Having an EEG at Evelina London – video transcript

Kayleigh: My name is Kayleigh and I've come to the Evelina Children's Hospital to have an EEG test. When I walked into the Evelina Hospital it felt like it was just for children because it had loads of toys and it's very colourful. I came to have an EEG to measure my brain waves.

Mum: How are you feeling?

Kayleigh: I was feeling a little bit anxious but when I had it done it was okay. When Maria (clinical physiologist) came in she was very nice to me, she was very friendly, and she said the EEG would show pictures of my brain. I think that's quite amazing.

Maria: Did you have to wake up very early? So Mum, you can sit over there and Kayleigh I need you on this one. The big and comfy one is for you. So you're here today so I can record your brainwaves, OK? It's really easy to do, it doesn't hurt.

Kayleigh: First Maria measured my head and when she put the crayon on me, it tickled a little bit. Then she said I could look at the iPad, I didn't realise I'd get to play games while it was happening. After that Maria put disks on with a paste and it was very sticky, it didn't hurt at all. It felt funny when I had the wires on because every time I moved I realised there was a wire on my head. When I put the netted hat on I looked really funny.

Mum: Wow! Cool hat Kayleigh!

Kayleigh: Maria asked mummy to give me some medicine, it was okay it tasted a little bit like strawberries.

Maria: You're doing really well so far and now I need you to keep still and close your eyes for me.

Kayleigh: Maria asked me to open and close my eyes, then she asked me to blow on a colourful windmill. I blew as hard as I could. Maria asked me to lie on the bed, she asked me to look at some flashing lights and it looked a little bit like a disco. I didn't really like it but it didn't hurt and it didn't take very long, then mummy sat next to me I got comfortable and went to sleep. When I woke up I was feeling a little bit sleepy still, finally Maria took the wires off my head and cleaned my hair with a cotton ball. I could still feel some sticky stuff in my hair. Maria said when I got home I could wash my hair and it would all come out. I'm glad it's done and I feel fine. Now I'm going to go home on the train. Goodbye!


Home video EEG telemetry

If you or your child need to have a home video telemetry EEG, the test will be set up at Evelina London. You will then be sent home with the recording equipment.

Find out what to do to carry out home video telemetry, and see tips to make the test successful.

Home video EEG telemetry at Evelina London Children's Hospital – video transcript

Dr Sushma Goyal, consultant paediatric clinical neurophysiologist: When a child is having fits, faints and funny turns, finding the right diagnosis can be challenging. One way is to monitor the brainwaves for the child along with the video. This is called video EEG telemetry.

Claire: I'm Claire and me and my son Ryland have come along to the Evelina hospital today so he can have a home telemetry. I'm not sure what to expect but we'll see how it goes.

Dr Goyal: Traditionally it's been done in hospital but now we can offer the service at home. The child comes in for an appointment just like a standard EEG. We take a full history, carry out some checks and then make a short recording. We show you how to use all the equipment and give you instructions and a contact number to call if you have any problems. We show you how to press a button and fill in a sheet if your child has an event. You will have a small recorder which goes in a bag, and a camera which goes in a protective briefcase. We'll talk to you about how you're going to get home with all the equipment.

Claire: It's great because they give you a number that you can call if you get stuck or you're not sure about something and a lot of information how to do it as well. So that really helped for me if I'm honest, just in case something went wrong.

Dr Goyal: Once you get home you'll need to set up the camera. The first step is to plug it into a wall socket. Next open the view panel, press the start/stop button at the back of the camera. Make sure you see a red light on the viewing panel. Attach the infrared light to the top of the camera. Keep the video view panel open. Put the camera in a position where you can see your child from head to toe. You don't need to zoom in or out. If you accidentally close the screen, reopen it and press start/stop to start recording again. If your child moves into another room bring the camera through and reposition it.

Claire: Ryland's the kind of kid you can't keep still, so it's amazing that we can have it done at home that he can still run around it's just a normal day for him and it makes no difference and that's amazing.

Dr Goyal: If you're recording for more than one night we'll give you new batteries for the recorder and the infrared light. We'll tell you what time to change them and we'll ask you to set a reminder. At night you will need to press the night shot button on the camera and turn on the infrared light. This makes sure we can see your child clearly, even in the dark. Don't worry if the bandage comes off or a wire becomes loose, we can still get a good recording. We'll tell you how long to record for. When the recording is finished cut through the wires and take off the bandage. Then soak your child's hair in warm water and shampoo, then you can take the discs off and gently work off the paste. Put all the equipment away and don't forget to put in the sheet. We'll arrange for a courier to collect it. Here are some helpful tips: Make sure the camera is recording. Try not to keep starting and stopping the camera. Try to keep the child in full view of the camera. At night remember to switch on the night shot function and turn on the infrared light. Remember to change the batteries of the EEG recorder and infrared light. Press the event marker to record any events and record them on the sheet given. Make sure you don't come in front of the camera. Don't position your child in front of a light or a window. The results are usually ready within four weeks.

Claire: Yes it's daunting but I promise you I found it quite easy after the Evelina showed me how to do it properly, and once you turn it on once it's, honestly it's really easy. Since we've been home he's been on the trampoline, he's been on the slide, he's been running around, he's been doing every single thing that he does on a normal day and it hasn't stopped him. That's the best part.
