You DON't have to limit your activities or give up your independence anymore - THANKS TO SEIZURELINK! 

Discover how SeizureLink Users and their Caregivers live fuller lives, get some relief, and sleep a little better with the new standard in consumer alerting systems.

Buy Yours NowIf you're a caregiver for someone with sustained tonic muscle contractions, then you know what it's like to lie awake at night waiting, to give up sleeping in your own bed, and to stay within visual sight of your loved one at all times. 

And if you are an adult, you worry how tonic events will impact your ability to do your job, your capability to care for your children without supervision, and your freedom to experience a regular social life. 

In other words, your zone of independence is small, and you limit activities because you just can't predict when the next event will happen. 

With this in mind, it could mean missing out on play dates, sports, and even that rite of passage: living alone.

Now, there may not be a cure for this limiting disorder---yet.

However,  there is a way to regain your independence and live a fuller life.

What would that look like for you...for your family...and for your life?

Imagine a world of greater self-sufficiency---saying "yes!" where you now have to say "no"- and still being connected to the help you need, when you need it most.

SeizureLink is your key to this new and bigger world.

Before you read the science behind SeizureLink and how it works, let's get down to basics.

Linda and Kingston


"Before SeizureLink I was just a big ball of worry, constant worry. My son was having a lot of seizures in his sleep. How could I know if he was in trouble? How would I be able to help him? I tried other devices, things that would alert us if he seized, but none of them even came close to doing what SeizureLink does for us. The first night we put it on him, it alerted us that he was having a seizure at 5:50 am. I immediately felt relief. We are so thankful! " - Linda

How does SeizureLink change lives? Our customers say it best:

"I don’t have to worry so much while I am alone with my kids and worrying that they will be alone and afraid. I like that it will alert a caregiver immediately, so they can get to me quickly. They can help me, but they can also comfort my kids and help them, so they won’t be as scared. Before I used the SeizureLink System I felt like I was locked up in a little shell, if that makes sense. Now I have more freedom – a lot more freedom. And it feels really good"  -Chris Christalle2


 "The energy it takes to be constantly on alert is exhausting, and it’s a very stressful way to live - just waiting for something to go wrong. SeizureLink has given me more confidence and reassurance. It’s nice to know that if something happens to me, my husband/caregiver will be notified and can help me, if needed. SeizureLink has been helpful in allowing me to feel more independent." -Christalle 




Because of SeizureLink I am more aware of my seizures and how often the debra bartonhappen. I didn’t really have that before. I also feel more comfortable because I know that if I have a seizure, someone will be there to help me, and I won’t be by myself. That is a pretty big deal to me” – Debra






"I have a lot more privacy now because my family isn't worried all the time. I don’t have to have someone with me all the time. I can also do the things I love to do, like dance! I can pursue that and I don’t have to worry, so it’s better." - Sheridan



Increase your independence, gain peace of mind for the safety of your loved one, and be able to think about something other than the next events for a change - without feeling guilty


The Monitor alerts Caregivers using the SeizureLink App. After the Monitor alerts with lights and an audible alarm, the SeizureLink System uses Bluetooth connectivity to send alerts to the Wearer's mobile device, and then a phone call and alerts are sent to Caregivers via the smartphone app.  Wearers can have up to 10 Caregivers and Caregivers can have up to 4 wearers. 

 A Powerful Monitor That Weighs Only 1 Ounce

The SeizureLink Monitor is a small and lightweight device that only weighs 1 oz.  It can easily be adhered to the belly of the biceps on adults and children with an arm circumference of 6 inches. It’s discreet, and non-invasive so it can be integrated into any busy or active lifestyle without worry. Its dimensions are 2.5 inches by 1.7 inches by 0.6 inches.  Comparatively, it is roughly the size of a sugar packet.

