Epilepsy, depression, and stroke are just some of the debilitating medical conditions that individuals around the world struggle with. While there is still much to be understood about these conditions, one method that is showing great promise in treating these conditions is vagus nerve stimulation (VNS). This medical approach involves indirectly stimulating the brain by implanting a pacemaker-like device under the skin in the upper chest, which sends electrical impulses to the vagus nerve. This nerve is one of the twelve cranial nerves that conduct signals between the brain and other body locations, and is responsible for many of the body's functions.
In patients with epilepsy, VNS has been found to disrupt the abnormal brain patterns that cause seizures. This occurs either by spreading electric current into a wide area of the brain to disrupt the overexcitement or by causing the release of neurotransmitters that decrease seizure activity. For individuals with depression, VNS has been found to alter the levels of specific neurotransmitters in the brain that regulate mood. In stroke rehabilitation, VNS has been shown to stimulate the motor cortex area in the brain to improve arm and hand function.
Despite the success of VNS, researchers are still not exactly sure how it works. However, the evidence shows that VNS can play a vital role in managing seizures, depression, and stroke by altering the way brain cells work. The device is adjustable and patients are given a handheld magnet to generate an electric current to stop seizures or reduce their severity.
Vagus nerve stimulation is a promising treatment option for individuals with epilepsy, depression, and stroke who haven't had success with traditional treatments. With its ability to alter the way brain cells work, VNS may be a game-changer for individuals struggling with these debilitating conditions.
