EEG or electroencephalography
It is said to record the electrical activity of the brain, which is used to diagnose brain problems such as stroke seizures. This method is done by placing electrodes on the surface of the human head, amplifying and removing noise, printing the signals and finally analyzing them. This method greatly helps doctors in diagnosing problems related to the electrical activity of the brain, such as seizures. The EEG test is also used to check how other brain disorders affect the electrical patterns or brain waves. To perform an EEG test, a special cap with electrodes is used to detect the electrical activity of the brain. This test is considered one of the best diagnostic tools for diagnosing seizure disorders, including epilepsy. In some cases, specialists use this method along with other diagnostic methods such as CT scans or MRI. Brain cells communicate with each other using electrical signals, and some brain disorders can lead to disturbances in brain signals. This test measures changes in the electrical activity of the brain, and in this way it helps doctors in diagnosing brain disorders a lot.
How is an EEG test done?
- An EEG test is usually short and is often done in an outpatient clinic. An experienced technician will monitor the person during the test.
- For this test, the person sits in a chair or lies on a bed and the technician places a cap containing 16 to 25 flat metal discs called electrodes that measure the brain’s electrical activity on the person’s head.
- The technician measures the person’s head and uses a wax pen to mark the location of the electrodes. Then, he or she applies a substance called conductive gel between the electrodes and the skull to make sure the electrodes receive a strong signal from the brain.
- During an EEG test, the room should be quiet and dark, and the technician will ask the person to do things like breathe Slowly, looking at a point of light that causes abnormal electrical signals.
- The person should not have consumed caffeine for 8 hours before this test.
- This test records the electrical activity of the brain and determines if there are any abnormalities.
- If a seizure occurs during an EEG test, the normal brain activity is disrupted and the technician can see abnormal waves. These patterns are very helpful in diagnosing epilepsy.