Frequently Asked Questions 

The SeizureLink algorithm is muscle activated, not motion activated. It recognizes an electrical muscle signal. Since we recognize this signal on the surface of your skin, it is more properly known as surface electromyography, or sEMG. Because it is recognizing sustained tonic muscle signals, the SeizureLink algorithm can sense when the muscle clenches and tightens. And it does it fast — on an average of 9 seconds versus 30 seconds or more for other alerting watches and devices that rely on waiting for the body to shake. Measuring sEMG is what accounts for its high accuracy of 94%, low false alarm rate of 0.67 per day and only 1 false alarm per 82 nights.* The Monitor alarms and sends out a real-time alert to the app on a mobile device. This alert goes out to your selected caregivers so that you can get help as soon as possible. The event gets logged into a seizure diary on your phone so that you can add details to it later and share with your caregivers.
The SeizureLink algorithm sends alerts when it recognizes sustained tonic muscle activity that lasts for at least 9 seconds. The Monitor sends alerts to caregivers when it senses prolonged tonic-muscle activity.
The SeizureLink algorithm uses surface electromyography, or sEMG, which is the most accurate and fastest way to know when a sustained tonic muscle contraction occurs. What makes it unique is that it is muscle activated - the SeizureLink algorithm can sense when the muscle clenches and tightens during tonic muscle activity. It’s also different because it’s the fastest alerting system- on average, alerting Caregivers within 9 -12 seconds versus 30 seconds or more for motion devices that rely on waiting for the muscles to shake. 
The SeizureLink Monitor is discreet and durable. It weighs only one ounce and it’s roughly the size of a sugar packet. Its dimensions are 2.5 inches tall, 1.7 inches in width and a depth of 0.6 inches. It can be worn by children with an arm circumference of at least 6 inches. 
The SeizureLink Pack is $499.  Electrode patch subscriptions start at as low as $1.17 per day. Go here for more info on pricing. There are no additional monthly monitoring fees. 
Yes, we do! We offer 2 interest-free options through our partner, Klarna. Go here to learn more about our payment plan options. 
Yes. There are several status alerts to help you manage your SeizureLink System and experience. These include:
  • Out of Range
  • Loose Electrode
  • Low Battery notification so you know when it’s time to swap out the battery. The battery may be changed while the SeizureLink unit is on the biceps.
  • Wearer connection status on the Caregiver App so you know if your Hero is on the System and linked or not.
It’s important to know that the Monitor connects to the Wearer’s app via a Bluetooth connection. Both the Wearer and Caregiver’s phones must be connected to the internet either via a cell phone or a solid internet connection. After the SeizureLink Monitor alerts to an event with lights and an audible alarm, if the Monitor is connected to the wearer’s phone via Bluetooth, the phone app activates the alerts on the wearer's mobile device. If the Wearer’s cell phone is connected to the internet, the Caregiver’s mobile device will activate with a phone call and App alerts. Remember both an active Bluetooth connection and internet connections must be on to transmit an alert from the Wearer’s Monitor to the Caregiver’s App.

Yes. sEMG is a muscle signal. To recognize it accurately, the SeizureLink Monitor must be placed on the biceps. For proper placement and alerting, it must be placed right on top of what is called the ¨belly¨ of the biceps. 

Zero. There is no additional charge for monitoring. Alerts, notifications, and Seizure Diary Reports are included at no additional charge.

We offer 2 options to replenish your electrode supply so that you never run out.

1. Pay-As-You-Go let's you buy the quantity you want with no commitment. 

2. Auto-Renewal Plans offer the best pricing and provides for automatic shipping at 2, 6 or 12-month intervals. 

With both options, you can save by buying more boxes of electrodes in a single purchase.

Typically, insurers do not reimburse for alerting devices, but some insurers may cover some or all of the cost. Please check with your insurance carrier. We do not accept insurance filings for this product.
The SeizureLink app Works on Android devices with 5.0 Lollipop (API level 21) and iOS devices with 10.0 or later. It works on both smartphones and tablets. Bluetooth and internet connection are required for the app to function and the app must remain open and running in the background on the wearer's mobile device. Internet can be wi-fi or cellular.

The SeizureLink product initially will only be available in the U.S. We will announce our plans for other countries in 2019.

The Bluetooth range is 50 yards in an open space. If the SeizureLink Alerting System is out of Bluetooth range, an alert will sound on the SeizureLink App on the Hero’s mobile device, and real-time alerting will be interrupted.

No. The SeizureLink System is not a medical device, nor is it cleared by the FDA for medical device application. It is not cleared to monitor, treat, diagnose, or prevent a medical condition, nor is it intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment or prevention of disease.

"We were part of the trial study. SeizureLink is an excellent product for detecting tonic clonic seizures for your loved one. The alert system works very well with the app and it can be used while you're at home or while you're away from your loved one. The team works very hard to keep updates coming quickly. I highly recommend it as a great tool to bring fast help and peace of mind for your loved one."



"SeizureLink delivers accurate results quickly to alert caregivers when a tonic-clonic seizure has occurred. It has given me reassurance and more independence. I recommend this device over other seizure alert devices I've tried in the past, due to accuracy and fast alerts." 


Lightweight and simple to use. My tactile-defensive daughter doesn't notice she's wearing it.

SeizureLink is personal to us.

When a young boy suddenly developed nocturnal seizures, his mom spent many anxious nights watching him sleep, afraid to leave him alone because of the unpredictable onset of his events. His family tried all available seizure detection technologies without success.

Along with a group of seasoned medical professionals, the family founded Brain Sentinel whose primary goal was to help families when a loved one suffers.

Now, Brain Sentinel Consumer Systems is making sEMG technology available in the home. Our goal is to provide products that offer the most accurate and quickest link between an event occurring and help arriving. We know how much families need assistance.

We get it. And we’re here to help.

The System is not a substitute for proper supervision, inspection or observation of the wearer.  Always assure the wearer of the System has proper supervision. In order for the SeizureLink unit to alert and connect with wearers, caregivers, and other designated individuals (“Alertees”); Alertees must assure that the SeizureLink unit is charged appropriately, is Bluetooth connected to the wearer’s mobile device, caregiver’s or other designed individual’s mobile device, and is connected to a cellular network. The SeizureLink unit alerts only when the device is properly placed on the biceps muscle and is connected as communicated above and in accordance with the procedures outlined in the SeizureLink User Manual. Alertees should take caution during a storm, an Act of God, or other events outside the control of Brain Sentinel. Alertees should check their connections periodically to assure the connection is established between the SeizureLink unit and their mobile device(s). If the unit is not connected properly, Alertees should not expect the SeizureLink unit to alarm during muscle activation.
