General questions 

+ What does epihunter do?

Epihunter uses digital technologies to create new solutions that make epilepsy matter less in daily life. Our focus is on absence epilepsy as this causes silent, difficult to notice seizures that have a huge impact on day to day life.

+ How did epihunter originate?

“Dad, you work in digital, can you create a light that turns on when my brain switches off?” This question, from a son to his, father led to this new start-up. Find out more in our blog.

+ Is this the only epihunter product?

Currently we are focusing on this product only. Epihunter ultimately wants to offer solutions for day-to-day challenges for people of all ages with all forms of epilepsy. From conversations with people with epilepsy and experts, we are already aware of a few needs for which we have future potential solutions in mind. Do not hesitate to send us your suggestions!

+ In which regions is epihunter available?

Currently, epihunter is only available in Europe, and via our reseller in Australia & New Zealand. We offer FREE shipping with online tracking.

Do you live outside of these regions? Subscribe now to our newsletter and we'll keep you informed on future availability in your region.

+ Can epihunter also be used in other locations (e.g. at home)?

Yes, epihunter can be used wherever you have access to a WiFi network. Do note that the device does not need continuous WiFI access but that it eventually would need it to sync results. Hence, the most important is the access to an Android phone (can be SIM-free) with a continuous Bluetooth connection between the EEG headset and the phone.

+ Can an adult with absence seizures also use epihunter?

Yes, epihunter can be used by adults at home, work or wherever is valuable. Epihunter would work for anyone from the age of 4. 

+ Living in Australia or New Zealand?

Epihunter is since July 2020 also available in Australia and New Zealand through our partner Seizure Alert Australia. Are you based in one of the two countries, you can order epihunter here


About the epihunter subscription

Any questions in regards to payment? Contact us!

+ Why is epihunter offered as a subscription?

Epihunter main components are the software we continuously update. The subscription includes access to two smartphone applications and our cloud platform:

  • epihunter Core smartphone app (for Android) runs our complex algorithm to detect, signal and video record seizures in real time
  • epihunter Companion smartphone app (for Android & iOS) provides an overview of seizures, notes and videos,
  • secure cloud platform that interacts with the smartphone apps and saves all historical data in a secure way.

The EEG headset (retail value approx. £149) is offered as a loan for use so you don't have to worry about getting stuck with an expensive device. So just to be clear: The EEG headset only collects the raw EEG data and does not do anything useful without our smartphone apps and algorithm.

The smartphone apps and cloud platform are continuously being improved and new features are added frequently. All updates are included in the subscription

Yes, epihunter can be stopped at any time after the first 3 months of subscription.

+ Can I charge the smartphone while using epihunter?

Yes. For easy charging, the smartphone can be placed in landscape in the supplied smartphone holder to allow charging cable access.

+ What type of seizures can epihunter detect?

Epihunter focuses only on the detection of absence seizures and focal impaired awareness seizures (as from 3 seconds). Epihunter will not detect motor (or convulsive) seizures.

More technically, epihunter will work if your (clinical) EEG shows specific spike or discharge patterns in the Fp1-F7 derivation. This is something that you could ask your neurologist.

Find more information on our blogpost: EEG technology clarified.

+ What do the different module notifications mean?


Blue light

Module is turned on and is connected to the smartphone

2 beeps

When the module turns on or when the sensors are well connected with the forehead

Red & blue light

Module is turned on but has no connection with the smartphone

1 beep

Module is turned off

4 beeps

Module battery is empty

Red light Device is charging

+ How do I enable the video functionality?

Check out our How to-movie for enabling epihunter Video or follow the steps below:

1) To enable/disable the video functionality: Go to Settings and change the "Video" toggle.




2) You might have to grant epihunter Core access to e.g. record & store videos on your phone. 

3) When you see a green dot in the top left corner on the black home screen you have correctly set up video!




4) Press the green dot for a preview. This is a good way to check that the person with epilepsy is in the picture and hence that the camera will capture the seizures. Use the smartphone holder from your welcome package!

5) Seizure videos will now be automatically recorded. Would you like to manually record a seizure video? Simply press the "Log seizure start" button. Don't forget to press the red "Log seizure end" button to end the seizure recording. 

6) Use the separate epihunter Companion app to access and watch your recorded videos.

For privacy reasons we advise to only use the video functionality at home.

About the EEG headset

+ How to unbox the EEG headset?

We made a short step-by-step manual for how to unbox the BrainLink EEG headset. It also shows you how to find the charging cable and a handy travel bag.

+ How to charge the BrainLink EEG headset?

+ How to turn on the EEG headset?

+ What is the battery life for the BrainLink headset?

The battery life of the headset is estimated at 4 hours. We recommend charging the headset every night for optimal use.

+ How is it possible that epihunter only uses a small headband, yet in hospital many electrodes are being glued to my head?

This is a great question we received on facebook.
  • In short: With epihunter we are only looking to answer the question "Is there an absence seizure?" while in hospital there are many more questions the EEG is used for.
  • A bit longer and more technical: Hospital EEG provides detailed information on what happens in the different parts of the brain. Yet, absence seizures are generalized throughout all parts of the brain which means that to detect them it doesn't matter where on the skull you place the sensors. This means that we can do with only 2 sensors to the forehead (Fp1 and F7 to be precise) and by using machine learning data analysis we can filter out a lot of noise to detect the specific patterns of an absence seizure.

+ Can I use epihunter Companion app without an epihunter subscription or EEG headset?

Epihunter Companion is a free app in addition to the epihunter solution to detect epileptic absence and focal onset impaired awareness seizures. 

You can download epihunter Companion for free in the Apple App Store or Google Play Store. Yet, in order to access any data, epihunter Companion needs to be linked to a valid epihunter subscription.

Once linked you can fully enjoy the benefits of epihunter Companion and have access to the seizure information from the person using the epihunter solution and headset for absence seizures.
