Brain tumors can cause seizures, but not all tumors have a high chance of doing so. Seizures can also be caused by other conditions. Different types of brain tumors have different rates of seizures, with ganglioma tumors having the highest rate. Seizures can be controlled with medication. Symptoms of brain tumors and seizures include headaches, personality changes, and memory loss.
Brain tumors and seizures are linked because individuals with certain types of tumors often experience seizures. These seizures are the result of complications created by the tumor, but not all brain tumors have a high chance of causing seizures. Some cause a higher rate of seizures than others, and there are many different causes of seizures other than brain tumors.
Although they are sometimes related, brain tumors and seizures are not always related. Seizures can be caused by a number of conditions, such as brain injury, infection, or complications from other medical conditions, such as diabetes or liver failure. Symptoms of an attack often include a change in consciousness, such as memory loss or complete unconsciousness, changes in vision, and uncontrollable muscle movements.
There are many different types of brain tumors that can affect an individual, and not all seizures and brain tumors are linked in the same way. A brain tumor is an abnormal growth of cells that develops in the brain. Ganglioma tumors have the highest rate of seizures – around 90%. More than half of patients with low- and high-grade glioma experience a seizure, while less than half of those individuals with glioblastoma and meningioma experience seizures.
Several factors can cause a brain tumor to trigger seizures. The tumor can disrupt the flow of electricity in the brain, causing a seizure. Brain tumors and seizures are also linked to the swelling and pressure a tumor causes on the brain, which is a common trigger for seizures. Seizures are often controlled with steroids that control brain swelling, as well as with antiepileptic drugs.
A number of different seizure classifications can be applied to brain tumors and seizures. Focal seizures involve only one part of the brain and can be simple or complex. Simple seizures do not lead to memory loss, but complex seizures do. In a focal seizure, only one part or side of the body may be affected. Unlike focal seizures, generalized seizures affect the entire brain and body.
Various symptoms are associated with brain tumors and seizures. Headaches are also a common effect of brain tumors and can differ from ordinary headaches in length, severity, and lack of response to typical headache medications. Personality changes may occur, along with short-term memory loss. Depending on the location of the tumor, more localized symptoms may occur. For example, if the tumor is located near the speech center of the brain, speech may be lost or be negatively affected.
