Once your test is completed and equipment is returned, your neurologist will compare your brain waves to what is considered normal for your age.
Is there a 24-hour EEG test?
An Ambulatory EEG (Amb EEG) is a safe, painless test which will record the electrical activity produced by your brain. An Amb EEG uses a digital recording system to record brain activity for 24-72 hours while you go about your daily routine.
Does EEG show brain damage?
An EEG can determine changes in brain activity that might be useful in diagnosing brain disorders, especially epilepsy or another seizure disorder. An EEG might also be helpful for diagnosing or treating the following disorders: Brain tumor. Brain damage from head injury.
