Doctor insights on:
48 Hour Eeg
May not matter: These 'long' seizures are typicallly there to capture an event. So as you ask, what happens if you do not have an event? There still may be abnormal electrical activity detected that does not manifest a full seizures (interical activity), this is important to know as well. ...Read more
Right now I am undergoing a 48 hour ambulatory eeg test and I am a regular cannabis user, will this alter my results in any negative ways?
It depends: It depends on why you're having an EEG. You should ask the physician who ordered the EEG or the office where it will be performed regarding how sleep-deprived you should be. The general rule of thumb is that sleeping for less than your routine sleep duration may increase the chances of detecting abnormalities, if they exist. Ref: http://www. Cc.nih.

How many different conclusions or insights can be made from a 24 hour ambulatory EEG test results?
None: If it's normal.Get a more detailed answer ›
I am currently partaking in a 24 hour eeg brain testing. Is it possible that me masturbating can cause a change in the results?
No effect: No, this would not affect the results. ...Read more
My doctor sent me for an EEG today, awaiting results. However I have a massive headache now (two hours after eeg). Is this normal?
EEG: An eeg is a study of the brains electrical activity. This should not cause any headache. If they did photic stimulation during the eeg, it may be possible that it could have caused a migraine like headache, but the eeg study itself would not cause a headache. Please contact your doctor to let them know. ...Read more
My daughter just had a 72 hour EEG I saw a lot of XL spike and xlevent w/o seizure activity. What are XL spike and XL event? Did I miss a seizure?
Depends: Xl spike and xl events are computer generated markers on an eeg which may or may not represent epileptic spikes or seizures. Most of the time these are false detections, meaning that the computer thinks there is an abnormality, but there is none. The eeg specialist has to review the eeg recording and make his/her own judgment as to whether there are actual epileptic spikes or seizures. ...Read more
Can smoking Weed 8 hours before a EEG test affect the results? I had a seizure 3 months ago and have not been able to drive because of it. This EEG is
My 2 yr son suffered seizures 3 months ago, doc said the EEG was abnormal. Today again his EEG is abnormal. Is it safe to travel by air for 24 hours?
Febrile seizures?: The most common seizures at that age are those associated with illness with fever. Eeg at that age is very difficult to interpret. If he is not well and otherwise doing well, air travel should be no problems. Ask your doctor, but treatment with Lorazepam tablet 0.5mg just before the flight would be safe with another dose during flight if indicated. ...Read more
1 year old having a seizure? My daughter is 1 and has been having seizures for months, she's had a EEG done and results where normal, and for 3 weeks she didn't have one so I was happy, and just half an hour ago she had one I think. She was sitting j
Unfortunately,: Unfortunately, this episode is also consistent with a "staring spell" or absence seizure. With the frequency of the seizures that you describe your daughter will most likely need to be started on a mediation. An eeg is a very sensitive test but does not always show epileptiform activity in between seizures. I would probably start your daughter on an anti-seizure medication to help prevent seizure activity. ...Read more
Dizziness, vision blurriness, & confusion that lasts hours or days on/off x 3 yrs. Prednisone clears up sx. MD wants EEG. Worth it? Tired of useless tests
Yes: These symptoms sound like central (brain) disorder. The EEG may give important information. The fact that prednisone helped may indicate an inflammatory disorder. See a neurologist. The fact that the symptoms have been present for 3 years strongly indicates that you should have an MRI of the brain. All these symptoms for such a long time really needs a neurological diagnosis ASAP. ...Read more
What are neurologists looking for in a 72 hour eeg. He saw three white places in a CT scan. To me these spots looked like the skull. White.
Short lived events: An eeg is only able to capture events that occur while the leads are attached. Ambulatory eegs allow longer-term monitoring to capture these infrequent events more reliably. One typical application is spells that might be seizures- if the eeg during a typical spell does not show seizure activity, that argues strongly for another cause. ...Read more
Is it normal to have dizziness, nausea, vomiting, feeling faint, hours after, and during EEG? Should I be concerned? Didn't know it would make me sick
EEG lead glue: Some types of glue used in some EEG labs to make the electrodes stick to your scalp can have very irritating odors or chemicals. For some, it may just smell bad; for others, it may irritate the upper airways; and some others may get stomach and/or headache. It should pass within a few hours. Feel better! ...Read more
I am on Lamictal for Bi Polar Disorder and Topamax for migraines, I am scheduled for a 24 hour EEG, should I skip my meds in preparation for my test? I was told they could possibly cause my test results to be inaccurate. If so how many days before hand
Do NOT stop meds.: Where did you receive such INANE advice? If you suddenly stop your meds, both of your conditions could exacerbate. Talk to your doctor about how to properly manage your meds, with/ or without tests. ...Read more
Brain activity: Eeg is a test of physiological function, and records brain electical activity (like electrocardiogram for heart). It is used to check for seizure activity, to evaluate various headache issues, to check patients with memory loss, evaluated folks with brain infections, and also confirm brain death. ...Read more
Electrical recording: In the same way an ekg measures electrical activity from the heart, an EEG measures activity from the brain. Electrodes are placed on the scalp and the patient lies quietly while brainwaves are recorded. Sometimes, hyperventilation and/or flashing lights are used to evoke different responses. It is important to relax, as electrical activity from muscle can swamp the signals from the brain. ...Read more
VAGUELY ACCURATE: An EEG is a recording of brain electrical activity taken over the scalp, over about 45 minutes. This brief period may completely miss many paroxysmal events and provide a false negative/normal result. Work with direct electrodes implanted into brain have convincingly demonstrated far more pathology than external recordings. So, basically "hit or miss" issues, and better to clinically assess. ...Read more
