A wire that travels under the skin connects the device to the electrode. The amount of stimulation delivered by the electrode is controlled by a pacemaker-like device placed under the skin in the chest. But surgery may allow you to take a lower dose.ĭeep brain stimulation involves implanting an electrode deep within the brain. If you have surgery for frontal lobe seizures, it's likely you'll need anti-seizure medicine after the surgery. Functional MRI (fMRI), in particular, is used to map the language area of the brain. This helps to rule out surgery on certain areas of the brain. Then electrical stimulation is used to determine whether that area has an important function. Brain mapping involves implanting electrodes into an area of the brain. These include single-photon emission computerized tomography (SPECT) and subtraction ictal SPECT coregistered to MRI (SISCOM).Īnother imaging technique, known as brain mapping, is commonly used before epilepsy surgery. Imaging techniques can help identify the area generating seizures. Before surgery, the goal is to find the areas of the brain where seizures occur. If your seizures can't be controlled with medicines, surgery might be an option. In vagus nerve stimulation, an implanted pulse generator and lead wire stimulate the vagus nerve, which leads to stabilization of irregular electrical activity in the brain. A video EEG allows health care professionals to match what physically occurs during a seizure with what appears on the EEG. Both a video camera and an EEG monitor run all night. This test is usually performed during an overnight stay at a sleep clinic. Video EEG is recommended for some people with seizures. However, EEG results might not identify frontal lobe epilepsy. EEGs often help diagnose some types of epilepsy. This is done by attaching small metal discs called electrodes to the scalp. An EEG monitors the electrical activity in the brain. ![]()
