This is a digitally recorded electroencephalogram.
The international 10-20 electrode placement system is used for scalp electrode placement.
Eighteen channels of scalp EEG are recorded
One channel was used for EOG.
Another channel was used for for ECG.
The data are stored digitally and reviewed in reformatted montages for optimal display.
9 to 10 hertz alpha activity was seen.
Maximal over the posterior head region.
These activities are symmetric on both sides.
They attenuated with eye opening.
Small amount of beta activities are seen.
No focal slowing was seen.
No seizure like activity was observed during this recording.
Patient entered into periods of drowsiness and light sleep.
No abnormality was seen.
No well formed alpha activity was seen.
Mixed diffuse theta and delta activity was seen.
Frontal intermittent rhythm delta slowing was seen.
Triphasic wave was seen.
Increased beta activity was seen intermittently.
Bilateral periodic lateralized Epileptiform discharge (BiPLED) was seen.
Markedly suppressed EEG activity was observed.
MInimal EEG activity was observed throughtout the recording.
Intermittent focal slowing was seen.
Cotinuous polymorphic delta slowing was seen.
Periodic lateralized discharge was seen.
Mainly over the Left temporal area.
Mainly over the Right temporal area.
This is seen over the Left hemisphere.
This is seen over the Right hemisphere.
Thiis activity is seen over bilateral hemisphere.
Normal EEG. No focal slowing no seizure like activity was observed.
Correlation with clinical findings is needed.
This EEG is abnormal.
Diffuse slowing is seen, suggestive of a diffuse abnormality of the brain.
This finding is nonspecific, and can be seen in a diffuse or multifocal abnormality of the brain.
PLED's is seen, this is suggestive of a subacute structural abnormality of the brain, and patient may be prone to haveing a clinical seizure.
Epileptiform discharge was seen. This can represent a potential seizure focus.
Some focal slowing was seen, suggestive of a focal abnormality.
Clinical correlation is needed.
