EEG

An EEG (Electroencephalogram) is a test that checks the electrical activity of your brain.

What to Know:
1.⁠ ⁠Why It's Done: It helps find problems like seizures, epilepsy, or other brain issues.

2.⁠ ⁠How It Works:
- Small sticky pads (electrodes) are placed on your scalp.
- The test is painless and takes 20–40 minutes. Sometimes, it may be longer if done while you're asleep.

3.⁠ ⁠Getting Ready:
- Wash your hair but don't use oils or sprays.
- Avoid caffeine on the day of the test.
- Follow any special instructions from your doctor, like staying up late for certain tests.

4.⁠ ⁠Is It Safe? Yes, it’s completely safe. No electricity enters your body.

5.⁠ ⁠What It Can't Do: It doesn't show the structure of your brain, and sometimes the results may not explain your symptoms.
