Your scalp will not be shaved, but the area under the electrodes will be cleaned to remove any excess oils from your scalp. Secondly, you may fall asleep during the EEG and this may reveal new information that would otherwise have been unseen. Firstly the tiredness may result in brain waves on the EEG which are not usually seen. You may have already had a standard waking EEG. These waves may or may not show evidence of seizure activity. The EEG generally records brain waves between seizures, called interictal brain waves. The likelihood of recording a seizure during a routine EEG is small. If you have a seizure disorder, you are twice as likely to have migraine headaches. In rare cases, the brain wave changes seen on the EEG show that a headache can actually be the only symptom of a seizure. Headaches may occur before seizures and are common after tonic-clonic seizures. Is it normal to have a headache after an EEG? When you are tired, there is more chance that there will be unusual electrical activity in your brain. Or they may ask you to wake up much earlier than you usually do. Why do you have to stay awake before an EEG?īefore you have a sleep-deprived EEG test, your doctor may ask you not to go to sleep at all the night before. Epileptiform abnormalities on electroencephalography (EEG) are related to seizure disorders and are a factor in determining risk of recurrence after a single unprovoked seizure. The topologic usefulness of EEG is limited, although it may be improved with computerization.Ĭlinical guidelines recommend that an EEG be obtained after a single unprovoked seizure in children and adults.

In general, MRI is good at telling us where the lesion is, whereas EEG is good at separating normal and abnormal primarily cortical function. Unless you are actively having seizures or are restricted by your doctor, you may drive home. You may have to use additional acetone at home to completely remove the glue. What Happens After an EEG? When the EEG is done, the electrodes are removed and the glue that held them in place is washed away with acetone. Hair products can make it harder for the sticky patches that hold the electrodes to adhere to your scalp. Wash your hair the night before or the day of the test, but don’t use conditioners, hair creams, sprays or styling gels.
