What is the purpose of EEG for a temporal lobe seizure?

Locate focus. Eeg- electroencephalography is utilized in temporal lobe seizures and other seizure disorders to localize the focus of the seizure. Sometimes when the focus is found, there may be a surgical solution for the seizure and the focus can be removed.

Following a severe tbi, I was having possible seizures. Sharp waves were found on my left temporal lobe on eeg. Does that mean I have epilepsy?

Correlations. Brain trauma can eventuate with post-traumatic epilepsy, and the question of possible seizure activity is supported by a focal eeg abnormality c/w seizures. Your physician can pull all of this together, and i cannot confirm whether your possible szs. Are indeed in need of anti-epileptic drugs, but sounds like this may be your safest scenario. Best of luck. Read more...

I understand that frontal lobe seizures do not show on EEG due to skull thickness and those deep in the brain are too far away. Is this correct?

Yes. This may be true. Some frontal lobe seizures may be diagnosed by video alone (when typical), even when the eeg does not show typical changes consistent with seizure. This is true with a deep frontal focus, or when the seizures are so violent that the eeg may not be interpreted. Other frontal lobe seizures may be visible on surface eeg. Read more...
Sometimes true. Sometimes, frontal lobe seizures show on surface (regular eeg). However, at other times, the focus may be too far away (e.g. In the inner part of the frontal lobe). In such cases, your neurologist may consider a surgical procedure in which electrodes are placed inside the skull closer to the surface of the brain for recording (they are called subdural electrodes).

It is my understanding that frontal lobe seizures do not show on EEG due to skull thickness, and those deep in the brain too far away is this correct?

Yes and no. Most abnormal discharges can be measured through the skull if done carefully. In some cases eeg is recorded directly off the surface of the brain with electrode grids, or from deep electrodes placed into specific regions of the deep brain. A good eeg tech and neurologist should be able to obtain the best quality recording to help to answer the question of abnormal activity. Read more...
Very likely. Since eeg is recorded on the scalp and frontal lobe seizures may be deep, we may need several eeg tracings before we record anything abnormal. Read more...

What happens to the brain during a temporal lobe seizure?

Electric storm. The brain is controlled by electrical impulses. These are usually well regulated and are very nicely controlled by brain circuits. When these impulses get out of control, then the brain reacts by producing dramatic behavioral events that are seen as seizures. If the region of irritation is from the temporal lobe, then the behavior may be very complex and difficult to manage. Read more...

What can be done for temporal lobe seizures?

It depends. Temporal lobe epilepsy is an old term for a partial seizure that seems to come from a temporal lobe region of the brain. It can be simple, complex, or can secondarily generalize. Initially a good quality eeg and MRI will help to localize and characterize the process. Initial trial of medication is appropriate, and consideration of epilepsy surgery is appropriate. Some cases are very difficult. Read more...

Is the absence seizures coming from the temporal lobe?

Complex partial szs. These previously were termed "temporal lobe epilepsy", and the temporal lobe is involved, especially in case of congenital or acquired, "mesial temporal sclerosis". So, in part, your seizures emanate there, and this could be a site of surgical intervention in some cases. We also are aware of more widespread provocation over the circuitry called the limbic area, so it may not be so anatomic. Read more...

Can pristiq (desvenlafaxine) cause temporal lobe seizures?

Not reported. Exceptionally high dose Pristiq (desvenlafaxine) could theoretically induce a generalized seizure but the routine daily dose would be highly unlikely to cause this, and there is no documented report of any experience of "temporal lobe seizures" related to pristiq (desvenlafaxine). Focal seizures of this sort are not caused by antidepressant medications. Read more...
Pristiq (desvenlafaxine) There were some cases of pre-marketing seizures in clinical studies. Some people have developed seizures when discontinuing pristiq (desvenlafaxine). However, i haven't read any literature reporting temporal lobe seizures. Read more...

I've had fasiculations for 2 years, worsened by bright florescent lighting. I have a DVA in temporal lobe. Am I actually having simple partial seizures?

Electroencephalogram. The best way to evaluate if you are having simple partial seizures is to consult a neurologist and have an EEG. It is essential that the EEG be done while you are having the twitching. If no twitching occurs during the routine EEG, then arrange for a prolonged study in the lab or an ambulatory EEG, which can record over a 24 hour period. Read more...

I believe I might have Temporal Lobe Seizures.?

See neurologist. See a neurologist and have a sleep deprived EEG. 50% of patients with epilepsy have a normal EEG the first time it is done. A neurologist taking a thorough history and doing an exam may make the diagnosis even if the EEG is normal. Read more...
Advice. If you have episodes of altered consciousness, this needs to be fully explored and diagnosed. You will need a neurologist to work with. Schedule an appointment. In meantime, do not drive, operate power equipment, do activities at heights. Read more...
