Final answer:
A patient with epilepsy is likely to have a vagus nerve stimulator (VNS), a device that helps control seizures when medications are not sufficient.
Step-by-step explanation:
A patient with epilepsy is likely to have a vagus nerve stimulator (VNS). Epilepsy is a neurological disorder characterized by recurrent seizures, which can sometimes be resistant to medication. For individuals whose seizures are not adequately controlled by anticonvulsant medications, a VNS may be implanted to help reduce the frequency and intensity of seizures by sending regular, mild pulses of electrical energy to the brain via the vagus nerve.
