Epilepsy
Epilepsy is a chronic brain illness affecting around 50 million people in the world. It is characteristic for its recurring seizures revealing brief episodes of involuntary tremors upon either part of the body (partial seizures) or the entire of the body (generalized seizures). They are sometimes accompanied by a loss of consciousness and loss of bladder or bowel movement control.
Those seizures are the result of excessive electrical shocks in a group of cerebral cells. Those shocks can happen in various parts of the brain. The seizures can vary in intensity, ranging from brief episodes of losing focus or small muscular jolts, to severe and lasting convulsions. Their frequency is variable, going from less than once a year to several times a day.
If a patient presents a treatment-resistant epilepsy, they will be offered stimulation of their vagal nervous system.
