Over the past decade, treatment options have increased for frontal lobe seizures. There are newer types of anti-seizure medications as well as a variety of surgical procedures that may help if medications don't work.
All anti-seizure drugs seem to work equally well at controlling frontal lobe seizures, but not everyone becomes seizure-free on medication. Your doctor may try different types of anti-seizure drugs or have you take a combination of drugs to control your seizures. Researchers are continuing to look for new and more-effective medications.
If your seizures can't be controlled adequately with medications, your doctor may recommend surgery. Surgery involves pinpointing the areas of the brain where seizures occur. Two newer imaging techniques — single-photon emission computerized tomography (SPECT) and subtraction ictal SPECT coregistered to MRI (SISCOM) — are more accurate at identifying the area, but aren't yet widely available.
Another imaging technique, known as brain mapping, is commonly used before epilepsy surgery. Brain mapping involves implanting electrodes directly into an area of the brain and using electrical stimulation to determine whether that area has an important function, which would rule out surgery on that area. In addition, functional MRI (fMRI) is used to map the language area of the brain.
In general, surgery for seizures that aren't well controlled by medication may be quite successful. Surgery for frontal lobe seizures may be less successful than for other types of seizures, but still may provide benefit.
Surgery for epilepsy may involve:
- Removing the focal point. If your seizures always begin in one specific spot in your brain, removing that small portion of brain tissue may reduce or eliminate your seizures.
- Isolating the focal point. If the portion of the brain that's causing seizures is too vital to remove, surgeons may make a series of cuts to help isolate that section of the brain. This prevents seizures from moving into other parts of the brain.
- Stimulating the vagus nerve. Another surgical option is to implant a device — similar to a cardiac pacemaker — to stimulate your vagus nerve. This procedure usually reduces the number of seizures people experience.
- Responding to a seizure. A responsive neurostimulator (RNS) is a newer type of implanted device. It is activated only when you begin to have a seizure, and it stops the seizure from occurring.
