Trevor's VEEG reports

VEEG September 12, 2005

Background Activity/interictal abnormalities:

The awake background shows symmetrical 5-6 Hz disorganized activity,

posteriorly, intermixed with 6-8 Hz high amplitude waves. During sleep,

symmetrical sleep spindles and vertex sharp activities were seen. Rare

generalized spike and wave activity was recorded during the study. Also,

infrequent spike activity was seen over the posterior quadrants with a maximun

at 01.

Clinical events/electrographic correlates:

The ptient had 2 type of events recorded during the study. The most common type

of events was characterized by behavior arrest(what is this???) and oro-lingual

masticatory movements. Electrographicaly, there was sharp and spike wave

activity coming from the right temporal area at T4, spreading to the right

hemisphere and lasting approximately 4 minutes.

The second type of seizures were characterized only by staring lasting 1 min.

Electrographcally, there ws ill definied focal onset on the left anterior

quadrant with a max over F3.

The patient has a single third type of seizure characterized by right arm

dystonic posturing, head deviation to the right, oro-lingual movements and

generalized jerking. Electrographically, there was sharp and wave activity

coming from the left anterior area with a max at P3 and secondary spread to the

left hemisphere, lasting approx. 8 minutes.

Impression:

This is an abnormal VEEG study due to slow, poorly organized background.

Interictal spike activity was seen over the left posterior quadrant. Multiple

seizures were captured during the study showing an onset over either the right

temporal and left anterior quadrant. There is no predominance of epileptogenic

dysfunction over either side.

EEG

Description:

At the onset of recording the patient is described as awake. A well developed,

well sustained background rhythm is not present. A remarkable feature of this

tracing comprises sharp waves, each with after following slow wave, emanating

from the left parietaloccipital region. No ictal discharges are seen. A number

of spells occur of various description, including mouth twitching and staring;

however, none of these display an EEG ictial correlate.

Well-developed, well-sustained stage 2 sleep is not recorded.

Impression:

This is an abnormal EEG because of the presence of interictal epileptiform

activity emanating from the left parietal occipital region, and the absense of a

well developed well sustained background rhythm. Taken together these findings

are consistent with an increased tendency to seizures, likely of partial origin

(based on this EEG).

The findings are also consistent with a diffuse encephalopathic process,

although they are not specific with regard to etiology. No ictal discharges

were identified. Clinical correlation is advised.

7/14/03 Nemour's Children's Clinic ville, Flordia

EEG

Description:

The patient was awake througout the majority of this recording and at times

agitated with muscle and motion artifact frequent. Noted in a prominent manner

throughout the recording were left occipital sharp waves. These were high in

amlitude and would occur in a frequent manner during wakefulness. A dominant

background rhythm with eye closure was not well established and would consist of

a predominant theta pattern with a fair anterior to posterior gradient.

Stobe light stimulation had no significant affect upon the background pattern.

Impression:

This EEG is abnormal related predominantly to the presence of left occiptial

sharp waves and spike wave discharges. This is indicative of a tendency towards

a focal seizure disorder. The patient's awake background rhythms appeared

disorganized for age, but htis was difficult to assess due to the patient's

overall lack of cooperation. Carefull clinical correlation is advised.

7/13/2001 Medical University of SC

VEEG

Description: During the waking state, predomiant posterior resting frequency,

as demonstrated at 1:25,

a rhythmic, symmetric, bioccipital 9.0-11.0 Hz 40-80(V rhythm with reactivity to

eye opening and clsure demonstrated. Multifocal sharp transients are

demonstrated throughout the tracing in the left posterior parietal(P3) and right

cetnral parasagittal lead C4. Intermittent generalized, sharp and slow wave

occur that are posteriorly predominant, left greater than right.

The remaining background activites consisted of mixed frequency, 4-7 Hz,

50-200(V rhythms, in the central regions bilaterally. Drowsiness was

demonstrated by slow rolling eye movements followed by loss of bacground waking

activities.

Photic stimulation was performed at frequencies between 1 and 21 Hz

demonstrating symmetric bioccipital driving responses at a wide range of

frequencies. No overt ECG abnormalities were noted. Minor muscle, motion and

eye movement artifacts were occasionally noted.

Interpretaton:

Abnormal EEg due to transient posterior spike and wave activity og greater

amplitude on the left.

This EEG is indicative of a lowered seizure threshold with a propensity toward

partial and /or secondary generalized seizures.
