- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This was a look back at brain scans in people, not a test of a treatment.
The short version
Brain scans taken before and after surgery may show who is more likely to have seizures later.
What was studied. Doctors looked back at 109 people who had a glioma: A tumor that starts in the glial cells. Those are the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4. The grade says how the tumor is expected to act. See the glossary in the front of the brain. Each one had brain scans before surgery and again 1 week after.
What they found. People who had seizures after surgery had weaker links between two brain networks. These networks help a person pay attention and focus. Stronger links between them, and stronger links from a deeper brain area, went with fewer seizures.
What this means, and what it doesn't
What it could mean: Scan patterns might one day help doctors see who needs closer watching for seizures. That could help them plan seizure medicine after surgery.
What it doesn't mean: This does not mean there is a new treatment. It was a look back at old scans, not a trial of any drug or surgery. No one has tested these scan patterns to guide real care yet. It is not a cure, and it cannot tell you what will happen to you.
