Rest Easier Knowing That SeizureLink Will Be There For You or a Loved One…Day or Night!


Fast & Accurate Alerting System - Made Simple!

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

Thanks to rapid advancements in technology backed by research, we’ve created the new standard in personal alerting systems based on muscle, not motion: The SeizureLink System. 

The SeizureLink System was designed to do one job: to more accurately and quickly connect you with help. Using muscle, not motion, the SeizureLink System is based on surface electromyography (sEMG). This revolutionary new alerting system sends out an alert for sustained tonic muscle contractions lasting at least 9 seconds. This means that SeizureLink may set off an alert before shaking occurs to help you quickly recognize what’s going on.

And Here is What People Had to Say After Seeing it in Action…

"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 

NOTHING is faster than sEMG...

sEMG is the new standard in alerting systems because it recognizes an electrical muscle signal known as electromyography. Since this occurs on the surface of your skin, it is more properly known or referred to as surface electromyography or sEMG. And the greatest benefit of sEMG? It’s super fast! Alerts usually are triggered around 9 seconds versus 29 seconds or longer for other devices that solely rely on motion.

...And our accuracy is second to None

sEMG is what accounts for The SeizureLink System’s astonishingly high accuracy rate of 94%, low false alarm rate of 0.67 per day and only 1 false alarm per 82 nights.*

"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

Our Story (Will Be Expandable)

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 give families help when a loved one suffers from generalized muscle tension or spasms.

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.

Disclaimer (will Be Expandable)

The SeizureLink™ System monitors for muscle activation and it 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. Use of SeizureLink is not a substitute for professional medical advice concerning your condition or medical treatment for you. Please consult your physician or your healthcare provider to ask questions, discuss your condition and the options for you. 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 that during a storm, an Act of God, or other events that is 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.

What is the SeizureLink System?

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.
