A machine called an electroencephalogram (EEG) is used to capture brain activity. Your brain constantly emits minute electrical signals. During an EEG exam, tiny sensors called electrodes are put on your scalp. Wires connect an EEG device to the electrodes. The adhesive or paste that is used to attach the electrodes is a particular paste glue. After the electrodes are taken out, your hair can still contain a lot of glue. The adhesive may be easier to remove with the help of a hair conditioner. The electrodes capture the electrical signals coming from your brain and save them on a computer.
The wavy lines in the electrical signals are the patterns of your brainwaves. Only the brainwave patterns present at the time of the exam can be determined by the EEG test at Seer Medical. At various periods, your brainwave patterns could change. A highly skilled professional known as a clinical neurophysiologist can identify it if your EEG test indicates a brainwave pattern that differs from the majority of people. Some of these patterns imply a high likelihood of epilepsy.
When do EEG tests take place?
Sometimes an EEG is used to assess if a person has non-convulsive status epilepticus. Without an EEG, non-convulsive status epilepticus may not be identified as a seizure even though it can change a person’s awareness or cause disorientation. Doctors can choose the best course of treatment and make the correct diagnosis with the help of the EEG data. A medical professional with expertise in EEG interpretation should always interpret them. This is due to the fact that one of the most frequent reasons why patients receive an inaccurate diagnosis is improper EEG interpretation.
Where do EEG exams take place?
An EEG is frequently conducted in an outpatient clinic at a hospital. People who have epilepsy have expressed to us how helpful having a partner throughout the visit was. There is a slight chance that you will experience a seizure while undergoing the test, and the approach can be taxing for some people. It’s a good idea to consider your return home after the appointment. You might be required to bring a tiny piece of recording gear home with you. You will see an example of this.
A person with epilepsy may only experience odd electrical activity in their brain during a seizure. Your brain could function normally for the remainder of the period. If your EEG test reveals no abnormal activity, it simply means that there was no brain activity associated with epilepsy at the time of the test. The idea that your brain behaves strangely at other times is not disproved by this.
