An EEG test, or electroencephalogram, is a medical procedure that measures the electrical activity of your brain.
Understanding the EEG Test
How it Works
- An EEG test uses electrodes attached to your scalp to detect the tiny electrical signals produced by your brain cells.
- These signals are then recorded and displayed as wavy lines, which doctors can interpret.
- The procedure is painless and does not require shaving any hair.
Why is an EEG test Performed?
- EEG tests are often used to diagnose and monitor various brain conditions, such as seizures, epilepsy, sleep disorders, and brain injuries.
- The EEG helps doctors understand brain function and identify any abnormal patterns.
- It's also used to monitor brain activity during surgeries and to diagnose comas.
What to Expect During an EEG Test?
- During an EEG test, small electrodes are attached to your scalp with a special paste.
- You may be asked to relax and remain still.
- The test usually takes between 20-60 minutes.
- You can usually go home immediately after the test.
