Seizures Seizures Seizures are common symptoms of a brain tumor. For some people, a seizure may be the first clue that something unusual is happening in their brain. Seizures might be caused by a brain tumor or the surgery to remove it.
Seizures can also be totally unrelated to a brain tumor.
For example, an injury to the head, a stroke, alcohol or drug withdrawal and fever can all cause seizures. Or, the cause may be unknown. Seizures are particularly common with slow growing gliomas, meningiomas located in the convexity of the brain, and with metastatic brain tumors. Sometimes, seizures help alert the doctor to the presence of a tumor. Most seizures can be controlled with medications called antiepileptics.
