Making Sense Out of an EEG | Epilepsy Foundation
This test tries to record the EEG when the person is having symptoms thought to be seizures. Then the electrical activity of the brain at the time of the symptoms can be looked at in detail. This is the best way to tell if an episode or event is an epilepsy seizure. What does it mean when an EEG shows spikes, sharp, or slow waves?
What if the EEG is Normal? | Epilepsy Foundation
The EEG generally records brain waves between seizures, called interictal brain waves. These waves may or may not show evidence of seizure activity. The neurologist looks for spikes or sharp waves ("epilepsy waves") to confirm the diagnosis, but the absence of these abnormal brain waves does not mean you didn't have a seizure in the past.
Electroencephalography (EEG) for Epilepsy | Brain Patterns
Some abnormal patterns may occur with a number of different conditions, not just seizures. For example, certain types of waves may be seen after head trauma, stroke, brain tumor, or seizures. A common example of this type is called "slowing," in which the rhythm of the brain waves is slower than would be expected for the patient's age and level ...
How to Read an EEG - Epilepsy Foundation
The EEG records brain waves using equipment called amplifiers and by looking at the information from the electrodes in different combinations. These combinations of electrodes are called 'montages'. In bipolar montages, consecutive pairs of electrodes are linked by connecting the electrode input 2 of one channel to input 1 of the subsequent ...
veeg and brain waves - Epilepsy Foundation
I have had 3 eeg's. Two of them were mildly abnormal and the last one was abnormal. Now my Dr. wants a veeg. My question is what will a veeg show that the eeg's did not. Are the abnormal brain waves that showed up on my last eeg different from seizure brain waves? From what I understand a successful veeg is determind whether or not you have a seizure. What is the difference between abnormal ...
Where is EEG performed? | Epilepsy Foundation
Subtle changes in brain waves may be interpreted as abnormal when the actual change is this kind of normal variant. Interpreting EEGs also involves some subjectivity and judgment. (This is why the machine doesn't just spit out the interpretation along with the strip!) What one interpreter reads as sharp waves may be read as spikes by another.
Diagnosis Through an Ambulatory EEG | Epilepsy Foundation
The brain’s electrical activity fluctuates from second to second, but routine EEGs provide only a 20- to 40-minute sample of this activity. If epilepsy waves occur in your brain only once every 3 or 4 hours, or if they only happen at certain times of day, a regular EEG might not record them.

Continuous Video EEG Monitoring – studies the brain waves over time with a patient staying in a special unit for at least 24 hours. Antiepileptic medication is stopped for the duration of this test, since the objective is for seizures to occur so the abnormal brain waves they produce can ...
