Deep brain stimulation to control epileptic seizures

This procedure is carried out under local anaesthetic. The neurosurgeon will first implant small electrodes in the brain. The precise position of the electrodes will vary depending on the symptoms and which areas of the brain need targeting.

You will remain awake during the surgery so that the team can monitor your brain function as they place the electrodes. The electrodes are then connected to a tiny pulse generator which is implanted in the chest or abdomen area.

The pulse generator delivers electrical stimulation to the target area of the brain. This alters some of the neural pathways which cause epileptic seizures.

Your consultant will explain the procedure to you and answer any questions you may have. Like all procedures, there may be some risks and side effects involved. Your consultant will explain these to you.

When you have recovered from your surgery, the neurostimulator will be activated by your consultant. They will show you how to use the device and tell you when you may need to switch it off.

DBS will lessen your symptoms, but you will still need to take your epilepsy medication to help prevent seizures. Your consultant will monitor your progress over the following months.
