What we use an EEG for

An electroencephalogram (EEG) is a test that detects electrical activity in the brain using small metal discs (electrodes) attached to the head. EEG results show changes in brain activity that may be useful in diagnosing brain conditions especially epilepsy and other seizure disorders

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

During the test, small sensors are attached to the scalp to pick up the electrical signals produced when brain cells send messages to each other. These signals are recorded by a machine and are looked at by a doctor later to see if they're unusual.
