What Happens When My Child Has an EEG?
Understanding an EEG
An EEG, or electroencephalogram, is a non-invasive test used to measure the electrical activity in your child's brain. This procedure can help diagnose conditions such as epilepsy, sleep disorders, and other neurological issues. Knowing what to expect can ease any anxiety you or your child might have regarding the test.Preparation Before the EEG
Your child may be asked to follow certain guidelines before the EEG. This can include avoiding caffeine, as it may affect the results, and ensuring their hair is clean and free from any products like gels or oils. Sometimes, a sleep-deprived EEG is needed, in which case instructions will be given for reducing your child's sleep the night before the test. Bringing a comforting toy or blanket is often encouraged to help your child relax during the procedure.During the EEG
Upon arrival, a technician will explain the procedure to both you and your child, helping to ease any concerns. Small electrodes will be attached to your child's scalp using a special paste. These electrodes are painless and simply record brain waves. Your child can sit or lie down comfortably as the EEG is conducted. They might be asked to close their eyes, breathe deeply, or look at flashing lights to record different brain activities. The entire process can take from 30 minutes to a few hours, depending on the type of EEG being performed.Post-EEG Care
After the EEG, the electrodes and paste will be removed. Your child can return to their usual activities immediately, and there are no side effects from the test. In some cases, any residual paste can be washed out of their hair at home.Receiving the Results
The EEG results are not typically available immediately. A specialist will need to analyze the recordings and provide a report to your child's doctor. This process can take a few days. Once the results are in, your doctor will discuss the findings and potential next steps with you.Final Considerations
Rest assured that an EEG is a standard and safe procedure used widely across the National Health Service (NHS) and private healthcare providers in the UK. Keeping calm and reassuring your child can make the experience more comfortable for them. If you have any concerns or questions either before, during, or after the EEG, don’t hesitate to speak with the healthcare professionals involved.Frequently Asked Questions
What is an EEG?
An Electroencephalogram (EEG) is a test that detects electrical activity in the brain using small, flat metal discs (electrodes) attached to the scalp.
Why does my child need an EEG?
An EEG can help diagnose conditions such as epilepsy, sleep disorders, and other brain-related conditions by monitoring brain activity.
How should I prepare my child for an EEG?
Ensure your child has clean hair with no products such as gels or sprays. Follow any specific instructions from your healthcare provider regarding sleep and meal schedules.
Can my child eat before the EEG?
Yes, your child can eat before the EEG unless instructed otherwise by your healthcare provider.
What will happen during the EEG?
Your child will be asked to lie down and relax while electrodes are attached to their scalp. The test is painless and will take about 60 to 90 minutes.
Will my child need to be sedated for the EEG?
Sedation is typically not required for an EEG. However, for younger children, healthcare providers might suggest a sleep-deprived EEG to ensure they are tired enough to rest during the procedure.
How long does an EEG take?
An EEG usually takes around 60 to 90 minutes, though some tests may be shorter or longer depending on the reason for the EEG.
Is an EEG painful or uncomfortable for my child?
An EEG is a painless procedure. The electrodes attached to the scalp do not cause any discomfort.
What should my child wear to the EEG appointment?
Your child should wear comfortable clothing. Avoid clothes with metal, such as zippers and buttons, as metal can interfere with the test.
Can I stay with my child during the EEG?
Yes, parents or guardians are usually allowed to stay with their child during the EEG to help keep them calm and comfortable.
Will my child need to stay in the hospital after the EEG?
In most cases, your child will not need to stay in the hospital and can go home immediately after the test.
What happens if my child moves during the EEG?
If your child moves during the EEG, the technician may pause and readjust the electrodes. Movement can cause artifacts that may affect the quality of the recording.
How is the EEG data used?
The EEG data is analyzed by a neurologist who looks for abnormalities in the brain activity patterns. The results can help with diagnosing and planning treatment for various conditions.
When will we get the results of the EEG?
EEG results are typically available within a few days. Your healthcare provider will discuss the findings with you and explain any next steps for treatment if necessary.
Are there any risks associated with an EEG?
EEGs are very safe and non-invasive. There are no significant risks associated with the procedure. Some children may feel a bit anxious, but there's no physical harm from the test.
