This was tested in people. That is the most reliable kind of research we share.
This was a look back at past patient scans, not a test of any treatment.
The short version
People with glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary who have seizures often live longer, and brain wiring may be part of the reason.
What was studied. Researchers looked back at records for 420 people with glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary. Each had a brain scan before surgery that shows how brain areas connect.
What they found. Of the 406 people who could be sorted, 217 (53%) had seizures caused by the tumor. Those people had stronger local connections in brain networks, on both sides of the brain. Better overall connection patterns on the side away from the tumor went with living longer. The wiring explained only a small part of the link between seizures and longer life.
What this means, and what it doesn't
What it could mean: This may help doctors understand why some people with glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary live longer. It does not change the care you get today.
What it doesn't mean: This does not mean seizures are good for you. No new treatment was tested here. It was a look back at past scans and records, so it cannot prove cause. It is a long way from everyday care, and it is not a promise of a cure.
