Glioma symptoms depend entirely on where in the brain it grows. Do not dismiss a new neurological symptom that does not resolve. If you notice any of the following for more than two weeks—especially if it is new and progressive—seek expert evaluation immediately:
Symptom | What to Watch For |
Progressive headache | Worse in the morning, with nausea, or aggravated by coughing/bending. |
Seizure | Any new-onset seizure in an adult warrants brain imaging. |
Focal weakness or numbness | One-sided arm/leg weakness, facial droop, or hand clumsiness. |
Speech or comprehension | Struggling to find words, slurred speech, or difficulty understanding others. |
Personality or cognitive change | Uncharacteristic irritability, apathy, memory lapses, or poor judgment—common in frontal lobe tumors. |
Visual field loss | Bumping into objects on one side, or tunnel vision. |
