What is epilepsy?

Epilepsy is currently one of the most commonly diagnosed neurological disorders. It is characterized by the occurrence of spontaneous seizures. About 30% of patients have drug resistant epilepsy, which means that seizures cannot be controlled by medication. In such cases, seizure forecasting systems are vitally important, since they allow patients to avoid dangerous activities and bring themselves in a safe environment before a seizure starts.

What causes epilepsy?

Anyone can develop epilepsy during their life, but it’s more common in young children and older adults. Also epilepsy can caused by traumatic brain injury; scarring on the brain after a brain injury (post-traumatic epilepsy); serious illness or very high fever; stroke, which is a leading cause of epilepsy in people over age 35; other vascular diseases; lack of oxygen to the brain; brain tumor or cyst; dementia or Alzheimer’s disease; maternal drug use, prenatal injury, brain malformation, or lack of oxygen at birth; infectious diseases such as AIDS and meningitis; genetic or developmental disorders or neurological diseases.

Living with epilepsy, what to expect?

Epilepsy is a chronic disorder and it has different manifestations that depend on the type of epilepsy. In common cases epilepsy may include:

  • risk of permanent damage or death due to severe seizures that last more than five minutes (status epilepticus)
  • risk of recurring seizures without regaining consciousness in between (status epilepticus)
  • sudden unexplained death in epilepsy, which affects only about 1 percent of people with epilepsy

What can I do to reduce risks?

  • Keep a seizure diary to help identify possible triggers so you can avoid them.
  • Wear a medical alert bracelet so people know what to do if you have a seizure
  • Teach the people closest to you about seizures and what to do in an emergency.
  • Seek professional help for symptoms of depression or anxiety.
  • Join a support group for people with seizure disorders.
  • Take care of your health by eating a balanced diet and getting regular exercise.


HELi is a complex solution for people who suffer epilepsy. It provides the opportunity to forecast seizures before they occur. Epilepsy is one of the world’s most common neurological diseases, affecting more than 40 million people worldwide. Epilepsy can have a broad spectrum of debilitating medical and social consequences. Development of devices that incorporate algorithms capable to detect early onset of seizures or even to predict them is an area of great interest. Many researchers are working to develop an automated tool which easily analyses the EEG signal and revels important information present in the signal.

How does HELi work?

Our solution consists of three main parts: the wearable EEG device; the operational system that analyze data in real time; mobile app that alert you and relatives about seizure upcoming.
