This was tested in people. That is the most reliable kind of research we share.
People were tested and watched, but no treatment was tried here.
The short version
Where a brain tumor sits, and its gene changes, may both affect how a person thinks and feels.
What was studied. Researchers tested 101 people who were newly found to have a glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary. They also tested 52 healthy people. Everyone took thinking and mood tests before surgery.
What they found. People with deep tumors and people with tumors near the surface scored about the same overall. But inside each group, gene changes mattered. In deep tumors, an IDH gene change: A small change in a tumor's IDH gene. It is the first thing your team looks at when naming an adult glioma, and it can affect which treatments are offered. Your pathology report says whether your tumor has it. See the glossary went with different mood and attention scores, and in front-of-brain tumors other gene changes went with empathy or short-term memory.
What this means, and what it doesn't
What it could mean: Your tumor's genes and its spot in the brain may both play a part in how you think and feel. Doctors may want to look at both when they check you before surgery.
What it doesn't mean: This does not mean a new treatment. It is not a cure, and it is not close to one. This was one study that measured people before surgery. No drug or therapy was tested. It cannot tell you what will happen to one person. It does not change the care you get today.
