An EEG is a routine investigation performed on all age groups of patients to help in the diagnosis of many disorders of the brain. An EEG records the electrical activity that your brain produces while sending and receiving messages to and from your body.
A sleep deprived EEG may be requested in some instances. It involves staying awake all the night before the test, preferably without the help of beverages containing caffeine. It is hoped that by staying awake, a patient goes to sleep during the test. This increases the yield of capturing any abnormal waveforms signifying underlying seizure predisposition. When sleep deprived, some types of seizures are more likely to occur.
The investigation will be carried out by a scientist who will explain every step of the procedure as they progress and will take about 30 minutes.
There may be some manoeuvres during the test e.g., observing flashing lights or taking deep breaths.
Occasionally, a patient may need prolonged monitoring, for example, for 3 days. There is no gap for this service.
