Preparing for an EEG: Tips from SugarLand Neurodiagnostics

Dec 20, 2025

Preparing for an EEG, or electroencephalogram, can be a simple process when you know what to expect. At SugarLand Neurodiagnostics, we want to ensure that your experience is as smooth and stress-free as possible. Here are some tips to help you prepare for your EEG appointment.

Understanding the EEG Procedure

An EEG is a non-invasive test that records electrical activity in the brain. It is often used to diagnose conditions such as epilepsy, sleep disorders, and other neurological issues. Knowing what the procedure involves can help ease any anxiety you might have.

Before Your EEG

Proper preparation before your EEG can make a significant difference. Here are a few steps to consider:

  1. Avoid caffeine: Refrain from consuming caffeine at least 8 hours before the test, as it can affect the results.
  2. Wash your hair: Ensure your hair is clean and free of any products like gels or sprays. This helps the electrodes adhere better to your scalp.
  3. Get a good night's sleep: Lack of sleep can influence the EEG's outcome, so aim for a restful night's sleep before your appointment.

During the EEG

The EEG test is straightforward and generally lasts about 30 to 60 minutes. During the test, electrodes will be placed on your scalp, and you'll be asked to relax and remain still. You may be asked to breathe deeply or look at a flashing light as part of the test.

What to Bring

To ensure a comfortable experience, consider bringing these items:

  • Comfortable clothing: Wear loose-fitting clothes that will keep you comfortable during the test.
  • Reading material: You might have some waiting time, so bringing a book or magazine can keep you entertained.
  • List of medications: Make sure to bring a list of any medications you're currently taking.

After the EEG

Once the test is complete, you can usually resume normal activities immediately. It's a good idea to have someone drive you home, especially if you were sleep-deprived before the test. Your doctor will discuss the results with you at a follow-up appointment.
