EEG Results & Tonic/Clonic Seizure

[GeorgiaC]

When my son was 5 days old he had viral meningitis. No problems until he was 15 when he had a grand mal seizure after staring at the sun. No problems until Jan 1, 2007 he was diagnosed with Type 1 diabetes and was told he had probably had it for awhile. He was hospitalized with ketoacidosis for 6 days. He is 19yrs old now. He is insulin dependant. In March he had a grand mal seizure at school outside after basketball practice. We assumed his blood sugar was low or it was the light. The neurologist had to reschedule his appointment twice. On June 30th he had another g/m seizure and then another on July 5th. Both of them were inside at his work when his blood sugar was normal. They were both actually video taped due to his place of employments security cameras. On July 6th we had tests ran. His blood work came back normal. His MRI states that although there is quite a bit of motion there is not evidence of temporal lobe lesions, atrophy, enhancing lesions, mass effect, arteriovenous malformations, diffusion defects or other abnormalities. This is using a 1.5 magnet MRI machine.
First, I would like to know what "quite a bit of brain motion" means.
The EEG states during the outset of the study the patient has a high amplitude background. His posterior dominent frequency is approx. 10hertz. During study there is a pseudo-quasi rhythmic, approximately 6 to 7hertz sharp activity seen bi-hemispherically. At times there is some further slowing into the delta beta range in the frontal head regions. During the study the photo stimulation and hyperventilation is not activating. There is some drowsiness seen with stage 1 and 2 sleep study. There is some muscle and movement artifact but it is otherwise an acceptable study.
Impression: This is an abnormal EEG. Although the activity on the study is not clearly epileptogenic in nature, it is clearly a non-normal appearing study and there are occasional generalized slowing in the quasi rhythmicity of the waveforms and larger amplitudes are certainly concerning for irritability. At the present time I can not identify a focal area of abnormality.
His neurologist is the one who dictated this report. Can you please tell me what all of that means in normal words. We can't get in for another 6 weeks.
Finally, would it be helpful in diagnosing my son if we could get a copy of the video of him having the seizures?

Thank you.
