- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This looked at people who had already been treated, and it did not test any treatment.
The short version
Years after surgery, people whose brain networks looked more like healthy patterns did better on thinking tests.
What was studied. Researchers studied 61 people who had been treated for an IDH mutated glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are graded 1 to 4 by how fast they tend to grow. See the glossary, a type of brain tumor. Everyone was 5 to 21 years past surgery. Each person had a brain scan while resting, took tests of thinking and memory, and answered questions about mental fatigue, anxiety, and depression.
What they found. People who did better on tests of planning, thinking speed, attention, and language had brain networks that looked more like healthy brain patterns. Different kinds of memory were tied to different networks. Memory for things people saw was linked to one network, and memory for words to another. People with more mental fatigue also did worse on those same thinking tests. Three groups stood out, and they differed in mood symptoms and in how their brain networks were organized.
What this means, and what it doesn't
What it could mean: Trouble with thinking and lasting fatigue after glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are graded 1 to 4 by how fast they tend to grow. See the glossary treatment may be tied to how brain networks are organized. Fatigue, mood, and thinking appear to be connected to each other. The authors suggest that rehab aimed at specific brain networks might help. That is an idea from this study, not something it tested.
What it doesn't mean: This is not a new treatment. It was a study that looked at people and measured them, not a trial of any therapy. Nothing here was shown to improve thinking or fatigue. The brain scans used were a research tool, not a scan your doctor can order to guide your care today. This is not a cure, and it does not promise one.
