Which condition is often treated with a vagal nerve stimulator as an alternative to medication?

A vagal nerve stimulator is primarily used in the management of chronic seizure disorders, particularly in cases of epilepsy that are refractory to traditional antiepileptic medications. This device is implanted under the skin and delivers electrical impulses to the vagus nerve, which can help reduce the frequency and severity of seizures.

The rationale for using vagal nerve stimulation (VNS) in chronic seizure disorders stems from the role that the vagus nerve plays in modulating brain activity and influencing seizures. While it is not a cure, VNS offers a beneficial alternative for patients who do not respond optimally to medication, enhancing their quality of life.

In contrast, conditions such as severe migraines, chronic pain, and asthma attacks are not typically treated with vagal nerve stimulators. Though there are various treatments available for these conditions, VNS has not been established as a primary or alternative therapy for them.
