What are causes of abnormal EEG results?

What are causes of abnormal EEG results?

EEGs are hard: An abnormal eeg can mean many things. Intermittent changes in eeg, like theta discharges or spikes, can be associated with epileptic seizures or other intermittent symptoms like migraine. Continuous changes, like slow background, can be an effect of drugs or internal disorders like liver or kidney disease. Changes in one spot of the head could mean damage like stroke or tumor. ...Read more

Eeg (Definition)

An electroencephaolgram (eeg) is a test that uses wires on the scalp to measure electrical activity produced by the brain. It is used to assess cerebral activity, and can be very helpful in the diagnosis and treatment of seizures as well ...Read more

Can lamictal cause abnormal EEG results?

Yes: Although Lamictal is used to treat epilepsy, a condition characterized often by abnormal eeg, it does affect the brain's electrical activity. As such it certainly does have the potential to change the eeg, just as does any other anti-epileptic drug/. ...Read more

What could cause an abnormal eeg?

Too many causes: The eeg is a measure of the electrical activity of the brain. The brain activity may run rough due to lack of sleep, medications, illness, drugs, brain damage, tumors, malformations, etc. Many findings on eeg are without explanation. Specific patterns may indicate a specific disease condition or be associated with a specific genetic disorder. Children can have strange but benign abnormalities. ...Read more

Possible reasons for abnormal EEG results for my toddler?

Many possibilities: Eeg is helpful inmany ways. Focal slowing, generalized slowing, focal seizure activity, generalized seizure activity are among the possible reasons an eeg might be considered abnormal. After age 2 the eeg of a child is similar to an adult in many ways. ...Read more

Can a severe reaction (such as swelling& high fever) to a whooping cough shot in the 50's cause an abnormal EEG and seizures in later life?

Can a severe reaction (such as swelling& high fever) to a whooping cough shot in the 50's cause an abnormal EEG and seizures in later life?

Pertussis vaccine: This would be unlikely, but anything is possible. A very rare yet serious side effect associated with this vaccine is the occurrence of seizures. The cdc reports seizures in association with the vaccine (although not necessarily causative) in one child out of 14, 000 who are immunized. This can lead to coma, brain damage and even death, but these side effects usually occur shortly after. ...Read more

My 5yr old son has had two abnormal EEG's. It's in one area of his brain, could a tumor be the cause?

My 5yr old son has had two abnormal EEG's. It's in one area of his brain, could a tumor be the cause?

Needs evaluation.: EEGs are done when one suspects seizure activity. Focal areas of seizure activity, determined by abnormal EEG may need further testing in the form of scans of the brain. You should consult a doctor/pediatric neurologist to look further into this. This is not alarming but needs further tests at least to disprove such diagnosis. ...Read more

What would make a mildly abnormal eeg?

What would make a mildly abnormal eeg?

Many causes: There are many causes of a mildly abnormal eeg from sleepiness (which can look like slowing) to medications, to medical problems causing a confusional state (delirium) to stroke and so on. Mildly abnormal eeg's are also sometimes seen in people without a definite neurological problem. ...Read more

What is the next step after having an abnormal eeg?

Do they need to catch the spike in the abnormal EEG in order to do anything about it?

Its helpful: Localization of the source of seizures and assessment of a medications ability to prevent clinical seizures can be gleaned from a single eeg study. Epilepsy is a clinical diagnosis, one best handles by a trusted epileptologist. ...Read more

After abnormal EEG (spikes&slowing) i was prescribed lamictal but didn't receive a diagnosis of anything. Does the script seem premature? Is it ok to take?

After abnormal EEG (spikes&slowing) i was prescribed lamictal but didn't receive a diagnosis of anything. Does the script seem premature? Is it ok to take?

Seizures?: An abnormal eeg suggests seizures. I see that you had an MRI of the brain which can help find any other potential cause. If you have a question about the treatment you should call the doctor to ask. Lamictal is an appropriate treatment for seizures. ...Read more

Does an abnormal EEG confirm epilepsy in you?

Does an abnormal EEG confirm epilepsy in you?

Yes and no: The eeg is a tool to be used by a trained neurologist to help diagnose epilepsy. The eeg alone is of little value. The history and examination are the important elements. Eeg recorded during a seizure can be very helpful but difficult to obtain. Baseline eeg can show abnormal activity, especially in children, even though the patient has never had a seizure. It is valuable in the right hands. ...Read more

What does a finding of "midly abnormal eeg" mean in a patient with dementia?

What does a finding of "midly abnormal eeg" mean in a patient with dementia?

Means no seizures: EEG's are best designed to look for seizures and assess some rudimentary levels of consciousness, not necessarily the same as alertness or cognitive capacity. The EEG abnormalities that you may find detailed in the report itself are likely as a result of the underlying dementia. No seizure disorder detected in this case. ...Read more

What does a finding of "midly abnormal eeg" mean in a patient with dementia?

Hard to say: If it's a change from a previously normal EEG it might mean there are some changes in how your brain processes signals. If it's your first EEG it might mean nothing. Discuss with your doctor. ...Read more

Abnormal EEG means epilepsy, or are there other people with abnormal EEG but are perfectly fine, please help!?

Abnormal EEG means epilepsy, or are there other people with abnormal EEG but are perfectly fine, please help!?

Depends on setting: While there are people with abnormal eegs who do not have any symptoms, most eeg abnormalities do suggest an underlying problem. That being said, not all abnormalities are created equal- some may simply mean that the patient was sleep deprived, while others can signify constant ongoing seizure activity. A neurologist can help put the findings in the right context. ...Read more

There are occasional high voltage sharp waves seen bilaterally. Is these the baseline for a neurologist give a diagnosis of ABNORMAL EEG?

EEG interpretation: An EEG done for very young patients is sometimes difficult to interpret. Abnormalities are common for patients less than 2 years old. It may be the pattern or size that are important. If the sharp waves are large enough though, these may be considered abnormal. ...Read more
