    A routine EEG recording lasts for about 20 to 40 minutes. During the test, you'll be asked to rest quietly. You will usually be asked to open or close your eyes from time to time. In most cases, you'll also be asked to breathe in and out deeply (called hyperventilation) for a few minutes. A flashing light may also be used to see if this affects you...

    A sleep EEG is carried out while you're asleep. It may be used if a routine EEG does not give enough information, or to test for sleep disorders. In some cases, you may be asked to stay awake the night before the test to help ensure you can sleep while it's carried out. This is called a sleep-deprived EEG.

    An ambulatory EEG is where brain activity is recorded throughout the day and night over a period of one or more days. The electrodes will be attached to a small portable EEG recorder that can be clipped onto your clothing. You can continue with most of your normal daily activities while the recording is being taken, although you'll need to avoid ge...

    Video telemetry, also called video EEG, is a special type of EEG where you're filmed while an EEG recording is taken. This can help provide more information about your brain activity. The test is usually carried out over a few days while staying in a purpose-built hospital suite. The EEG signals are transmitted wirelessly to a computer. The video i...

    This EEG is not common, but it may be used to check if surgery is possible for some people with more complex epilepsy. It involves surgery to place electrodes directly on the brain to find out exactly where the seizures are coming from.

    • Epilepsy. Epilepsy is a neurological seizure condition that occurs in one of several parts of the brain. The main symptom of epilepsy is recurrent seizures due to unusual electrical brain activity.
    • Sleep disorders. Sleep disorders include problems with the amount or quality of sleep a person has, often due to an underlying physical or emotional cause.
    • Traumatic brain injuries. Head injuries, or traumatic brain injuries (TBIs), occur when a strong force to the head causes damage to the brain, resulting in temporary or permanent impairment of cognitive, physical, and psychosocial functions.
    • Brain infection or inflammation. Brain inflammation, or encephalitis, primarily occurs after a viral infection. Other causes may involve the immune system mistakenly attacking brain tissue.

    What are the benefits of a sleep-deprived EEG ? Going without sleep mildly stresses the brain, and so recording the EEG after sleep deprivation may give added diagnostic information. Also, if you are able to fall asleep during the test, extra information may be gained from your brainwaves in sleep. What are the risks of sleep deprivation?
