parts of the brain.
Just as it is important to understand the consequences of uncontrolled seizures, having a roadmap that guides parents through the potential impact of surgery on various functions of the body is critical — and not just for parents, but for doctors and therapists who treat these children after surgery and into adulthood.
That’s why on July 18, 2019, we held a meeting to understand what the scientific research says so far about the long-term benefits and challenges of large pediatric epilepsy surgeries in the areas of motor, orthopedic, sensory, behavioral, medical, and cognitive challenges across the lifespan.
Here’s how we defined large pediatric epilepsy surgeries for this meeting:
The meeting also helped us identify research gaps in these areas, and will help to answer questions parents often have:
- Expectations: Given my child’s epilepsy, cause of epilepsy, and our preferences, what should we expect to happen to our child after epilepsy surgery?
- Choices: Given my child’s epilepsy surgery options, what are the benefits and harms of those options?
Although brain surgery to stop seizures is being used more every year, there isn’t much scientific research to help parents and doctors understand the long-term benefits and challenges of surgery.
This leads to anxiety, uncertainty, and a lack of evidence-based guidance for parents and clinicians who want to help children achieve their full potential after surgery.
For the first time, parents, patients, doctors, and researchers discussed what to expect after surgery. Parents identified the topics for discussion, helped create the agenda, and were invited to share their personal experiences to an audience of researchers and doctors.
This has never been done before.
Here’s What Happened
Listening to the patient voice
The meeting began with opening remarks and a brief presentation from Monika Jones, Project Lead. An overview of preliminary data results from the patient-powered Global Pediatric Epilepsy Surgery Registry, common themes discussed by The Brain Recovery Project’s community advisory council, as well as patient-reported trends and themes from various social media groups were presented.
The opening keynote address was delivered by neuroscientist Bryan Kolb, PhD, who is the Board of Governors’ Research Chair in Neuroscience at the University of Lethbridge. Dr. Kolb’s research focuses on the organization and functions of the cerebral cortex. Dr. Kolb has contributed extensively to the literature of neuroplasticity during development and in response to experience, drugs, hormones and injury, including how these changes influence behavior. His 1980 textbook Fundamentals of Neuropsychology, co-authored with colleague Ian Whishaw, helped define the field of neuropsychology and as of 2015 is in its seventh edition.
On The Frontlines: The Clinicians’ Perspective
Following the opening keynote, a panel featuring six directors of level 4 pediatric epilepsy programs addressed questions about information available to them to help counsel and advise parents of functional outcomes and the insight they have into the long-term functional impacts of the surgery for their patients.
The clinicians expressed that some data exists around surgery’s effectiveness to control seizures, but minimal research is available around the functional impacts of surgery, or the potential interventions post-surgery that could help a child reach an optimal outcome. Data that does exist is limited to single centers.

For the rest of the day, the group learned about and discussed the existing research and gaps related to each of the six functional areas:
- motor and orthopedic
- behavior and sensory
- speech and language.
For each area, the patient perspective was shared first. Then, researchers in each area made their presentations.
The researchers had a tough job – summarize what the research says in about 15 minutes and using “plain English” so that non-medical persons could understand their presentations.
After each area was discussed, the stakeholders would break out into small groups where they discussed the presentations and prioritized future research.
While the presenters talked, a professional graphic recorder, Johnine Byrne of See Your Words, captured the key points in her drawings.

The final mind map showed the group’s decision on future research priorities:
What We Decided
The group agreed that there are huge research gaps in all areas discussed. In some areas there wasn’t even a basic understanding of how large pediatric epilepsy surgeries may impact that functional area.
For example, we don’t fully understand the potential long-term impacts on a child’s endocrine system — research there is totally absent.
As a result, we decided that the most impactful first step for the families we serve would be to establish and publish a “Best Practices” framework which would provide parents and clinicians with a roadmap based on what we know so far.
Another important outcome of the meeting was that the doctors gained a better understanding of how the surgeries can impact a child as they grow up. It was powerful for them to hear firsthand from parents and adults who had surgery in childhood about the long-term challenges they face.
One surgeon had this to share:
“The main upshot of this conference for me was that there is a lot of focus on the acute care of children with catastrophic hemispheric epilepsy, but the long-term comorbidities and drivers of quality of life have received far less attention. Surgeons and neurologists need to play a long-term role in the care of these patients and quarterback the management of long-term surgical and medical comorbidities. This meeting was extremely powerful for me. Actually, we immediately changed some of our practices at our children’s hospital as a result of this meeting – including preoperative physiatry consults, which were not already part of our program. Also, we’ve begun a retrospective cohort study of our own hemispherotomy patients to investigate their long-term comorbidities.”
Another key outcome was the formation of a research consortium. After the meeting, several clinicians and researchers committed to driving the “Best Practices” framework forward by sharing it at professional meetings and scientific conferences.
We are working on next steps with this consortium, which includes drafting, publishing, and distributing the best practices guide for each clinical area after surgery, preparing slides and presentations for them to share at their scientific conferences, and initiating new research to start to fill in those research gaps.
Our deepest gratitude to everyone who made this conference possible
Thank you for inviting me to be part of this. I am not sure if it could have been any better 🙂 Kudos to the team.
Really great meeting. I learned a ton and humbled (and inspired) by my experience.
Great meeting – it was so helpful to have all interested parties around the table. I also found it very helpful to learn about outcomes that fall outside my area of expertise.
This was an amazing meeting and I hope I can continue to be involved in the future. Strength in numbers – it is going to take a network/team.
Terrific meeting as it exposed the absence of information we have regarding the long term outcomes and interventions following big resective surgery in children.
Very informative and useful meeting to have all types of stakeholders present.
This meeting was truly exceptional! The structure was excellent for engaging all participants and the selection of participants was great. This is my new benchmark for excellence in family-clinician collaboration.
It was an excellent meeting and the illustrations were very helpful to see the priorities. The conference was well planned and executed with much collaboration among key stakeholders, researchers and patients.
This convening was an incredible opportunity and I’m newly collaborating with colleagues I met there on hemispherectomy research as a direct consequence.
This is how our community is getting stronger. I wish we could “advertise” to other major surgery centers to get more neurosurgeons and neurologists on board with the holistic approach that, I hope, will come out of this work.
Congratulations on such a successful event in bringing different stakeholders together. Looking forward to the great work developed as a group and the collaborations engendered by this meeting.
Great job. Your team should be so proud. I think outlining what best care looks like for your pt population is a very solid next step.
Great meeting – well organized and very informative. Looking forward to next steps.
This was a great event and I feel blessed to be a tiny part of it. Looking forward to helping the BRP move forward with this campaign.
