In a healthy person, the activity of nerve cells in the brain is precisely matched by electrical and chemical signals. In patients who suffer from epilepsy, this balance is temporarily disturbed.
This leads to pathological, short term and attack-like discharges. Many nerve cells subsequently send signals suddenly and uncontrollably, creating a kind of “thunderstorm in the brain”. This spreads and excites individual brain areas or even the entire brain in an unnatural way. Depending on which areas are affected, the symptoms and manifestations of an epileptic seizure are different.
The NEMOS® therapy device consists of a simulation unit that generates electrical impulses and is about the size of a conventional smartphone. This is connected to a special ear electrode, which is worn like an earphone. The pulses are delivered via the ear electrode through the skin to a branch of the vagus nerve and forwarded to the brainstem. From there, as with the invasive vagus nerve stimulation, higher centers of the brain are activated, triggering an anticonvulsant effect.
