- Tested in people
This was tested in people. That is the most reliable kind of research we share.
Doctors looked back at patients who already had surgery, so this is not a new treatment.
The short version
Children who had most of their brain tumor taken out were more likely to be free of seizures.
What was studied. Doctors looked back at 47 children and young adults with a brain tumor called a ganglioglioma. All of them had seizures. The average age at surgery was 13.1 years. Doctors measured how much of each tumor was removed.
What they found. Surgeons took out all of the tumor in 48.9% of cases. At 12 months after surgery, 76.6% of patients had no seizures. Taking out at least 84% of the tumor was linked to being free of seizures.
What this means, and what it doesn't
What it could mean: How much tumor is removed may matter, not just whether every bit is gone. If taking out the whole tumor is not safe, getting most of it out may still help with seizures. This is a fair thing to ask your surgeon about.
What it doesn't mean: This does not mean surgery stops seizures for everyone. Doctors looked back at records from one group of 47 patients at one hospital. That kind of study can show a link, but it cannot prove cause. It is not a new treatment and it is not a cure. Some patients had their seizures get worse later when the tumor came back. What is right for you depends on where your tumor sits and your own health.
