During this painless test, small sensors are attached to the scalp to pick up the electrical signals produced by the brain. These signals are recorded by a machine and are looked at by a doctor. The EEG procedure is usually carried out by a highly trained specialist, called a clinical neurophysiologist, during a short visit to hospital. When an EEG is used An EEG can be used to help diagnose and monitor a number of conditions affecting the brain. It may help identify the cause of certain symptoms – such as seizures (fits) or memory problems – or find out more about a condition you've already been diagnosed with. The main use of an EEG is to detect and investigate epilepsy, a condition that causes repeated seizures. An EEG will help your doctor identify the type of epilepsy you have, what may be triggering your seizures and how best to treat you. Less often, an EEG may be used to investigate other problems, such as: dementia head injury and concussion brain tumours encephalitis (brain inflammation) sleep disorders, such as sleep apnoea. Preparing for an EEG Your appointment letter will mention anything you need to do to prepare for the test. Unless told otherwise, you can usually eat and drink beforehand and continue to take all your normal medication. To help the sensors stick to your scalp more easily, you should make sure your hair is clean and dry before arriving for your appointment, and avoid using products such as hair gel and wax. You might want to bring a hairbrush or comb with you, as your hair may be a bit messy when the test is finished. Some people bring a hat to cover their hair until they can wash it at home afterwards. How an EEG is carried out There are several different ways an EEG recording can be taken. The clinical neurophysiologist will explain the procedure to you and can answer any questions you have. You'll also be asked whether you consent to treatment for the various parts of the test to be carried out. This may include video consent for some EEGs. Before the test starts, your scalp will be cleaned and about 20 small sensors called electrodes will be attached using a special glue or paste. These are connected by wires to an EEG recording machine.
